RM-044 Signal Conditioning Unit
Description:
- The RM-044 is a low-cost, stand-alone instrument designed to offer signal conditioning for strain gauge type transducers such as pressure transducers and load cell.
- Supports Stain Gauge Work: ½ Bridge and ¼ Bridge 120- and 350-Ohm Strain Gauges. Internal Bridge completion provided.
- Gain and gross offset correction are both adjustable, as are all internal links.
- The electronics are enclosed in a 100 x 115 x 20 mm polycarbonate enclosure.
- Four 3-pin connectors are supplied for signal, transducer, and power connections.
- The RM-044 typically outputs +10 volts across the transducer's whole range, but it can also drive over a ±10-volt range.
- If necessary, the output can generate signals ranging from 4 to 20 mA.
