For these sensors it is the dielectric constant of the product that is our focus of attention. For this reason it is important for the measurement that the active surface of the sensor (PEEK tip) is in direct contact with the product that should be detected. The sensor tip must be totally immersed into the product.

The sensors are equipped with Rechner's well-tried EasyTeach function. Both variants are available:
ET = EasyTeach by button
ETW = EasyTeach by wire
With EasyTeach the sensitivity adjustment for the product to be detected is very easy and user-friendly.
It could not be easier. The user mounts the sensor, makes the electrical connection and the adjustment by means of the teach wire and the sensor is ready for use. No additional teach equipment necessary.
Optical guidance during the teach process with the aid of a 2-colour LED: • standby • teach process • switching state.

The modern micro controller controlled temperature compensation provides for reliable level control with applications where there are variations in the ambient temperatures. The sensor body is made of stainless steel Material Nr. 1.4305 (AISI 303).
When the sensor is mounted with our adapters: welding socket or the process adapter Varivent N DN50 a hygienic, EHEDG conforming process connection will be achieved.

Directive (EC) 1935/2004
The traceability of the used plastic material PEEK according to the directive (EC) 1935/2004 is confirmed by RECHNER with a conformity declaration, that is provided on their website as a download document under certificates.
