EDITOR ’ S CHOICE THE NEW MVQ201 VALVE SENSOR
IFM ifm provides all-in-one control and monitoring for quarter-turn valves
Featuring compact construction and easy mounting , the new MVQ201 valve sensor from ifm electronic not only monitors and reports valve position to the nearest degree , but also has an integral M12 connector that can be used for connecting the valve . With this option , the valve is controlled via the same IO-Link connection used to monitor the sensor , which eliminates the need for separate valve wiring , thereby reducing both installation complexity and cost .
In use , the MVQ201 sensor continually monitors the valve position and makes the position data available to the control system via an IO-Link interface . The sensor can also be programmed to detect changes , such as increased opening and closing times , which might indicate valve faults or blockages , and to report these changes via IO-Link . This makes it an ideal choice for use in condition-based maintenance applications .
A range of accessory mounting adaptors is available to further simplify installation .
Conventional valve-open and valve-closed switching outputs are provided and can be set for normally open or normally closed operation . The valve positions corresponding to the open and closed states can be readily programmed with a convenient one-click auto-teach function . MVQ201 sensors also incorporate a clearly visible status LED that shows the valve position at a glance .
Suitable for use with valves having shafts up to 38 mm in diameter , MVQ201 valve position sensors have an IP65 / IP67 protection rating and an operating temperature range of -25 to + 70 º C . A range of accessory mounting adaptors is available to further simplify installation .
