19 mm Series
Low Cost, Stainless Steel,
Isolated Pressure Sensors
DESCRIPTION
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

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.
7. The maximum pressure that can be applied without changing the transducer’s performance or accuracy.
8. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer
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 1 mA constant current excitation source.
PHYSICAL DIMENSIONS (For reference only: mm [in].)
Package 1 (see note): Cell Package
Note:
Non-concentricity effects at the diaphragm weld area may cause runout of up to ±0.006 in between the upper and lower portions of the
sensor body. (It is recommended to use a counter bore to mate with this device to allow for this non-concentricity).
