Duct Temperature & Humidity Transmitter(RHTX)
The temperature/humidity transmitter serie PTH measures the duct temperature and humidity by a capacitive humidity sensor and
converts the value into a linear output signal 0-10 V DC or 4-20 mA. The humidity and temperature sensor is protected against con-
tamination by a screw sinter filter.
· Humidity measurement for air ducts
· Simple and secure installation
· 0-10V or 4-20mA measuring signals
· Compact size and modern design.
