PPT80 High Temperature Low Pressure Low Profile Sensor

Low-Cost OEM, Low-profile, Low Pressure Sensor with Analog output

The PPT80 is a pressure transducer manufactured for a high operating temperature range for the most challenging of applications.  This silicon pressure transducer  was designed for industrial and commercial applications.  The stainless steel design and high temperature analog component selection allows the sensor to be used in high temperature applications.

The PPT80 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).

The  design is simple, cost effective, and proves reliable for OEM customers.  Please  contact us for Custom design availability.

Package

The one piece body design is made of Brass (SS316L option), 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 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.

Pressure port

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.

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 Brass) , PPS, and SIO2.

Pressure ranges

Standard pressure ranges are 15, 50, 100, 150, 200, and 300 psi in absolute and gage. Custom pressure ranges are available for OEM customers.
