Sensor handles low di-electric materials
Rechner's 26 series capacitive filling level detection sensor can detect low di-electric materials with complete reliability, virtually ignoring any product build up that may occur.
Rechner's 26 series capacitive filling level detection sensor was initially designed for the detection of very adhesive products The nonstick characteristic of the PTFE housing is enhanced with the round tip of the sensor

Level probes avoid common capacitive problems
Rechner level probes are unique in the way that they work and are now available with evaluation units integral in the head of the level probe.
Proximity sensors come with ATEX certification
Rechner's range of capacitive proximity sensors already includes devices certified StEx "for use in explosion danger areas with combustible dust", and these are now available with ATEX certification.
Shortly after the launch the sensor design was enhanced to "high-performance" (HP), now a standard for Rechner Sensors.
HP sensors involve a change in the electronics and modifications to the electrodes, but the result is a significant improvement in performance.
Typically performance improvements include up to three times the normal sensing distance, stability up to 100C and a sensing distance that is medium optimised, meaning that with one adjustment it is possible to detect a large variety of products.
With the 26 series the electrode modification includes the use of a semicircular electrode.
A combination of the optimal electrode form along with the high-performance circuit ensures that this sensor is no common sensor.
The sensor can sense low di-electric materials with complete reliability, virtually ignoring any product build up that may occur.
This makes the sensor the perfect replacement in many cases for tuning forks or other vibrating sensors.
There is no special orientation required.
The sensors within the 26 series are suitable for the level control of most different products.
With a high-grade PTFE housing, they are used in the semiconductor, chemical industry, and food processing and pharmaceutical industries.
Different process fittings are available and there are models for 10 - 35V DC and 20-250V AC/DC.
This range is completed by models with ATEX certificates for use in areas with danger of explosion, dust zone 20 or gas zone 1.
Versions for 100C are capable of CIP up to 121C for the cleaning or sterilisation of the parts that are in contact with the products.
