MODEL P110C Absolute or Sealed Pressure Transducer
The Model P110C variable reluctance absolute or sealed pressure transducer is
designed specifically for the petro-chemical industry. All welded construction reduces
long term drift and hysteresis and increases accuracy. The pressure cavity is designed
with no entrapment areas to facilitate cleaning. This unit features Tavis Corporations
highly stable, reliable, accurate 4 to 20 mA electronics.

*Static error band is defined as
the maximum allowed deviation
froma best fit straight line which
minimizes errors due to non-linearity,
hysteresis, resolution and
repeatability.
*Temperature error is defined as
the maximum allowed deviation
froma best fit straight line which
minimizes errors due to temperature
over the range of 30 F to
130 F.
