Pressure Sensor with Excellent Media Compatibility for Use in Extreme Temperature Conditions

Sensortechnics' piezoresistive 40PC series from Honeywell now offers gauge pressure measurement in a wide pressure range from 50 mm Hg to 500 psi (67 mbar to 35 bar). The sensors feature a 0.5…4.5 V amplified output signal providing a direct interface to an A/D input on a controller. The 40PC is built in a miniature 6-pin DIP package which saves critical board space and can be easily mounted. The fully calibrated and temperature compensated sensor is very robust, covering a wide range of temperature extremes from –45…125 °C. Additionally, the 40PC series is compatible with a broad array of gaseous and liquid media, from dry air and water to refrigerant coolants, engine fuel and oil. Important features of the 40PC series are:

• Wide pressure ranges from 50 mm Hg to 500 psi (67 mbar to 35 bar)
• (Vacuum) gauge and bi-directional gauge pressure measurement
• 0.5…4.5 V amplified output signal
• Miniature 6-pin DIP package
• Fully calibrated and temperature compensated from –45…125 °C
• Excellent compatibility with gaseous and liquid media

Typical applications include level control, environmental and medical applications and industrial and analytical instrumentation.
