Loop powered devices are modules and computer boards which are powered by the system they serve. They derive their power from the input current loop instead of from an external or additional power source

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

Vibration transmitters provide electrical outputs that are proportional to vibration inputs

Signal isolators must be used when connecting grounded signal sources to grounded signal followers. If the speed control input of an adjustable frequency drive is grounded, any input signal must be ungrounded.

Specialty industrial process controllers are used in unlisted, specialized or proprietary applications.

Humidity controllers monitor and maintain proper humidity levels in environmental test applications, food storage areas, and electronic equipment rooms.

Pressure switches are actuated by a change in the pressure of a liquid or gas.  They activate electromechanical or solid-state switches upon reaching a specific pressure level.

Tachometers are used to measure the velocity of a rotating object. They operate on the principle that a driven motor (i.e., a motor operated as a generator) produces a voltage that is proportional to the angular velocity of the motor shaft.

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

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

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

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

Current loop converters convert an analog or digital signal to a current loop output such as 4-20 mA or 0-20 mA

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

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
