PX633 Submersible Level Transmitter is designed for dealing with the most demanding level measurement conditions. The sensor adopts advanced microprocessor technology with comprehensive linear and temperature error compensation assuring the high precision measurements.
The probe employs full potting, reference tube condensation countermeasures, a dual seal design, and a rugged stainless steel body to assure long term reliability, performance, and stability. The signal transmitting module has transient voltage protection to assure operation under the harsh surge voltage environments (surge protection is not guaranteed and is not covered by warranty). An inverted cone seal extends working life of cable and transducer in conditions were the sensor may experience severe stress from turbulent process media. PX633 Submersible level transmitter is the optimal choice to satisfy all of high demand level measuring applications.

Questions & Answers

What is the chemical compatibility of the PUR cable for this sensor? Looking at a vinegar application (Acetic acid). Is this cable compatible with a liquid like this?

Asked by: Leon from Michigan

A 20% concentration of Acetic Acid would have a minor to moderate effect on the polyurethane coating on the cable
