|The HPF-D040 fiberoptic leak detector is inherently safe in that there is no circuitry at the sensing point, only light from the associated amplifier. The amplifier would be mounted out of the immediate sensing area. The small and narrow sensing head and bracket are composed of chemically resistant Teflon(r) PFA material.
A detachable mounting bracket block with an integral 316SS mounting grommet insures adequate retention while offering easy maintenance capability. The 5 meters of cable length has a 60 micron covering of PFA material that provides chemical protection along with field cut-to-desired-length ability.
Quick detection of spills is adjustable via the amplifier used. 1ml of liquid typically is required to change the amplifier’s state. The fail safe design is achieved by conducting light back to the amplifier when liquid is not present. Liquid presence or a cable break will stop the light from being returned. Unlike the self-contained version and competitive offerings, the customer’s pan is used to stabilize and adjust the light return when setting the amplifier. If the sensor becomes unattached and no longer sees the pan reflection, the output will turn off. We call this “floating head detection” capability.
