Self-Contained, Optical Leak Detector
The HPQ-D leak detection sensor family is the first of its kind to be constructed entirely of sealed, Teflon(r) PFA material and be configured in a self-contained package smaller than a quarter. It does not require a fiberoptic amplifier to be used since there is a useable NPN or PNP transistor output with each sensor. Typically, only 1ml of liquid in contact with the optical focal point will change the sensor’s output. This enables early detection of caustic chemical spills and can be usedto shut down the tool immediately, which minimizes the environmental impact.
A large gain signal difference between no liquid and liquid detection ensures low probability of false detection. The fail safe design provides a normally closed output that turns off when liquid is detected.
Easily viewable green LED signifies normal operation and an orange LED turns on when liquid is detected and output is shut off. The bracket assembly is made of CPVC material and has an over/under patented style that assures solid retention once locked down and the ability to remove the sensor for maintenance or output checking.
The underside of bracket is flat and has perforated mounting holes so you can mount with hardware or adhesive.
