HMD60U/Y is a two-wire humidity and temperature transmitter that is duct mounted and can be disconnected without dismantling the installation.
The manual describes how to mount the HMD60U/Y transmitter in a duct using two screws and a drilling template, with an extra hole for on‑site calibration. It also covers grounding of the signal cable, electrical connections via a removable 5‑pole screw connector, and the use of HMI41 or HM70 indicators for testing.
Procedures for removing and reinstalling the sensor head, replacing the Humicap®180 sensor and membrane or sintered filters, and performing one‑point RH calibration are detailed. Technical data such as measurement ranges, supply voltage, output signal, response time and accuracy are listed, along with EMC test standards and warranty information.
| Relative humidity measurement range | 0…100 %RH |
|---|---|
| Supply voltage | 10…35 VDC |
| Temperature sensor accuracy | better than 0.1 °C |
Mount the transmitter with two screws, using the drilling template on the duct surface and drilling the indicated holes, plus an extra hole for calibration.
