DUCT HUMIDITY- AND TEMPERATURE SENSORS KFTF-MB
Calibratable duct humidity and temperature sensor KFTF-T3 (± 2.0%) with
Modbus RTU connection, in a resistant IP65 plastic housing with quick-
locking screws and M16 cable gland for cable connection and a plastic
sinter filter (exchangeable). Including mounting flange to detect the
relative humidity (0…100% RH) and the temperature (–35...+80 °C) inside
a tube, including various parameters in the humidity measurement. The
duct sensor is applied in a non-aggressive and dust-free environment and
is suitable for installation in ceilings, ducts and devices.
