Load Cell TransmitterThe Load Cell Transmitter have been specially designed for use in harsh industrial environments with their lP65 (plastic) or lP67 (cast aluminum) enclosures. This model can power a single 120-350 ohm load cell with 1W bridge excitation voltage. The model accepts 1 b 3 mVN input spinal and generates a standard 4h.20 m three-wire output signal that can be safely sent over long stances to remote indicators, data loggers, or controllers. Zero and Span adjustments, can be performed using built-in potentiometers. The Transmitters are low-priced and can withstand considerable electromagnetic disturbances. They can be a preferable low- cost solution for general-purpose process weighting as well as tension measurement applications. TRW-OL Series Input Type: Single Load Cell Input Signal:
- OL1- 1mV/V
- OL2- 2mV/V
