4-20mA TRANSMITTERS WITH HART PROTOCOL

The 2-wire position transmitter with HART will generate

a nominal 4-20mA signal proportional to valve position

output for full-range actuation of the valve. The transmitter is capable of

generating signals below 4mA and above 20mA if the position sensor indi-

cates an out-of-range value. With the added HART digital communication

capability, remote calibration and parameter conﬁguration

can be performed via a handheld.

Features:

•

Remote set point calibration using a handheld device

for calibration and monitoring

•

Selectable over and under travel settings

•

4 to 20mA variable reading

•

Monitoring and setting of alarms with advanced diagnostics.

Includes deadband detection, out of range indication and

detection of internal memory errors
