Intended use
Model with Stainless Steel housing to be used in applications with a maximum pressure up to +25 bar.
The different models of optical level indicators are used to control the level in tanks and containers, normally of reduced dimensions, in which non-scaling and clean waters, oil, chemical products, etc. are used.
Function
The optical controllers bases their function on the reflection outline. There is a LED and a phototransistor inside the plastic housing of the sensor.
When there is no liquid covering the cupola, all the light from the LED is reflected to the phototransistor. When the level of liquid covers the cupola of the sensor, the reflection rate changes and some of the light is not reflected to the phototransistor and it activates the signal. When the liquid goes below the cupola, the signal switched back.
Mechanical connection
It is simple: The sensor is fixed in the tank or tube with the thread proccess connection G 3/8 ".
