The MultiSensor family provides a very low cost solution for the need to monitor, measure, record and alarm, remote parameters. MultiSensors are not designed for high degrees of accuracy, but are intended more as relative indicators of the conditions they monitor. The enclosures are not weather proof; they are intended for indoor use and to protect the electronics from coming in contact with external items that might cause failure or damage. With the exception of
MS-T, all MultiSensor products measure temperature and one additional parameter.
In addition to temperature measurement, the MS-TC will measure AC current in the range of 0 to 20 amps. While not calibrated, empirical data indicates a typical accuracy of ±3% of reading. The response curve, established at 23 degrees C, is linear from 0.2 VDC (1 amp.) to 3.78 VDC (20 amps.). The zero current reading is 0.09 VDC.
When used with a
Link45, the output will be voltage as stated above. When used with a
LinkTH, the output will be a 3 digit reading from 1.00 to 20.0. Regardless of the Link model used, readings below 1 ampere and above 20 amperes are not specified.
The sensing device used is a clamp-on current transformer. Dimensions are: 1.04"H x 1.04"W x 1.58"H. The "window" or aperture is 0.40" in diameter. The box containing the electronics is shipped with 3 feet of 18-gauge wire extending from it. It is up to the user to add or trim wire as desired and to make the final connection to the current transformer.
