TRANSMITTER INSTALLATION
8.1 Transmitter Power Requirements
The AC version of the transmitter can accommodate an input voltage
of 100 – 240 volts AC, 50/60 Hz, and requires 25 watts of power.
The AC powered transmitter input power is fuse protected by two 1
amp, 250 volt, 5mm x 20mm fuses.
The DC version of the transmitter can accommodate an input voltage
of 18 – 36 volts DC and requires 25 watts of power.
The DC powered transmitter input power is fuse protected by two 3.15
amp, 250 volt, 5mm x 20mm fuses.
Only replace fuses with the fuse type indicated on the label inside of
the transmitter cover.
WARNING
Electrical shock hazard. Always disconnect power source prior
to removing fuses. Failure to remove power source may result
in injury or death.
WARNING
When explosive gases may be present, obtain hot work permit or
disconnect power source prior to opening cover. Failure to
remove power source may result in injury or death.
8.2 Transmitter Environmental Conditions
The transmitter operating temperature range is –4 ºF to 140 ºF (-20 ºC
to 60 ºC).
The NEMA 4X transmitter housing is suitable for operation in 0 –
100% relative humidity environments.
8.3 Transmitter Mounting Instructions
The transmitter is furnished with a Bulkhead (wall or panel surface
mount) Installation Kit. An optional Pipe Installation Kit is also
available.
The maximum sensor head to transmitter cable length is 300 feet.
Select an installation location that allows for easy and safe access to
the transmitter. Ensure the local ambient temperature range is within
the operating temperature limits of the transmitter. If possible, avoid
locations with extreme vibration and locations that are subject to
extreme water conditions (i.e. direct hose-down).
