Designed for panel-mounted measurement, this 1/8 DIN strain gauge panel meter reads strain-gauge and load-cell bridge signals. It shows values on a 4-digit, 9-segment selectable-color LED display, runs on an AC supply, and provides an analog output. Great for load, force, and weight readout.

The OMEGA DP25B Series features the biggest, brightest display of any 1/8 DIN panel meter. The user can select the display color: RED, AMBER, or GREEN.
Unparalleled accuracy in signal conditioning is available in this economical series of panel meters/controllers. The series has a 4-digit, 9-segment display plus optional dual 5 A, SPDT relays (Form "C") and a choice of isolated or non-isolated analog output.
The scalable 0 to 10 Vdc, 0 to 20 mA, or 4 to 20 mA analog output can be used for retransmission of the display value or as a proportional control output, as required. The microprocessor-based DP25B series includes instruments for process (DC voltage and current) strain gage, thermocouple, and RTD.
The DP25B-E process and strain meters accept a wide range of DC voltage and current inputs to cover any typical process application. They feature easy, front-panel scaling to virtually any engineering units, selectable excitation of 4 voltages to work with most transducers and transmitters, front panel and remote tare function for weighing applications, and a hardware lockout to prevent unauthorized changes in set-up.
