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.
International SI units (default) can be switched to Imperial (via
Modbus).
Measuring range: 0...100 % RH (humidity) / – 35...+80 °C (temperature)
Medium: clean air and non-aggressive, non-combustible gases
Deviation, humidity: typical ± 2.0 % (20...80 % RH) at +25 °C, otherwise
± 3.0 %
Deviation, temperature: typical ± 0.2 K at +25 °C
Zero point offset: ± 10 % RH (humidity) / ± 5 °C (temperature)
Power: 24VAC (± 20%) / 15…36VDC - 24DC <1,2W
Operation temperature: –30...+70 °C / –22...+158 °F
T3-IP65 plastic housing with two M20 cable glands
Housing dimensions: 108 x 78.5 x 43.3 mm / 4.25 x 3.1 x 1.7 in
