Walchem’s LPR corrosion sensors, in combination with the WCT900 Series controllers, offer a cost effective and reliable solution to your corrosion monitoring and controlling needs. Each card provides two Linear Polarization Resistance (LPR) sensor inputs to measure or control the corrosion rate and corrosion imbalance (pitting) of two different alloys in the cooling tower.
The sensor uses standard 5 cm² surface area electrodes.
Where other corrosion sensors are extremely expensive or require the installation of a calibration tip to test for functionality, the Walchem corrosion sensor is very economical and does a diagnostic check before every measurement, without tip replacement.
The need to calibrate with a “tip” is replaced by our innovative electronic design, and the W900 controller can notify you immediately if there is a problem. Two corrosion sensors can be installed monitoring multiple cooling tower materials.
Walchem LPR Corrosion Sensor Benefits:
- Reliable 4-wire design
