Our OM Series load cell signal conditioners are used when a digital display is not needed, such as applications which the weighing system is controlled or monitored by a computer or PLC. These units supply the needed excitation voltage to power up to four 350 ohm bridge load cells. The wide range of models offered provide a variety of accuracy and frequency response levels, and signal outputs such as 0-10VDC, +/-10VDC, 4-20mA, RS232, RS485, and frequency. DC powered units are also available.
The rugged epoxy encapsulated design allows for use in the harshest of environments.

Below is a reference table to choose the appropriate model for your application, or simply contact us with your application information.
