Burkert introduces enamel layer pH sensors

A Burkert Fluid Control Systems product story
Edited by the Engineeringtalk editorial team Dec 16, 2008

Burkert has developed a new metering principle by replacing the glass membrane on pH sensors with an enamel layer.

Benefits of enamel sensors are that they are unbreakable, so are less susceptible to errors in production; they do not need to be removed for cleaning and recalibration; they are suitable for CIP and SIP; and they can be cleaned with acid as well as basic solvents, in situ, and steam-sterilised.

The new metering principle features an ionic sensitive enamel layer burned onto a stainless steel tube.

The enamel layer provides a smooth surface that stops media from sticking during measurement.

A polished surface for the wetted parts and hygienic installation fittings make the sensor system easy to clean.

During cleaning operations and CIP/SIP purification, the sensor stays in the process and does not require recalibration.

This saves time and costs and ensures sterility of the end product when changing batches.

Because enamel sensors do not have to be removed or recalibrated, processes are not exposed to the risks of germs or contamination.

The enamel pH sensor can be left dry for extended periods without any drying out or loss of performance.
