Digital Epic D410/D420 Position Transmitter
Brand: WestlockPosition Transmitters that provide discrete position control and precision, non-contact position feedback with digital communication via HART protocol for linear or rotary control valves in a simple, integrated package.
Features- Microprocessor based technology allows digital communication via HART protocol
- Model D410 features remote and local partial stroke test (PST) and emergency shut down (ESD) initiated remotely via HART signal or locally at the device for safety system applications
- ‘Non-intrusive’ magnetic calibration input sensors on outside of the D410 enclosure allow calibration without removing the cover, maintaining safety in a potentially explosive environment
- Valve position measurement via a noncontact magnetic sensor eliminates mechanical drive arms or linkages increasing reliability in high cycle applications or where vibration is present
- Highly visible position indicator
- Site glass on Model D410 gives view to the product’s LCD display
- Extra conduit entries and internal terminal points are provided for mounting and backwiring of a solenoid valve
- Low copper content aluminum enclosure with polyurethane enamel coating assures both strength and corrosion resistance
