Built 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 a 10 to 32 V DC supply, and provides an isolated analog output and dual 5 A relays. Best for strain-gauge and load-cell monitoring.

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.
