1. Installation
The transmitter is available in three versions: a panel mount version, an integral (pipe mount) version, and a universal assembly for
installation near the sensor.
1.1 Panel Installation
The Panel Mounting kits are supplied with the hardware to
install instrumentation into panels and maintain a NEMA 4X
seal.
1. Punch out panel and de-burr edges. Recommended
clearance on all sides between instruments is 1 inch.
2. Place gasket on instrument, and install in panel.
3. Slide mounting bracket over back of instrument until
quick-clips snap into latches on side of instrument.
4. Connect wires to terminals.
5. To remove, secure instrument temporarily with tape from
front or grip from rear of instrument. DO NOT RELEASE.
Press quick-clips outward and remove.
1.2 Integral Assembly (3-8051)
1. Punch out conduit ports if necessary.
2. Connect sensor to integral adapter. Push and twist-lock
integral adapter to conduit base and secure with locking
ring and screw.
3. Mount unit in pipe. Route cable through cable gland and
connect to transmitter.
4. Close unit and secure. Seal cable entry.
1.3 Universal Assembly (3-8050)
1. Install transmitter base
2. Connect wires to transmitter.
3. Close unit and secure with push and twist lock.
Seal cable entry.
