AMA RM-044 Signal Conditioning Unit

AMA RM-044 Signal Conditioning Unit

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. It can also be factory configured for ½ Bridge and ¼ bridge 120 ohm and 350 ohm strain gauges. Gain selection and gross offset correction and all internally link selectable. The electronics is housed in a 100x115x20mm 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.
