Teklab Liquid Level sensors

EEx Level Switch. ATEX Metallic IR sensor

The sensor has been manufactured to achieve the ia intrinsically safety, and to work in potential explosive environment – IIC Group – in the T6 (85ºC) temperature class.
The device shall be mounted only by qualified and authorized persons.
Since the sensor primary use is in hazardous location, an appropriate intrinsically safe interface must be used and installed in strict accordance with this technical brochure. Failure to observe this warning could result in serious injury or damages.
