7.5 Pressure Compensation when using a Relative Pressure Sensor

A Goretex diaphram is used to compensate for the atmospheric pressure under the

IP 65 Protection Method.

A special cable with capillaries for relative pressurization is used for

Ingress Protection IP 67.

When connecting the clamps ’L+’ and ’I’ the safety-related nominal values

(See chapter 6.7) must be observed.

Only approved intrinsically safe ammeters may be connected to the test

circuit between the clamps ’L+’ and ’I’.

The internal resistance of the multimeter must be < 100

Ω.

The unit must be properly grounded in order to guarantee EMC resistance.
