5 INSTALLATION
NOTES: Follow all Notes on Safety in Section 2 during installation.
5.1 GENERAL MOUNTING INFORMATION
Do not remove the protective cap on the SPX until ready to install.
Before mounting the SPX, check the process connection carefully. The SPX must only be mounted in
process connections that satisfy the requirements below. A process connection that does not satisfy
these requirements can damage the transmitter.
Insure the process connection is clear of any debris and is machined to the proper dimensions. In
applications involving high temperature operation and/or repeated thermal cycling a good high quality
anti-seize compound should be applied to the threaded surfaces.
Install unit into the process connection (Do NOT torque transmitter into the hole at this time!). Allow
time for the transmitter snout temperature to equalize to the process temperature. This will help
eliminate thread galling and ease removal later. There should be NO pressure applied at this time.
Always use a torque wrench applied to the designated wrench flats while screwing the transmitter in
and out. Do not apply the tool to the housing or housing/sensor connection.
After temperatures have equalized tighten transmitter into process connection.
When removing the SPX, carefully clean the diaphragm of the transmitter with a soft cloth while the
medium is still malleable.
Always remove the SPX prior to cleaning the machine with abrasives or steel wire brushes. Also, do not
clean the SPX with hard objects, such as a screwdriver, a wire brush, etc. This will possibly damage the
transmitter.
Burn Hazard! The SPX can be very hot when removed. WEAR PROTECTIVE GLOVES!
Careful attention should be paid to correctly machine the mounting port. Failure to use
the recommended mounting port may result in erroneous pressure measurement, difficult transducer
removal, premature sensor failure, process fluid leaks, and personnel hazard.
5.2 ELECTRICAL CONNECTION
Connect power to the transmitter. For conduit output configuration, Red wire is Sig+/Exc +, Black wire is
Sig-/Exc-, Green wire is Ground. For a 6 pin connector version, Pin A is Sig+/Exc+ and pin B is Sig-/Exc-.
Insure proper loop supply voltage is applied to transmitter.
