A temperature sensor typically relies on an RTD or thermistor to measure temperature and convert it to an output voltage. Temperature sensors are used to measure the thermal characteristics of gases, liquids, and solids in many process industries and are configured for both general- and special-purpose uses.
More information about temperature sensors may be found in our related guide All About Temperature Sensors. Key specifications include sensor type and minimum and maximum detectable energies. Radiation detectors are used for surveys and sample counting. More information about radiation sensors may be found in our related guide All About Radiation Detectors. Proximity Sensors are electronic devices used to detect the presence of nearby objects through non-contacting means. A proximity sensor can detect the presence of objects usually within a range of up to several millimeters, and, doing so, produce a usually dc output signal to a controller.
Proximity sensors are used in countless manufacturing operations to detect the presence of parts and machine components. Proximity sensors are generally short-range devices but are available too in designs that can detect objects up to several inches away. One commonly used type of proximity sensor is known as a capacitive proximity sensor.
This device uses the change in capacitance resulting from a reduction in the separation distance between the plates of a capacitor, one plate of which is attached to the object being observed, as a means of determining motion and position of the object from the sensor. Key specifications include sensor function, minimum and maximum working pressures, full-scale accuracy, along with any features particular to the device.
Pressure sensors are used wherever information about the pressure of a gas or liquid is needed for control or measurement. More information on pressure sensors may be found in our related guide Common Types of Pressure Sensors.
Key specifications include sensor type, sensor function, measurement range, and features that are specific to the sensor type. Position sensors are used wherever positional information is needed in a myriad of control applications. A common position transducer is a so-called string-pot, or string potentiometer. More information about position sensors may be found in our related guide All About Position Sensors. See also proximity sensors. Photoelectric sensors are electrical devices that sense objects passing within their field of detection, although they are also capable of detecting color, cleanliness, and location if needed.
These sensors rely on measuring changes in the light they emit using an emitter and a receiver. They are common in manufacturing and material handling automation for purposes such as counting, robotic picking, and automatic doors and gates. Learn more in our related article on Photoelectric Sensors.
Particle sensors are common in bin and baghouse monitoring. Key specifications include transducer type, minimum detectable particle size, operating temperature range, sample volume, and response time. Particle detectors used in nuclear engineering are referred to as radiation detectors see above. More information about particle sensors may be found in our related guide All About Particle Sensors.
Typical applications of motion detection are detecting the stalling of conveyors or the seizing of bearings.
Key specifications include the intended application, sensor type, sensor function, and minimum and maximum speeds. More information about motion sensors may be found in our related guide All About Motion Sensors. Metal Detectors are electronic or electro-mechanical devices used to sense the presence of metal in a variety of situations ranging from packages to people.
Metal detectors can be permanent or portable and rely on a number of sensor technologies with electromagnetics being popular. Key specifications include the intended application, maximum sensing distance, and certain feature choices like handheld and fixed systems. Metal detectors can be tailored to explicitly detect metal in specific manufacturing operations such as sawmilling or injection molding. Typical level sensors use ultrasonic, capacitance, vibratory, or mechanical means to determine product height.
Key specifications include sensor type, sensor function, and maximum sensing distance. More information about level sensors may be found in our related guide All About Level Sensors. Some leak detectors rely on ultrasonic means to detect air leaks, for example. Other leak detectors rely on simple foaming agents to measure the soundness of pipe joints.
Still, other leak detectors are used to measure the effectiveness of the seals in vacuum packages. More information about leak sensors may be found in our related guide All About Leak Sensors. Key specifications include maximum response time and minimum and maximum operating temperatures.
More information about humidity sensors may be found in our related guide All About Humidity Sensors. More information about gas and chemical sensors may be found in our related guide All About Gas and Chemical Sensors. A force sensor typically relies on a load cell, a piezoelectric device whose resistance changes under deforming loads. Other methods exist for measuring torque and strain. Key specifications include sensor function, number of axes, minimum and maximum loads or torques , minimum and maximum operating temperature, as well as the dimensions of the sensor itself.
Force sensors are used in load measuring applications of all kinds, from truck scales to bolt tensioning devices. More information about force sensors may be found in our related guide All About Force Sensors.
A flow sensor can be all electronic—using ultrasonic detection from outside a pipeline, say—or partially mechanical—a paddlewheel, for instance, that sits and spins directly in the flow stream itself.
Flow sensors are used extensively in the processing industries. Some designs for panel mounting allow quick indication of flow conditions to process operators. More information about flow sensors may be found in our related guide All About Flow Sensors.
Flaw detectors use ultrasonic, acoustic, or other means to identify defects in materials and can be portable or fixed installations. Key specifications include sensor type, detectable defect or thickness range, and intended application.
More information about flaw sensors may be found in our related guide All About Flaw Sensors. Flame Detectors are optoelectronic devices used to sense the presence and quality of fire and provide signals to the inputs of control devices. A flame detector typically relies on ultraviolet or infrared detection of the presence of flame and finds use in many combustion control applications such as burners. A key specification is detector type.
Flame detectors find applications in safety settings too, such as in under-the-hood fire suppression systems. More information about flame sensors may be found in our related guide All About Flame Sensors. Electrical sensors often rely on hall effect detection but other methods are used as well.
Key specifications include sensor type, sensor function, minimum and maximum measurement ranges, and operating temperature range. Electrical sensors are used wherever information on the state of an electrical system is needed and are employed in everything from railway systems to fan, pump, and heater monitoring.
More information about electrical sensors may be found in our related guide All About Electrical Sensors. Contact sensors refer to any type of sensing device that functions to detect a condition by relying on physical touch or contact between the sensor and the object being observed or monitored.
A simple type of contact sensor is used in alarm systems to monitor doors, windows, and other access points. When the door or window is closed, a magnetic switch provides an indication to the alarm control unit so that the status of that entry point is known. Similarly, when a door or window is opened, the contact sensor alerts the alarm controller of the state of that access point and may trigger an action such as engaging an audible siren.
There are many uses of contact sensors such as temperature monitoring and as proximity sensors in robotics applications and automated machinery. More information on contact sensors is available in our related guide Types of Contact Sensors. In contrast to contact sensors, non-contact sensors are devices that do not require a physical touch between the sensor and the object being monitored in order to function. A familiar example of this type of sensor is the motion detector used in security lights.
Detection of objects within the range of a motion detector is accomplished using non-mechanical or non-physical means, such as via detection of passive infrared energy, microwave energy, ultrasonic waves, etc.
Radar guns used by law enforcement to monitor the speed of vehicles is another example of a form of non-contact sensor. Other types of devices that fall under the category of non-contact sensors include Hall-effect sensors, inductive sensors, LVDTs linear variable differential transformers , RVDTs rotary variable differential transformers , and Eddy current sensors, to name a few. More information on non-contact sensors is available in our related guide Types of Noncontact Sensors.
A sensor is generally intended to produce a variable signal over some measurement range as opposed to a switch which generally acts in a binary fashion, as in on or off. While this is not always true it helps when it comes to deciding between sensors or switches.
For example, a level switch can detect when a certain specified level in a tank has been reached and signal a pump to stop running.

Но. Увы, она уже знала ответ. Так вот какова месть Танкадо.
Он еще раз сжал его руку, но тут наконец подбежала медсестра. Она вцепилась Беккеру в плечо, заставив его подняться - как раз в тот момент, когда губы старика шевельнулись. Единственное сорвавшееся с них слово фактически не было произнесено. Оно напоминало беззвучный выдох-далекое чувственное воспоминание. - Капля Росы… Крик медсестры гнал его прочь.
