Azbil Corporation Installation
Model PTG71 / 72 - Smart Pressure Transmitter 2-13
2-4 : Installing ferrule-mount (sanitary type) transmitters (model
PTG__S,PTG__K,PTG__T)
Safety precautions
CAUTION
• After the Transmitter is installed, do not use it as a foothold or any other
improper purpose. Doing so may damage the equipment and/or result in physical
injury.
• Hitting the glass portion of the indicator with a tool may break the glass and
result in physical injury. Caution must be exercised for products equipped with a
digital indicator.
• Be careful when installing the Transmitter if the process fluid temperature is
high. The heat of the fluid and/or the heat radiated from the piping may raise the
surface temperature of the Transmitter very high.
Installation precaution
• When installing the Transmitter, position and secure the gasket so that it does
not protrude from where the Transmitter is connected to the process (where an
adapter flange is coupled to a connecting pipe). If the gasket sticks out, liquid
leakage or output error may result.
• Do not use the Transmitter under any other operating conditions than specified
in the product specifications (i.e., rated pressure, connection standard, rated
temperature, rated vibration and rated humidity). Using this product under
incorrect operating conditions may cause damage to the product and leakage that
could lead to a major accident.
• Wiring work in hazardous area should be performed carefully by following the
work methods specified in the explosion-protection guidelines.
• Properly ground the Transmitter. If it is not grounded or the ground is
inadequate, output error will occur. Not grounding the transmitter is a violation
of regulations. Be careful of your footing during installation. Always wear safety
shoes.
• Mounting procedure: Piping conditions differ depending on the process.
Liquid: Mount the nozzle in the pipe side and install the Transmitter sideways to
or to the downside of the nozzle so that no deposit is produced and the
gas generated returns to the process piping.
Gas: Mount the nozzle to the top or the side of the process pipe and install the
Transmitter side by side with or to the upper side of the nozzle so that the
process returns to the process piping.
Steam: Mount the nozzle on the pipe side and install the Transmitter at the
downside of the nozzle so that the condensed water collects in the conduit
piping.
