INSTALLATION
Connect power to the transmitter. For a 2 wire 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.
Make sure that the medium is in molten condition during transmitter removal. Removing the transmitter
while the medium is in solidified condition can damage the sensor diaphragm.
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.
Before reinstalling the SPX, ensure that the mounting hole is free from hardened plastic. A mounting
hole cleaning tool kit is available to aid in removing of the material. (Dynisco Part Number 200100 for
½-20, 200101 for M18 and 200102 for M10 ports.) A gauge plug to check the hole is included in this
kit.
ESD sensitive component. Electrostatic discharge may damage the PT. Take ESD
precautions.
Mounting and electrical connection of the SPX must be done by specialists with EMC
training, following all applicable regulations, and in

The most common causes of transducer damage are: installation in improperly
machined or plugged mounting holes and cold starts. The tip of the transducer
consists of a stainless steel diaphragm that must be protected from severe abrasives,
dents and scores.

The SPX must be removed with the melt in the molten condition. 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. 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.
