  SLP33 Series Compensated Amplified Small Gage Pressure Sensor (DIP Version). Pressure sensor media includes water, liquid and other fluid   Senphire offers high value added products for sensing applications. We term our offerings the Sapphire of sensing
Grey Blank  
The SLP 33 Series are fully compensated and amplified pressure sensors with a pressure port ( nipple ). With its small size and low pin count the Series delivers excellent value when a small gage pressure sensor is required. Ordering options include negative pressure ( vacuum ) or dual polarity (-xx to +xx psi) pressure ranges.

SLP 33 Series

Based on Senphire’s proprietary sensor platform the SLP 33 Series incorporates a silicon MEMs pressure sensor with the latest ASIC technology. The series incorporates multi-order digital compensation of offset, span, non-linearity and temperature effects with compensation coefficients stored in an on-board EEPROM.

The SLP 33 Series is designed to utilize the back side of the MEMs pressure sensor to sense the pressure. This way the sensitive piezoresistors are isolated from the pressure media allowing it to be used in harsh environments such as high humidity, water, liquid and different types of fluid.

The Series also presents a small compensated amplified pressure sensor and comes in a surface mount version for applications with limited space. It is one of our most versatile sensors and has found its way into vacuum pressure gauges, water level measurement and many more.

The SLP 33 Series can be specified with pressure ranges from 0.3-100 psi.
