The sensor power supply and current signal share the same two-wire shielded cable. The sensor supply voltage should never
exceed 2
4
VDC. Always provide complete electrical and physical separation between the sensor supply circuit and the
main circuit.
The
Positive (+)
and
Negative (-)
terminals are for connection to a 24 VDC power supply or to a 4-20 mA loop power source. The
wire to the terminals can be extended up to 1,000 feet using 16-22 gauge shielded instrumentation wire
The sensor should be wired with shielded 2-conductor cable (16 to 22 AWG) to protect from electromagnetic interference. If
using a liquid tight connector, select a cable with an outer diameter that is designed to ensure an effective seal with the
connector [typically between 0.20" to 0.35" (5 to 9 mm)].
Wiring should always be done by a licensed electrician in accordance with federal, state, provincial and local codes.
Note :
Remember that the output voltage of the power supply can be lower under nominal load (with a sensor current of 20.5
mA or 22 mA) and/or with the addition of other instruments placed within the circuit. If voltage spikes or surges are expected,
adequate isolation protection must also be provided.
