A new position sensor kit has been released in Australia to fit Norgren’s Buschjost range of angle seat valves.
The position sensor gives positive detection of the valve position (open or closed) to provide feedback to the control system. The sensor kit can be easily retrofitted to existing valves by simply removing the top actuator head plug.
The brass sensor kit is threaded into the head with a magnetic spindle threading into the actuator piston. Disassembly of the valve or actuator head is not required. An innovative feature of the angle seat valve position sensor kit is that standard Norgren M/50 series switches are used.
The M/50 switch fits all other Norgren standard cylinders and rodless cylinders. Using a standard switch enables a range of switch types to be used from standard reed to PNP solid state. The M/50 switches are available in high temperature version with optional cables up to 5 metre length or M8 electrical plug connection.
Water and dust rating for the switches is IP65. The M/50 switch is flush mount meaning no surface other than the cable protrudes beyond the sensor kit. This minimises the risk of damage to the switch. The LED indicator on the switches provides good visual indication of the valve position.
