Sensors

The sensors are 100 kOhm NTC's. These sensors are available in several shapes:

- bare sensor, for integration in equipment or for special tests
The sensors have a diameter of approximately 2mm. A bare sensor has a very small heat capacity and will hardly influence the measuring set-up. A bare sensor has the fastest response time.

- in a stainless steel tube
The sensors can be delivered in a stainless steel tube with a diameter of 3 or 6 mm. The maximum length is 100 mm. This sensor is watertight. The cable length can be specified with the order. There are special reducers that can be used to mount the sensors in 12 mm conduit pipes.
