Capacitive Air Gap Sensor
Brand: IRIS PowerCapacitive Air Gap Sensors measure the distance between the rotor and stator in hydroelectric generators to avoid reduced efficiency or damage caused by off-center or out-of-round conditions.
Features- Capacitive Sensor Technology
- Output directly proportional to the air gap distance (pole profile)
- Easy to install and no special calibration needed
- Low Profile (3 types)
- High Temperature Stability
- Immune to magnetic fields, dust, oil, EMI, RFI
- The air gap sensor comes in a kit with a signal conditioner, junction box and mounting epoxy
