1) Use PTFE tape or o'rings to seal the system.
2) Before installing, make sure the cable connections are
correct and that the line voltage is compatible with the
specifications of the equipment. Use reliable cables and
make sure that they are grounded. Shielded cables
prevent interference and changes in the eletronic signal,
protecting against false measurement output. Avoid
radio frequency interference as it may also cause false
signals and even create a possible malfunction of the
transmitter. When possible, keep hand held
communication equipment away from the SP transmitter.
3) Care should be taken to prevent deformities in the
membrane. You should also be careful not to touch or let
any other object touch the membrane of the sensor
during installation (this does not apply to the units with
ceramic sensing elements) . Any deformity to the surface
of the 316SS silicone filled membrane will damage the
sensor and impair its operation.
Transmitters with cable gland:
Tighten the cable gland as much as possible so that the
cable is securely in place and cannot be pulled through
the cable gland. This will help insure that no moisture is
able to infiltrate into the housing. Don´t forget to attach
the housing cover and tighten all three screws into
position so that there is no infiltration.
4) Protect the transmitter against rain and do not expose it
to excessive heat. Respect the working temperature and
the class protection specified for use.
5) Before installation, for security reasons, make sure the
tank or pipe is empty and without pressure.
6)
For transmitters with sealing:
Under no circunstances should you remove the
transmitter seal. Avoid flexing the membrane with your
hands and keep it protected until the installation.
