Field mounted indicating controllers consist of two major parts which are found in all models. These are the process variable measurement unit and the indicating controller unit. The controllers measure and adjust basic process variables for temperature, pressure, flow rate, liquid level, and can also handle pneumatic pressure signals.
The entire series features superb functional design with consideration for cost and operability. A full lineup of indicating controllers, indicating transmitters, and indicating transmitting controllers is available for implementation of cost-effective instrumentation that meets a diverse range of functional requirements.
High reliability
We designed this series for both easy operation and improved reliability. Pressurized pneumatic piping is replaced by a pneumatic circuit board to ensure functional reliability, a twin bellows is used for long-term stability, and a metal case makes the unit resistant to heat, water, and weather.
Excellent vibration characteristics
All spiral elements are equipped with a balance weight to suppress PV indicator oscillation. The structure also prevents eccentricity in the central shaft by determining the angle of displacement from the element center.
A bellows type pressure-receiving element is employed, and a torque that is large enough to overcome the force of oscillation is obtained to cancel out PV indicator oscillation.
Countermeasures against process pulsation
Spiral elements with a damping feature that makes them resistant to process pulsation are utilized. Since there is no constriction, there is no need to worry about the possibility of clogging.
