Temperature table
1.
The unit should be powered by an intrinsically safe signal processor with [EEx ia IIB] or [EEx ia IIC] certification.
Temperature class

conditions and at the most unfavourable place.
•
method and the speed of filling or emptying of the tank should be selected in accordance with the medium properties.
•
the electronic circuitry of the probe is grounded. An equipotential network should be formed along the intrinsically safe circuit. Distance between the transmitter and the
intrinsically safe power supply (accommodated in the non -hazardous area) must not exceed 100 m.
