Key specifications include the type and intended application, as well as any specific sensor function.
Temperature sensor
Temperature sensors/detectors/converters are electronic devices that detect thermal parameters and provide signals to the input of control and display devices. Temperature sensors typically rely on RTDS or thermistors to measure temperature and convert it to output voltage. Key specifications include sensor/detector type, maximum and minimum measurable temperature, and diameter and length dimensions. Temperature sensors are used to measure the thermal properties of gases, liquids and solids in many process industries and are configured for both general and special uses.
Radiation sensor
A radiation sensor/detector is an electronic device that senses the presence of alpha, beta or gamma particles and provides a signal to a counter and display device. Key specifications include sensor type and minimum and maximum detectable energy. Radiation detectors are used for surveys and sample counts.
Proximity sensor
Proximity sensors are electronic devices used to detect the presence of nearby objects in a non-contact manner. Proximity sensors can detect the presence of an object, usually within a few millimeters, and in doing so produce an output signal, usually DC, to the controller. Proximity sensors are used in countless manufacturing operations to detect the presence of parts and machine components. Key specifications include sensor type, maximum sensing distance, minimum and maximum operating temperature, and diameter and length dimensions. Proximity sensors are typically short-range devices, but can also be used in designs that can detect objects several inches away. A common type of proximity sensor is called a capacitive proximity sensor. The device uses changes in capacitance caused by a reduction in the spacing distance between capacitor plates, one of which is connected to the object being observed, as a means of determining the motion and position of the object from the sensor.
Pressure sensor
Pressure sensors/detectors/converters are electromechanical devices that detect forces per unit area in a gas or liquid and provide signals to the input of control and display devices. Pressure sensors/transducers typically use diaphragm and strain gauge Bridges to detect and measure the force applied per unit area.

Photoelectric sensor
Photoelectric sensors are electronic devices that can sense objects passing within their detection range, but they are also capable of detecting color, cleanliness, and position if needed. These sensors rely on using transmitters and receivers to measure changes in the light they emit. They are common in manufacturing and material handling automation for uses such as counting, robotic picking, and automatic doors and sluice gates.
Particle sensor
Particle sensors/detectors are electronic devices used to sense dust and other airborne particles and provide signals to inputs to control or display devices. Particle sensors are common in the monitoring of garbage cans and bag dust collectors. Key specifications include sensor type, minimum detectable particle size, operating temperature range, sample size, and response time. Particle detectors used in nuclear engineering are called radiation detectors (see above).
Motion sensor
Motion sensors/detectors/transducers are electronic devices that can sense the movement or stop of components, persons, etc., and provide signals to the input of control or display devices. A typical application of motion detection is to detect the stall of a conveyor or the sticking of a bearing. Key specifications include intended applications, sensor types, sensor functions, and minimum and maximum speeds.
Metal sensor
A metal detector is an electronic or electromechanical device used to detect the presence of metal in a variety of situations, from packages to people. Metal detectors can be permanent or portable and rely on many popular electromagnetic sensor technologies. Key specifications include intended applications, maximum sensing distance, and certain functional options, such as handheld and stationary systems. Metal detectors can be customized to explicitly detect metals in a specific manufacturing operation, such as a sawmill or injection molding.
Level sensor
A level sensor/detector is an electronic or electromechanical device used to determine the height of a gas, liquid or solid in a tank or tank and to provide a signal to the input of a control or display device. Typical level sensors use ultrasonic, capacitive, vibratory, or mechanical means to determine product height. Key specifications include sensor type, sensor function and maximum sensing distance. Level sensors/detectors can be contact or non-contact.
sensor
Leak sensors/detectors are electronic devices used to identify or monitor harmful emissions of liquids or gases. For example, some leak detectors rely on ultrasonic means to detect air leaks. Other leak detectors rely on simple blowing agents to measure the firmness of pipe joints. Nevertheless, other leak detectors are still used to measure the effectiveness of seals in vacuum packaging.
Humidity sensor
Humidity sensors/detectors/transmitters are electronic devices that measure water content in the air and convert these measurements into signals that can be used as inputs to control or display devices. Key specifications include maximum response times and minimum and maximum operating temperatures.
Gas and chemical sensors
Gas and chemical sensors/detectors are fixed or portable electronic devices used to sense the presence and properties of various gases or chemicals and relay signals to the input of a controller or visual display. Key specifications include the intended application, sensor/detector type, measurement range, and characteristics. Gas and chemical sensors/detection for confined Spaces, monitor inspection, analytical instruments, etc., are designed to have multiple detection and chemical substance capabilities.
Force transducer
Force sensors/sensors are electronic devices that measure various parameters related to force, such as weight, torque, load, etc., and provide signals to the input of a control or display device. Force sensors typically rely on load cells, which are piezoelectric devices whose resistance changes under deforming loads. Other methods for measuring torque and strain exist. Key specifications include sensor function, number of shafts, minimum and maximum load (or torque), minimum and maximum operating temperature, and the dimensions of various sensors. Force sensors are used in load measurement applications ranging from automotive shocks to tension tensioning devices.
Flow sensor
A flow sensor/detector is an electronic or electromechanical device used to sense the movement of a gas, liquid or solid and to provide a signal to the input of a control or display device. The flow sensor can be all-electronic – using ultrasonic detection from outside the pipe, say – or partly mechanical – for example, a paddle wheel that sits directly in the flow itself and spins. Key specifications include sensor/detector type, sensor function, maximum flow rate, maximum operating pressure, and minimum and maximum operating temperature. Flow sensors are widely used in the processing industry. Some panel mount designs allow for rapid indication of flow conditions to the process operator.
Defect sensor
Defect sensors/detectors are electronic devices used in various manufacturing processes to find inconsistencies in surfaces or underlying materials, such as welds. The flaw detector uses ultrasonic, acoustic or other means to identify defects in materials and can be portable or fixed mount. Key specifications include the sensor type, the range of defects or thicknesses that can be detected, and the intended application.
Flame sensor
A flame detector usually relies on ultraviolet or infrared detection of a flame, for example, a flame detector is usually an optoelectronic device used to sense the presence of induction and the input signal for a flame control device. The burner. A key specification is the detector type. Flame engines can also be used in safe environments, such as under cover systems.
Electric sensor
An electrical sensor/detector/transducer is an electronic device that senses current, voltage, etc., and provides a signal to the input of a control device or visual display. Electronic sensors typically rely on Hall effect detection, but other methods are also used. Key specifications include sensor type, sensor function, minimum and maximum measurement range, and operating temperature range. Electronic sensors are used wherever information about the status of electrical systems is needed and are used in everything from rail systems to fan, pump and heater monitoring.
Contact sensor
A contact sensor is any type of sensing device whose function is to detect conditions by relying on physical contact or contact between the sensor and the object being observed or monitored. A simple type of contact sensor is used in the alarm system to monitor doors, Windows and other access points. When the door or window is closed, the magnetic switch provides an indication to the alarm control unit so that it knows the status of that entry point. Similarly, when a door or window is opened, the contact sensor will warn the alarm controller of the status of that access point and may trigger actions such as activating an audible alarm. Contact sensors have many uses, such as temperature monitoring and proximity sensors in robotics applications and automated machinery.
Non-contact sensor
In contrast to contact sensors, non-contact sensors are devices that operate without a physical contact state between the sensor and the monitored object. An example of a sensor is a motion detector used in safety lights. Use non-mechanical. Or detect objects within the range of the motion detector in a non-physical way, such as by detecting passive infrared energy, microwave energy, ultrasonic energy, etc. Law enforcement uses radar guns to monitor the speed of objects in vehicles as another example of a form of non-contact sensor. Other types of devices that fall into the category of non-contact sensors include Hall effect sensors, inductive sensors, LVDT (linear support differential conversion), RVDT (rotary expansion differential conversion), and eddy current sensors.
