WARNING
PERSONAL INJURY
DO NOT USE these
products as safety or
emergency stop devices or
in any other application
where failure of the product
could result in personal
injury.
Failure to comply with
these instructions could
result in death or serious
injury.
Honeywell’s stainless steel 19C, 19U, and 19 Vacuum Gage Series
sensors were developed for pressure applications that involve measurement
of hostile media in harsh environments compatible with 316 stainless steel.
The special Vacuum Gage Series sensors are specifically designed for
applications that can be exposed to vacuum.
The 19C Series are calibrated and temperature compensated. They are
available for use with either a constant voltage or current source. They
feature a variety of pressure connections to allow use in a wide range of
OEM (Original Equipment Manufacturer) equipment. The 19U Series is
uncompensated for applications that use their own specialized circuit
designs.
The 19C and 19U Series sensors are rugged and reliable transducers for
use in a wide variety of pressure sensing applications where corrosive
liquids or gases are monitored.

NOTES
1. Reference conditions (unless otherwise noted): TA = 25 °C [77 °F]; 19C Supply VS = 10 Vdc ±0.01 Vdc or
IS = 1.5 mA ±0.0015 mA; 19U Supply VS = 5 Vdc ±0.01 Vdc or I = 1.0 mA ±0.0015 mA
2. Full-scale span (FSS) is the algebraic difference between the output voltage at full-scale pressure and the output at zero
pressure. FSS is ratiometric to supply voltage.
3. Pressure non-linearity is based on best-fit straight line from zero to the full-scale pressure. Pressure hysteresis is the
maximum output difference at any point within the operation pressure range for increasing and decreasing pressure.
4. Maximum error band of the offset voltage or span over the compensated temperature range, relative to the 25 °C [77 °F]
reading.
5. Long-term stability over a six-month period.
6. Response time for a 0 psi to FSS pressure step change, 10 % to 90 % rise time.
9. Common mode voltage as measured from output to ground. For higher levels of common mode voltage, contact factory.
10. The error band resulting from a maximum deviation of a transducer’s output parameter (offset, span, or resistance) as
temperature is varied 25 °C [77 °F] to any other temperature within the specified range (0 °C to 82 °C [32 °F to 180 °F]).
This parameter is not 100 % tested and is guaranteed by process design and tested on a sample basis only.
Temperature coefficient of span is evaluated using a constant current source.
