2. Prepare the sealing of the connection:
- If the transmitter has a parallel ISO G1/2" thread or UNF
3/4"-16 thread, place the sealing ring at the base of the
thread. Always use a new sealing ring; do not re-use a
previously installed one.
- If the transmitter has an NPT 1/2" thread, do not use the
sealing ring. Instead, apply PTFE tape or suitable paste
sealant to the thread. Follow the application instructions of
the sealant.
3. Make sure that the threads on the mounting point are of the correct
type, and fasten the transmitter to the measurement point. Use your
hands to turn the probe until it feels tight. Do not use force at this
point, and check that the sealing ring (if used) remains centered.
