6.2.3 Setting up a voltage supply
The power supply for the pressure transmitter must be made via an energy-limited electrical circuit in accordance with
section 9.3 of UL/EN/IEC 61010-1, or an LPS to UL/EN/IEC 60950-1, or (for North America) class 2 in accordance with
UL1310/UL1585 (NEC or CEC). The power supply must be suitable for operation above 2,000 m should the pressure
transmitter be used at this altitude.
■ Power supply:
DC 10 ... 30 V
■ Load in Ω
≤ (power supply - 10 V) / 0.02 A - (cable length in m x 0.14 Ω)
6.3 Functional check
The output signal must be proportional to the prevailing pressure. If this is not the case, this may indicate a damaged
diaphragm. In this case, see chapter 8 “Faults”.
7. Maintenance and cleaning
7.1 Maintenance
This submersible pressure transmitter is maintenance-free.
Repairs must only be carried out by the manufacturer.
