Polymer housing makes sensor food safe
Endress + Hauser chose Victrex Peek polymer for the housing of the Indumax H CLS54 conductivity sensor to meet the extreme demands of the food industry.
When Endress + Hauser, a global leader in measurement instrumentation, was developing its new Indumax H CLS54 conductivity sensor, it chose Victrex Peek polymer for the housing because of the material's ability to meet the extreme demands of the food industry The sensor is used for inductive conductivity measurement of liquids in the food and beverage industry as well as the chemical industry

Polymer protects cylinder head gasket
When STE developed its new Monomet cylinder head gasket, it used a powder coating compound of Victrex Peek polymer and PTFE.
According to Andrew Ragan, Product Manager, Victrex USA: "The outstanding chemical resistance of Victrex Peek polymer to all common solvents, acids and bases ensures that the sensor can be used in direct contact with aggressive media".
"And, because Victrex Peek polymer conforms with FDA requirements for repeated food contact, it is safe to use in the food and beverage industry".
The sensor's Victrex Peek polymer housing is completely free of all joints and gaps for optimum hygiene.
"Its high surface quality ensures easy cleaning and prevents the deposition of particles, or contamination of liquids", says Ragan.
"Because Victrex Peek polymer has a continuous use temperature of 260C, the sensor can be sterilised for more than 60 minutes at 150C and 5bar without any degradation".
The Indumax H CLS54 sensor operates in continuous use temperatures ranging from -10 to +125C.
"The polymer's excellent mechanical properties and low creep give the sensor a compressive strength of 12bar at both room temperature and temperatures exceeding the given steam pressure", explains Ragan.
The sensor can also be used in vacuum applications.
The ability to injection mould the sensor housing has automated the production process of the Indumax H CLS54.
By encapsulating the sensor in Victrex Peek polymer the need for seals was eliminated.
This significantly extends the service life of the sensor.
