Capacitive dew-point transmitter HD/HR - 200

G 1/24-20 mA2-wire

Product
HD/HR - 200: moisture and dewpoint transmitter with capacitive sensing and 4–20 mA (2‑wire) output.

Overview
The HD/HR - 200 measures dewpoint (°C) and relative moisture (% rH) in gases. It supports gas temperatures up to 200 °C, a maximum operating pressure of 10 bar and is powered from a 12–28 V supply. The unit includes a 2-line LCD for TP/T readout and an IP65 enclosure for industrial installations.
