MICRO-SET MSD2 prover sphere detector
The MICRO-SET MSD2 prover sphere detector is a mechanically activated position sensor for signalling the passage of a meter prover sphere. The unit is bolted to the prover loop pipe by means of a mounting boss, this allows the MICRO-SET MSD2 plunger to protrude through the pipe wall and the prover sphere depresses the plunger as it passes. The plunger is fitted with magnets which actuate a fully encapsulated SPST reed assembly and accurately signals the sphere position within the prover.
The MICRO-SET MSD2 ball prover detector switch features a single mechanical moving part: a pressure balanced plunger/piston with no dynamic seals. The plunger is 100% bi-directional and fully nickel PTFE coated to prevent wear from abrasive particles and ensure optimum long life.
