Braze Connections: PT5-xxT Series
The Stainless Steel tube connection does not
require any wet rag during brazing. It is important
to consider the following subjects:
- Use of flux and silver rod having a minimum
of 30% silver.
Before
- Direct torch away from transmitter as shown in
Fig. 6. Max. body temperature: 120°C
Leakage Test:
• After completion of installation, a test pressure
must be carried out as follows:
- According to EN378 for systems which must
comply with European pressure equipment
directive 97/23/EC
- To maximum working pressure of system for
non European installations.
that all Wiring (Fig. 1):
For proper wiring use cable assembly (PT4-Mxx).
Allow enough space on top of pressure transmitter
to mount plug as shown in Fig. 4. The plug can be
mounted on pressure transmitter only in one
position Fig 1: (1).

extended beyond 6 m, system signal noise and EMC
must be verified by installer for proper operation.
Note 2: Signal line should not be installed parallel
with power lines to avoid electrical interference.
