The PPT89M (miniature pressure sensor) is a digital (I2C,SPI) pressure and temperature transducer manufactured for a high operating temperature range for the most challenging of applications. The unique design allows for temperature measurement of the media with fast-response time. This silicon pressure transducer was designed for industrial and commercial applications. The PPT89M Miniature High Accuracy Digital Pressure Transducer is a compact and highly precise pressure measurement device designed for applications where space is limited and high accuracy is essential.
This sensor is similar to but even better than the TE EPB Miniature Pressure Transducer.
The PPT89M series utilizes MEMS piezo-resistive sensors pressurized on the passive backside of the SS housing which has superior long-term stability and accuracy (.25%Linearity).

Media
The pressure port is tolerant to most media including but not limited to oil, air, gas, some corrosive media, and salt water.
Wetted parts
When checking media capability, the wetted surface is composed of only stainless steel (316 or 17-4).
Pressure ranges
Standard pressure ranges are 100, 300, 500, 1000, 1500, 3000, 5000, and 10,000 psi in absolute and gage. Custom pressure ranges are available for OEM customers.
Package
The one-piece body design is made of stainless steel (SS316L or 17-4PH), which allows for easy manufacturability and long-term stability. Automotive grade vibration proof design for engine mount.
Stability
The silicon MEMS pressure sensor element is media isolated and hermetically 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.
Pressure port
1/4″ -18NPT and 1/8″ -18NPT threads are standard SS fittings. Other port fittings such as 7/16-20UNF, and 1/4″ BSP are available for OEM customers.
