The CVS 3400 is a CSA approved and Explosion Proof Rated EX d IIC T6/T5, Class 1, Zone 1, Group A. Additional certifications include ATEX and IECEx. The CVS 3400 Smart Positioner accurately controls valve stroke using an input signal of 4 – 20 mA from the controller. The smart positioner uses torque motor control for better resistance to moisture dust and vibration. On board micro processing optimizes the positioner performance and allows for auto calibration, PID control, alarm and *HART protocol. Output characteristics are linear, equal percent, quick open and user specified. The LCD display enables easy monitoring of the position. PID parameters can be easily adjusted in the field by push button, information is transferred with a HART communicator.
