1. PRODUCT DESCRIPTION

The HMD60 transmitters are duct mounted two-wire transmitters for the

measurement of humidity (HMD60U) and for the measurement of humidity

and temperature (HMD60Y).

The HMD60U/Y transmitters are easy to install and maintain: the electronics

can be disconnected without dismantling the installation. 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 HMD60Y transmitters

measure temperature with the reliable Pt 1000 sensor.
