Fig. 8: Overview of terminal connectors F012-P-(PB / PD / PX) and options.
SENSOR SUPPLY
Type PB / PD / PX - terminal 3: sensor supply 1.2V, 3.2V:
Terminal 3 provides a limited supply voltage of 3.2 V DC (coil signals 1.2V) for the signal output of
the flowmeter.
Note: This voltage MAY NOT be used to power the flowmeters electronics, converters etc, as it will
not provide adequate sustained power ! All energy used by the flowmeters pick-up will directly
influence the battery life-time (type PB). It is strongly advised to use a "zero power" pickup such as a
coil or reed-switch when operating without external power. It is possible to use some low power NPN
or PNP output signals, but the battery life time will be significantly reduced (consult your distributor).
Type PD - terminal 6: sensor supply 8.2V:
With this option, a basic but real sensor supply of max. 5mA@8.2V is available to power e.g. a
Namur sensor.
