For extreme ambient or product-temperature conditions, the Rechner series 250 or "KXS-Extreme" are available with high temperature sensors up to +250 °C and remote electronics.
The sensors in the series 250 are integrated in PTFE or PTFE / VA housings. The FEP-coated sensor cable, in the lengths 2m and 5m, is the connection to the evaluation unit and may also be used under high-temperature conditions.
The evaluation unit is connected to the sensor by means of a plug-in connector. On the sensor side, the cable is permanently cast in or equipped with a temperature-resistant plug-in-connector (…Y-version).
The sensing distance for high temperature sensors can be adjusted on the evaluation unit and the switching state is displayed by a LED. The sensing distance adjustment should be made at operating temperature.
