High Temperature Low Pressure Sensor
The PPT81 is a high temperature low Pressure sensor manufactured for the most challenging of applications. This silicon pressure transducer was designed for industrial and commercial applications including automotive, energy and commercial applications. The stainless steel design and high temperature analog component selection allows the sensor to be used in high temperature environments.
The PPT81 series utilizes MEMS piezo-resistive sensors pressurized on the passive backside of the SS housing which has superior long term stability and accuracy (.15% Linearity). For a smaller size transducer with a low price point for OEMs check out our PPT7Y series.
The design is simple, cost effective, and proves reliable for OEM customers. Please contact us for Custom design availability.

The one piece body design is made of stainless steel (SS316L), which allows for easy manufacturability and long term stability. Automotive grade vibration proof design for engine mount.
The silicon MEMS pressure sensor element is mounted to a ceramic base and sealed into the SS housing. The selection of thermally capability materials reduce the mechanical stress on the sensor resulting in greater stability over time and temperature.
Additional stability is gained from factory stabilization of all sensors.
1/4” -18NPT and 1/8”-18NPT threads are standard SS fittings. Other port fittings such as 7/16-20UNF, and ¼” BSP are available for OEM customers.
The pressure port is tolerant to most media including but not limited to oil, air, gas, some corrosive media, and salt water.
When checking media capability, the wetted surface is composed of only stainless steel (316).
Standard pressure ranges are 50, 100, 150, 200, and 300 psi in absolute and gage. Custom pressure ranges are available for OEM customers.
