SPT Series
Low Cost, Stainless Steel
Media Isolated Pressure
Sensors
DESCRIPTION
Honeywell’s SPT Series stainless steel pressure sensors are
designed for media that will not adversely attack 316L stainless
steel.
The back side metal tube is made from 304 stainless steel
which provides effective protection against most harsh
environments. The SPT Series is calibrated and compensated
for three styles of output: 4.0 mA to 20.0 mA (mA version); 1.0
Vdc to 5.0 Vdc (4 V version); and 0 mV to 100 mV (mV
version).
All versions feature a variety of pressure connections to allow
use in a wide range of OEM (Original Equipment Manufacturer)
equipment.
The SPT Series stainless steel devices are rugged and reliable
transducers for use in a wide variety of pressure sensing
applications where corrosive liquids and gases are monitored.

Notes:
1. Vacuum gage units (V option) allow you to pull a hard vacuum on the gage units. Vacuum gage parts are only available on the mV version in
15 psig through 500 psig. As sold, this package design is not submersible. In order to make the package submersible, the package needs to be
sealed.
2. The maximum pressure that can be applied without changing the transducer’s performance or accuracy.
3. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer case.

Notes:
1. Reference conditions (unless otherwise noted): TA = 25 °C [77 °F]; For SPTmA and SPT4V, Supply VS = 23.5 Vdc ±0.01 Vdc; for SPTmV:
VS = 10 Vdc.
2. Full-scale span (FSS) is the algebraic difference between the output voltage at full-scale positive pressure and the output at zero pressure. FSS
is ratiometric to the 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 operating 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. Common mode voltage as measure from output to ground.
