Installation and Mounting

Mechanical Installation:

Process connection: Threaded connections as specified (G1/2, NPT, etc.)

Recommended torque: 15–25 N·m for G1/2 connections

Seal with PTFE tape or appropriate thread sealant

Do not apply torque to the housing body — use the hex nut flat on the process connection

Orientation guidelines:

For liquid media: Slightly tilt the transmitter downward to prevent air pockets

For gas media: Slightly tilt upward to prevent liquid accumulation

For steam applications: Install a condensate pot to protect the diaphragm from direct high-temperature exposure

Electrical Installation:

Supply voltage: 10–30 VDC (24 VDC recommended)

Two-wire 4-20 mA loop connection

Use shielded twisted pair cable with single-ended grounding

Observe correct polarity at terminal connections

Detailed installation procedures are provided in the Endress+Hauser operating instructions (BA01271P).
