Detects leaks in and around secondary containment areas.

• Choose between polypropylene (PP) or PFA construction

The optic switch is an excellent choice for leak detection applications in and around the secondary containment vessel of sumps, tanks and pipes. The sensor can be applied in a broad range of liquids including sulfuric acid, jet fuel and de-ionized water. The relay output provides a reliable switch interface with remote devices such as a PLC, SCADA or alarm. For maximum flexibility, the sensor is offered in general purpose and intrinsically safe versions with two probe lengths and PP or PFA PTFE materials.
