The K12 family
of optical level switches
are specially designed for use in level monitoring for controlling the oil in screw compressors
. They can be mounted directly on the crank case or the separator of screw compressors.
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 105 x 36 mm and have no moving parts.
They are typically used for lubricating oil level monitoring
, critical fluid level detection
on machine tools, chillers and other OEM equipment, monitoring refrigerant liquid levels
They have an operating temperature range of -40 to 125 deg C. There is a programmable timer
inside these K12 optical level switches that allows a delay time to be set for delaying the output switching.
The output modes are normally closed in presence of liquids and open in air or vice versa. The AC output current is up to 200mA depending on model.
It combines the 90-230 VAC Power Supply with the high temperature resistance (up to 125°C) and a variety of possible threads.
The K12 optical 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.
The K12 family of optical level switches have a detection accuracy of +/- 2 mm.
