3730-1 - ELECTRO-PNEUMATIC POSITIONER

توضیحات

The Type 3730-1 is an entry level electro-pneumatic positioner designed to work in general industrial applications. This positioner can work inherently with single-acting linear and rotary control valves as well as double-acting linear and rotary control valves with the addition of a reversing amplifier.  The digital benefits of the Type 3730-1 provide self-calibration and automatic adaptions to the valve and actuator being controlled.  This entry level digital positioner has preset parameters such that only values deviating from the standard need to be adjusted. With 21 parameters and 15 error codes, most critical settings and information can be communicated.  The HMI (human machine interface) of the single multi-turn push button and LC-display allow this communication of information to occur right at the unit.   The digital positioner is protected against power failure damage to parameters thanks to EEPROM memory storage. The potentiometer-based travel sensor of the Type 3730-1 is not susceptible to wear often found in gear-based travel sensors.  The travel range of the Type 3730-1 can be restricted up to 1/5 maximum stroke as well as operated in split range.
