3.1.4 Heat tracing
When using heat or steam tracing, exercise caution if PVC coating is added onto capillary,
as PVC coating should not be exposed to temperatures above 212 °F (100 °C) to avoid the
possibility of thermal breakdown.
Best practice for heat and steam tracing is to regulate the temperature slightly above the
maximum ambient temperature for a consistent result. To avoid accuracy effects and
thermal stress, the capillary should not be partially heated.
CAUTION
NEVER attempt to disconnect the seals or capillaries from the transmitter or loosen
bolts.
Doing so will result in loss of fill fluid and will void the product warranty.
Failing to recognize incorrect materials during installation may cause process leaks, which
can result in damage to the diaphragm seal system or death and/or serious injury to
personnel. Proper wetted material is required for specific process materials.
