The EPIC noncontact position transmitter represented a significant departure from previous attempts to reliably measure the position of rotary control valves. As opposed to conventional devices, couplers are not utilised. A magnetic proximity module, attached to the actuator output shaft is the only 'moving' part in the transmitter. Sensing is performed totally by noncontacting means, based upon characterisation of flux strength as a function of axial position.
A solid-state sensor is employed, whose output is a function of both flux density and excitation voltage. That property allows the use of an internal bridge circuit for accurate zero adjustment, where one arm of the bridge is comprised of the sensor, and the other comprised of a resistive divider for zero reference.
Transmitter output is 4-20 mA, two-wire, with compliance voltage ranging from 14,5 to 35 V. Output updating takes place 20 times per second, allowing use of the transmitter for applications not possible with transmitters of other types. The inherent reliability of the transmitter permits use of advanced control strategies, where knowledge of valve position can be used in predictive and other algorithms.
