Digital readouts are specialized displays for position and dimension readings from inspection gages and linear scales, or rotary encoders on machine tools.
Linear variable differential transformer (LVDT) linear position sensors have a series of inductors in a hollow cylindrical shaft and a solid cylindrical core. These devices produce an electrical output proportional to the position of the core
Position probes measure the position of a target surface, usually with a high degree of accuracy. This search form covers many different linear position products.
Pressure transmitters translate the low level output of a sensor or transducer to a higher level signal suitable for transmission to a site where it can be further processed. These devices include pressure sensors, transducers, elements, and instruments.
Resistance temperature detector (RTD) temperature transmitters convert RTD resistance measurements to current signals, eliminating the problems inherent in RTD signal transmission via lead resistance.
Sensor transmitters are measurement or signal conditioning packages that provide a standard, calibrated output from a sensor or transducer in the form of a current loop output (e.g., 4-20 mA).
Signal conditioning products provide amplification, filtering, converting, and other processes required to make sensor output suitable for reading by computer boards.
Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches.
Thermocouple temperature transmitters convert the small millivolt output of a thermocouple to a current signal (typically 4-20 mADC) that is immune to noise and voltage drops over a long distance.
Underwater acoustic transducers contain both transmitters and receivers and use distance and directional data for communication, mapping and navigation.
