K06 4-20 mA Level Switch. Metallic IR sensor
K06 4-20mA Metallic liquid level switchThe K06 family of level switches with 4-20mA output have bodies made of stainless steel and sensor dome made of glass.
They are economical, dependable, and compact in size with overall dimensions of 95 x 27 mm and have no moving parts.
They are suitable for harsh industrial environments involving extreme temperatures, pressures, vibration and shock.
These switches not only sense liquid level but also monitor the temperature of the liquid.

These level switches use infra red technology for their operation. They consist of an infrared emitter and an optical receiver.
They have an operating temperature range of -40 to 125 deg C. There is a programmable timer inside these K06 level switches that allows a delay time to be set for delaying the output switching.
The output mode is normally closed or open in air and the output current (DC or AC) is up to 100mA depending on model.
The 4-20 mA analogue output is proportionate to the temperature measured.

The K06 level switches with 4-20 mA output must not be installed close to any infra red sources.
The dome must be at least 50mm away from any reflective surface.
These level switches have electronic protection against transient over voltage, and reverse polarity.
The K06 family of level switches have a detection accuracy of +/- 2 mm.
They can withstand maximum pressure of 40 bars.
