Unbranded Yellow Plastic Flow Transmitter PO and R Adjustment Industrial Sensor

Unbranded Yellow Plastic Flow Transmitter PO and R Adjustment Industrial Sensor

This is an unbranded compact yellow plastic Flow Transmitter designed for industrial process flow measurement and control. The front face features a rectangular indicator/display window, an INPUT label, and clearly marked PO and R adjustment terminals (each with + and − positions), used to calibrate or trim the transmitter's offset and range output. A multi-pin connector block is mounted on the rear for signal and power wiring.

Applications

Flow transmitters of this type are used in industrial process control systems to convert a raw flow sensor signal into a standardized output signal suitable for a PLC, controller, or data acquisition system. The PO (offset) and R (range/span) adjustments allow field calibration so the transmitter output accurately represents the measured flow range. Devices like this are common in water treatment, HVAC, chemical processing, and general manufacturing environments where flow monitoring and feedback are part of a closed-loop control system. The compact plastic housing is typical of transmitters designed for panel mounting or inline installation in light-duty industrial or instrumentation applications.
