Electrical Position Indicators can be used to reliably detect the position of a pneumatically operated actuator. The electronic microprocessor provides evaluation of the actuator position facilitating commissioning and support during the operation. The position is displayed via high-visibility LEDs and fed back via electrical signals.
The Combi Switchbox goes a step further by recording the end position of the process valve and transmitting it to the plant control system. The integrated pilot valve also makes it possible to actuate the valve with the Combi Switchbox. In plants with strict safety or quality requirements, the Combi Switchbox allows reliable monitoring of installed valves.
The GEMU Type 1230 electrical position indicator is suitable for linear valves with actuator strokes up to 20 mm (actuating travel). It has a corrosion resistant housing and one or two micro switches. Switching rod and actuating spindle have a positive connection without axial play. The electrical connection is via cable gland.
The GEMU Type 1235 is a microprocessor controlled programmable intelligent position indicator with an integral electronic travel sensor system (stroke). Optical position indication is made by LED and electrical position indication by relay with galvanically separated switch outputs. The housing cover is made of corrosion resistant plastic and the base is PVDF with sealing to IP 67.
The GEMU Type 1236 is a microprocessor controlled programmable intelligent position indicator with an integral electronic travel sensor system (stroke). Optical position indication is made by LED and electrical position indication by relay with galvanically separated switch outputs. The housing cover is made of corrosion resistant plastic and the base is stainless steel with sealing to IP 67.
The GEMU Type 4242 combi switchbox is suitable for mounting to pneumatically operated linear actuators. Secure connection to valve spindle means reliable feedback signal. Integrated pilot valves enable direct activation of the process valve connected to them. Intelligent microprocessor controlled functions make commissioning and support during operation easier. The current position of the valve is displayed via high visibility LEDs and fed back via electrical signals. The GEMU 4242 has been specially designed for valves with a stroke of 2 to 75 mm.
