Reliable detection of any leaks is important. Production processes can be impaired by leaking liquids such as water. The leakage of hazardous liquids such as acid, ammonia or Galden can endanger people and machinery. Leakage sensors reliably monitor sumps, tanks, walls or floors for escaping liquids.
With the appropriate safety switchgear, the SQ-4 series meets the requirements for SIL3 / Category 4 / PLe!
Features
One- or two-stage detection (light wetting, full wetting)
Standard series for water
Chemical resistant series for acid, ammonia, Galden or fluorine
up to SIL3 / Category 4 / PLe!

for acid, ammonia, Galden or fluorine. PFA is resistant to almost all chemicals, has a high temperature resistance, a low coefficient of friction and is flame retardant.
The SQ4 series in combination with the corresponding safety switchgear fulfills the highest category 4 / SIL3 with PLe.
By means of the XIOT Cloud switch, the leakage application is easily communication-enabled and alerts autonomously about any leaks. without power supply!
Multi-stage
Two-stage SQ4 series system
There are two detectors on the underside of the sensor, one in the front and the other in the center.
When a small amount of liquid reaches the sensor, it is detected by the front detector as light wetting. As the amount of liquid increases, it reaches the center of the sensor and the second detector detects full wetting. In this way, a multi-level lick detection can be realized.
