Humidity Sensors FK120J (capacitive) Humidity-Temperature Sensors / TFK120J (capacitive)
- for semi-industrial and industrial applications
- operating temperature up to +60 °C
- humidity measuring range 0...100% r.F.
- with voltage or current outputsignal:
0...1 V, 0...10V, 4..20 mA - room-version
General information
Accuracy
- Humidity ± 2 %rh 40...60 %rh (otherwise 2,5 %rh)
- Temperature ± 0,2 K with voltage
± 0,3 K with current
The sensors of the FK Series are very robust humidity and temperature sensors, providing highly accurate measurements across the entire measuring range. They are available in duct mount and indoor versions, and their excellent measuring characteristics have made them some of the best-selling items for semi-industrial and industrial applications.
