It is possible to supply the device with an external voltage source. This is usually the
case in applications where it is possible to obtain the supply voltage from a separate
supply unit (e.g. enclosure).
The nominal value of the supply voltage is 24 V DC. The TPK should be supplied
with a stabilised, short-circuit protected and surge-protected voltage source.
The power source of the pressure transducer must be from an energy-limited source
(10 A max./30 V max.) and be safely separated from the mains. See EN 61010-1,
paragraph 9.4.
