You will have to provide a sealing element which corresponds
to the application.
Exceptions may be instruments with self-sealing threads (e.g. a
NPT-thread).
When mounting the instrument, ensure that the sealing faces of
the instrument and the measuring p o i n t a r e c l e a n a n d
undamaged.
Screw in or unscrew the instrument only via the flats using a
suitable tool and the prescribed torque. The appropriate torque
depends on the dimension of the process connection and on
the sealing element used (form/material). Do not use the case
as working surface for screwing in or unscrewing the
instrument.
When screwing the transmitter in, ensure that the threads are
not jammed.
If necessary, comply with instructions concerning threaded
holes and welding sockets.

5.3 Product Label (Example)
The METS-WTEx is screwed directly into the process via the process connection. A change in resistance of the
sensor element in the tip of the thermowell is transformed into an electrical standard signal by a measuring
amplifier. The signal changes proportional to the temperature and can be evaluated.
5.1 Function
5.2 Before Mounting
- Check if a fully assembled temperature sensor has been supplied.
- Inspect the measurement amplifier for possible transport damage. If transport damage is
detected, inform the transport company and supplier immediately.
- Keep the packaging, as it offers optimal protection during transportation.
- Ensure the process connection thread and the connection contacts are protected from damage.
The resistance thermometers are designed for being screw
fitted directly into the process. The insertion length, along
with the flow velocity and viscosity of the process media,
may reduce the maximum viable load of the thermowell.
