3 Mounting 3.1 Operating conditions Differential pressure can be measured in dry, non-ionizing and aggressive gases with this measuring instrument. It should not be installed near to sources of interference (transformers, signal sources, electric motors) or sources of heat. Tremors or vibrations at the mounting location can lead to measurement errors.
4 Electrical connection Only suitable qualified professionals are allowed to connect the pressure transmitters! Please comply with the regulations and safety requirements for electrical, weak current and power current installations, particularly taking into account pertinent national regulations, such as VDE 0100. The supply voltage must not be connected to output signal terminals! This would result in an instrument fault.
