JP-450: A magnetically actuated, no-bleed pneumatic point level switch for magnetic level indicators. Magnetic coupling through the chamber wall isolates the switch from process fluid and pressure and allows on-the-fly setpoint adjustment. Two JP-450s paired with a JPLR latching relay provide simple dump/fill valve control.
 

JS-10 / JS-30: Magnetically actuated point level switches (1 amp and 3 amp) for magnetic level indicators. Non-intrusive magnetic coupling isolates the switch from the process and allows easy, on-the-fly setpoint adjustment.
