Conductive level sensor
- Type NKS 11 -
DESCRIPTION
The conductive level sensors are mainly used to detect conductive threshold levels in liquids such as fruit juices, beer,
milk, etc. with a minimum conductivity of 5 µS.
The favourable design, with its sealing cone and the corresponding welding sockets, means that there are no places in
which residues can collect. The sensor is therefore easy to clean and suitable for use in the food and pharmaceutical
industry, etc. CIP- and SIP-suitability are guaranteed.
The non-corrosive materials used for the rod and insulation mean that the sensor is also suitable for corrosive media.
Various process connection forms render optimal adaptation to the application possible. The sensor can be shortened,
which has a positive and practical effect on storage. The electrode is coated with HALAR, which means that the
threshold level detection is also suitable for foaming media.

request
- the maximum permissible torque (15 Nm) must be
taken into account when fitting the sensor
Operating temperature max. 140 ºC - the tank or pipe wall must be made of metal
Environmental
temperature -10...+60 ºC - when installing the sensor, only use the key surface, not the connection head
Operating pressure Pmax = 6 bar - the process connection thread of the sensor must
have free electrical contact to the wall of the pipe/tank
(do not use any insulating sealing materials !)
