Proximity Cycle Switches

The Proximity Cycle Switches are magnetically operated single throw switches that sense the movement of the divider valve piston when it is cycling. Each proximity cycle switch provides a signal that is used to monitor the sys- tem. There are 3 different types of switches available.

Reed Type Proximity Switch: Can be used with oil applications only for MS, MH and MGO divider valves at pres- sures up to 518 bar (7500 psi, 52 MPa) at cycle rates under 60 cycles per minute.

Field Sensitive Magnetic Proximity Switch: Dry contact, ceramic magnet operated switch. Used at pressures that do not exceed 242 bar (3500 psi, 24 MPa) at cycle rates up to 200 cycles per minute. Used in MS/MH, MX/MXP and MGO divider valves. An explosion proof version for MS/MH divider valves is available.

Magnetic Operated Proximity Switch: Not limited to valve size. Miniature snap-action switch is tripped by attraction of internal magnet to the moving divider piston. Can be used at pressures up to 518 bar (7500 psi) at cycle rates that do not exceed 150 cycles per minute.
