Benefits and Features

  • Ideal applications include motor or generator load conditions, efficiency studies, intermittent fault detection, and rough submetering
  • No direct electrical connection to the electrical system

The "-L" on a product model indicates that the cable length is specified at the time of order.


Detailed Description

The CS15 detects the ac current along an electrical wire using the magnetic field that is generated by that current. It is external to the wire jacket and has no direct electrical connection to the system. This transducer outputs a millivolt signal that our CR200(X)-series dataloggers can directly measure.

The CS15 can be used for motor or generator load condition monitoring, efficiency studies, intermittent fault detection, and rough submetering.

Data Logger Considerations

The CS15 was designed specifically for the CR200(X)-series dataloggers. It is measured with the VoltSE instruction. The measurement is generally taken repeatedly inside a measurement loop, then the RMS (root-mean-square) value is determined.

Frequently Asked Questions

Number of FAQs related to CS15-L: 2

  1. Yes, by connecting the red wire to ground rather than its normal location.
  2. Not directly. If the CS15-L is connected to a CR200(X) datalogger, the data logger can take the ac measurement and control a solid-state relay based on some threshold within the data logger program. The solid-state relay can then control other relays, solenoids, or motor starters. (Use of a solid-state relay is preferred because the data logger can trigger it with a small 5 Vdc mA signal.) For more information, see the “Measurement and Control Peripherals” section of the operator’s manual.
