K25 4-20 mA Level Switch. Metallic IR sensor |
![]() 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 90 x 36 mm and have no moving parts. They not only sense the level but also measure the temperature of the liquid via 4-20mA output. 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 K25 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 DC digital output current is up to 50mA depending on model and the temperature output is 4-20mA analogue current output These level switches must not be installed close to any infrared sources. The dome must be at least 50mm away from any reflective surface (directly contact us for lower distance installations). They have electronic protection against transient over voltage and reverse polarity. The K25 optical level switches have a detection accuracy of +/- 2 mm. They can withstand maximum pressure of 150 bars. Technical Data of the InstrumentOperation mode : Detect liquid presence with contact Temperature Reference
