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

pH transmitters provide electrical outputs that are proportional to potential of hydrogen (pH) inputs

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

Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point

Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. For each measurement, they provide an electrical output that is proportional to the input level

Resistance temperature detector (RTD) temperature transmitters convert RTD resistance measurements to current signals, eliminating the problems inherent in RTD signal transmission via lead resistance

Telemetry receivers and telemetry transmitters are data acquisition components used to gather information from remote locations via wireless communication

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. 

Flow transmitters provide electrical outputs that are proportional to flow inputs. They use flow meters to measure the flow of liquids and gases

Humidity transmitters provide electrical outputs that are proportional to humidity inputs. They measure variables such as relative humidity, absolute humidity, specific humidity, moisture content, dew point, temperature, and pressure

RF transmitters are electronic devices consisting of an oscillator, modulator, and other circuits that produce an RF signal

Vibration transmitters provide electrical outputs that are proportional to vibration inputs

Pressure sensors include all sensors, transducers and elements that produce an electrical signal proportional to pressure or changes in pressure

Vibration sensors cover sensors and other instruments used for measuring vibration and acceleration

Ultrasonic proximity sensors use reflected or transmitted ultrasonic waves to detect the presence or absence of a target component
