The Type 3731–3 Positioner with Hart communication from Samson has the same features as its small brother 3730–3: low power consumption and convenient configuration. Only one rotar pushbutton is needed for start-up: turn to select parameters and push to activate them.
This convenient method of operation is still possible in hazardous areas. The shaft design of the rotary pushbutton through the housing is flameproof. The explosion-proof enclosure with separate terminal compartment allows direct cable entry or connection without spark barriers for cable conduit systems. Thanks to its high-performance microprocessor, the positioner is easy to operate and versatile in function. The analog control helps the positioner achieve an unsurpassed positioning performance, allowing the microprocessor to concentrate on other tasks. This is why the Expert valve diagnostics are fully integrated into the positioners, supplying the required information for predictive maintenance.
