DP86
316L SS
Wet/Wet Differential
Low Pressure
DESCRIPTION
The DP86 differential pressure sensor is a double-sided, media compatible, piezoresistive silicon
pressure sensor packaged in a 316L stainless steel housing. The DP86 is designed for o-ring mounting. The
sensing package utilizes silicone oil to transfer pressure from the two 316L stainless steel diaphragms to a
single sensing element.
The DP86 is designed for high performance, low pressure applications where differential pressure
measurement is required. The stainless steel package makes it suitable for use in liquids and corrosive
environments.
Please refer to the DP86 uncompensated, non-silicone oil, constant current and constant voltage
(fittings and cable design) for more information on different features of the DP86.

Notes
1.
Measured at ambient.
2.
Best fit straight line
3.
Over the temperature range -20°C to +85°C (0°C to 50°C for 1psi, 0°C to 70°C for 5psi) with respect to 25°C.
4.
For high-end port, rated or 1000psi whichever is less; for low-end port, rated or 150psi whichever is less.
5.
The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer.
6.
Max temp for cable and connector is -20°C to +105°C.
7.
Between case and sensing element.
8.
Load resistance to reduce measurement errors due to output loading.
9.
At dry air.
