Key Points
- Scaled calibration for proof of flow set-point
- Split and solid core models to 150A
- N.O. 30VAC/DC or 120VAC output
- Optional command relay
- UL/ULC, CE listed
- RoHOS compliant
- PATENT PENDING
Applications
- Detecting belt loss, coupling shear, and mechanical failure on fans and pumps
- Monitoring status of industrial processes
- Monitoring status of critical motors
PreSet™ allows for matching sensor set-point to the motor nameplate, eliminating the need to calibrate in energized enclosures and reducing installation time. Sensor will detect motor undercurrent conditions such as belt loss, coupling shear, and mechanical failure on fans and pumps. PATENT PENDING
Save time and money while eliminating calibration inside energized enclosures
- Preset™ scaled calibration enables set-point adjustment for proof of flow by simply matching dial to motor full load amps (FLA) nameplate
- Safer: Eliminates calibration in energized enclosures, reduces arc flash hazard
- No need to return to calibrate—saves time and money
- Super low turn-on
Maintenance-free—no call backs
- Superior to differential pressure sensors
- Industry leading 7 year warranty
Set-point operation
- Detects Belt Loss/Coupling Shear!
- Now you can easily detect when drive belts slip, break, or pump coupling shear. In fact, a typical HVAC motor that loses its load has a reduction of current draw of up to 50%. That’s why our sensors are the industry standard for status.
