Overview
The ACC-SEN-CSSPLIT monitors AC current in motors, pumps, fans, and other electrical loads, and reports it to a Wildeye datalogger as a 4–20 mA signal. Use it to confirm when equipment is running, log run hours, and spot changes in load that can point to a blockage, worn impeller, or failing motor.
The split-core design clamps around an existing conductor, so you can install it without disconnecting cables or shutting down the equipment. Each sensor comes with a 1 m cable and M12 connector that plugs straight into a Wildeye NACS 4–20 mA input. There’s no wiring to terminate in the field, and no separate power supply. The sensor is loop-powered from the logger input.
The measurement range can be set to 100, 150, or 200 A with a jumper, so one sensor covers a wide range of equipment. Readings appear in mywildeye in real time, and you can set alerts for start, stop, or out-of-range current.
Installation must be carried out by a qualified electrician. Isolate the circuit before fitting the sensor wherever possible.
-
Clamp the sensor around a single conductor only. Clamping around a complete cable (active and neutral together) will give a zero reading.
-
The ACC-SEN-CSSPLIT measures AC current only.
The sensor is calibrated for sinusoidal current. Readings on loads driven by a variable speed drive (VSD) may be less accurate.
