PROTECTION SENSOR AGAINST DRY RUNNING
Sensor for detecting the presence of water based on the optoelectronic principle, therefore non invasive and with no
moving parts. The sensor provides an electronic contact to be used to stop the pump in the event of a lack of water in
the seal area. The sensor opens the electronic contact after a factory-set delay (10 secs).
The sensor is supplied in a kit complete with 2m of cable, a gasket O-ring EPDM, and a stainless steel adapter.
The sensor can also be used in the following applications:The sensor can also be used in the following applications:

The sensor can also be used in the following applications:
Checking the level in water buffer tanks.
Checking the level in pressure tanks.
Checking leaks.

The sensor is suitable for being connected directly on the
filing cap of pumps in the e-SV
TM
series.
An adapter cap is supplied for the 33..125SV series.
Operation is independent of the hardness and conductivity of
the water. The sensor is not suitable for detecting frozen liquids.

Operating principleOperating principle
Operating principleOperating principle
Operating principle
Operation is based on the variation of the refractive index on the surfaces.
The optic sensor comprises a glass cap with inserted a transmitter and an
infrared receiver.
Mirror effect. In the absence of fluid, all the infrared light emitted is internally
reflected by the surface of the glass cap of the receiver.
In the presence of fluid, the refractive index of the surface changes. Most of
the emitted infrared light is dispersed in the fluid. The receiver receives less
light, which causes the signal for presence of water.
