Operating Manual |
1.PRODUCT DESCRIPTION
The HMW60 transmitters are wall mounted truly two-wire transmitters for the measurement of humidity (HMW60U) and for the measurement of humidity and temperature (HMW60Y).
The HMW60U/Y transmitters can be mounted directly on the wall. Thye are easy to install and maintain. One point calibration is easily performed with the HMI41 indicator and the calibration cable 19116ZZ.
Both transmitter types incorporate the HUMICAP® 180 humidity sensor which uses an operating principle based on changes in the capacitance of a thin polymer film as it absorbs water molecules. The HMW60Y transmitters mesure temperature with the reliable Pt 1000 sensor.
