The KFS 140 is a capacitive humidity sensor in a TO enclosure with an integrated stainless-steel sintered filter. The mechanical construction is extremely robust thanks to the metal enclosure.

Particularly noteworthy are the wide range of applications, low hysteresis and linear characteristic curve. The high-performance polymer composite is resistant to condensation and many chemical influences and guarantees excellent long-term stability.

The connectors are set in the glass, gas-tight base making the enclosure suitable for use as a pressure-resistant joint between the process chamber and evaluation electronics. A typical application is, for example, measuring the pressure dew point in pneumatic systems. Optimum performance makes the sensor ideal for demanding tasks in industrial measurement technology.
