SES TRANSMITTER
A smart end seal transmitter with an RTD (SES-RTD) for temperature and continuity
sensing is included on the pipe sculpture of the PLI Module Demo Unit. The SES-RTD
transmitter (typically placed at the end of a heater circuit) replaces the end seal and
conventional RTD sensing elements and associated wiring, sending temperature and
continuity information to the central microprocessor-based controller. The SES transmitter
requires a NGC-30 UIT and a power line carrier interface module (PLI module). On/Off
control of the heating cable via contactors in the NGC-30 is optional if monitoring only is
desired. Up to 127 strategically placed SES transmitters communicate with one PLI
module (one PLI module per heat-tracing transformer).
SPC TRANSMITTER
A Smart Power Connector (SPC) is included on the pipe sculpture of the PLI Module
Demo Unit. The SPC transmitter serves as power connection kit and temperature sensing
device. The SPC transmitter provides power to the heating cable and replaces the power
junction box and conventional RTD sensing elements and associated wiring, sending
temperature information to the central microprocessor-based controller. The SPC
transmitter requires a NGC-30 UIT and a power line carrier interface module (PLI module).
On/Off control of the heating cable via contactors in the NGC-30 is optional if monitoring
only is desired. Up to 127 strategically placed SPC transmitters communicate with one PLI
module (one PLI module per heat-tracing transformer). Since the SPC transmitter was
installed at the beginning of the self regulating heating cable, it can be used for
temperature monitoring only. The SPC transmitter cannot be used for continuity
monitoring. The SPC transmitter is available on pipe or wall-mount options.
