Strain Gauge Transmitter BWT227

The BWT227 is primarily designed for use with strain-gauge type pressure transducers.

Description

The BWT227 is primarily designed for use with strain-gauge type pressure transducers. Any other strain gauge devices can be accommodated as long as the bridge resistance is not below 5kΩ for 2-wire output or 350Ω for 3-wire output. Typical applications for separation of transducer and transmitter would be where the transducer is submersed or otherwise inaccessible. Final calibration is trimmed using the front accessible zero and span 15-turn trim adjustments. A front mounted L.E.D. and a test socket verify module function and assist in calibration checks without disconnection of output wires. Standard output is 4-20mA with a minimum supply voltage off 6.3V. This enables the BWT227 to be used in 12V battery supply systems or in automotive applications. Other factory set output configurations are 10 – 50mA loop powered and 0 – 10mA, 0 – 20mA or voltage output in 3-wire connection. Double surge protection is standard with all Series 200 loop powered transmitters to prevent failure due to spikes induced by DC switched inductive loads.
