The RM-044 has been designed as a low cost, stand-alone unit to provide signal conditioning for strain gauge type transducers such as Pressure Transducers and Load Cells.
Supports Stain Gauge work

½ Bridge and ¼ bridge 120 ohm and 350 ohm strain gauges. Internal Bridge completion supplied. Gain selection and gross offset correction and all internally link selectable.

The electronics is housed in a 100 x 115 x 20 mm-plastic housing.

Four, three 3-pin connectors are provided for signal, transducer and power connections. The RM-044 is normally supplied to provide + 10 volts output for the full range of the transducer but the output will drive over the full range of ± 10 volts. The output is also configured to provide 4 to 20mA signals if required.
