K11 Level Switch. Metallic IR sensor
k11-level-switch-ir-sensorThe K11 family of level switches are suitable for high pressure applications like pressurized vessels, HVAC and refrigeration, motors etc. They have bodies made of stainless steel and sensor dome made of glass.
They are economical, dependable, and compact in size with overall dimensions of 59 x 27 mm and have no moving parts.

These level switches use infrared technology for their operation. They have an operating temperature range of -40 to 125 deg C.
There is a programmable timer inside these K11 level switches that allows a delay time to be set for delaying the output switching. The output modes are closed in presence of liquids and open in air or vice versa.
The AC / DC output current is up to 100mA depending on model.

The K11 level switches must not be installed close to any infrared sources.
The dome must be at least 50mm away from any reflective surface (for lower distances please directly contact us). These level switches have electronic protection against transient over voltage, and reverse polarity (for DC models). The K11 family of level switches have a detection accuracy of +/- 2 mm. They can withstand maximum pressure of 60 bars.
