3730-2 - ELECTRO-PNEUMATIC POSITIONER

توضیحات

The Type 3730-2 is a full feature 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 Type 3730-2 provides self-calibration and automatic adaptions to the valve and actuator being controlled via 4 initialization methods.  This digital positioner has preset parameters such that only values deviating from the standard need to be adjusted. With 50+ parameters and 30+ error codes, the majority of 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 3730-2 is not susceptible to wear often found in gear-based travel sensors.  The travel range of the Type 3730-2 can be restricted up to 1/5 maximum stroke as well as operated in split range.
