19C Series 0 to 3psi to 0 to 500psi
Low Cost, Stainless Steel Isolated Pressure Sensors
General Description
The stainless steel 19C Series devices were developed for pressure applications that involve
measurement of hostile media in harsh environments. These sensors will accommodate any media
that will not adversely attack 316 stainless steel.
These 19mm sensors 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 equipment.
The 19C Series devices are rugged and reliable transducers for use in a wide variety of pressure
sensing applications where corrosive liquids or gases are monitored. Contact your local Invensys
representative or the Invensys factory for additional details.

=10 Vdc±0.01Vdc or I
S
=1.5 mA±0.0015mA; Ta=25°C.
Note 2:
Span is the algebraic difference between the output voltage at full scale pressure and the output at zero pressure.
Full Scale Span (FSS) is ratiometric to the supply voltage.
Note 3:
Linearity is based on best-fit straight line from the zero to the full scale pressure. Hysteresis is the maximum
output difference at any point within the operating pressure range for increasing and decreasing pressure.
Note 4:
Maximum error band of the offset voltage or span over the compensated temperature range, relative to the 25°C
reading.
Note 5:
Long term stability over a six month period.
Note 6:
Response time for a step change from the zero pressure to the full scale pressure.
Note 7:
The maximum pressure that can be applied without changing the transducer’s performance or accuracy.
Note 8:
The maximum pressure that can be applied to a transducer without rupture of either the sensing element or
transducer case.
Note 9:
Common Mode Voltage as measured from output to ground.
