Description
The Loop Powered Universal Indicator is an advanced field and panel instrumentation device designed to measure, display, and transmit industrial process signals without requiring a separate power supply. Powered directly from the 4–20 mA current loop, the instrument simplifies installation, reduces wiring costs, and improves reliability in remote process locations where auxiliary power may not be available. Supporting RTD, thermocouple, resistance, potentiometer, voltage, and millivolt inputs, it provides a versatile solution for monitoring temperature and other process variables across a wide range of industrial applications.
The FLP-TT Loop Powered Universal Indicator accepts 3-wire and 4-wire Pt100 RTD sensors, standard thermocouple types (E, J, K, T, B, R, S, N), resistance inputs, DC voltage, and millivolt signals, making it suitable for diverse instrumentation requirements.
