WITH MAGNETIC SHUT-OFF (MSO)
APPLICATIONS
Well suited for plunger arrival sensing on most wells
FEATURES AND BENEFITS
- Quick and easy installation with firm mounting, reducing vibration that can cause false triggering
- Built-in mounting, therefore no tape, ties or extra clamps are needed for a secure mount
- Extremely low power consumption that does not require power from a third wire, thereby reducing system battery load
- Does not use internal batteries
- Reverse polarity protected, making the installation more foolproof
