Valve position sensors for monitoring fittings and actuators.
A new concept from Pepperl+Fuchs combines two devices, as a ‘dual sensor’, in one housing to reduce mounting and maintenance costs considerably. Solutions for classic enclosure installation are available as are sensors for direct mount on the actuator. Devices approved for hazardous area operation are also available.
Direct mount sensors
Series F31 and F31K provide a solution for position feedback that enables direct, stable, and durable mounting of the sensor and actuator. F31 and F31K are suitable for direct mounting on drives with no additional mounting fittings required. Users can request the position of all normal drives, irrespective of size and make, with just two actuators. Series F31K offers a terminal compartment with cage clamp technology or screw terminals for system and valve connection.
Versions with one, two, and without valve connections are available. The valve controller can be directly connected via the sensor connection if required to reduce mounting time and wiring costs.
With series F25 sensors, Pepperl+Fuchs also offer an interesting solution for position feedback of manually operated ball and butterfly valves.
Features
* Safe – the dimensions of the sensor as well as the distances between the sensor and actuator are selected such that the system involves no risk of injury during operation (which is TÜV certified).
* Variable – the sensors are suitable for all normal drives irrespective of size and make.
* Fixed – because of the round mounting holes in the sensor enclosure, alignment is retained after a sensor is changed.
* Universal – clockwise and counter clockwise drives can be scanned.
* Unambiguous – the assignment of the actuator to the hole pattern of the drive is clear and the actuator position is plainly visible.
* Diverse – you can choose between cable connection, plug connection (V1, V16, or V18), and terminal compartment connection.
* Transparent – the switching states, supply voltage, and valve controller are clearly indicated via LEDs.
