Ideal for critical control loops in refining, chemicals, LNG, power plants and any process where valve performance and predictive diagnostics directly impact product quality and uptime.
Q: How do I upgrade from HART to fieldbus?
A: Simply replace the communication board; the rest of the device remains the same.
Q: What is Online Valve Signature?
A: A unique diagnostic that detects valve friction more accurately during normal operation.
Q: Is the device suitable for single- and double-acting actuators?
A: Yes, the same unit covers both, plus rotary and linear valves.
