High accuracy pressure transducer from Kavlico


Source: InnoVista Sensors

Kavlico, a global business unit of Custom Sensors & Technologies (CST) has developed the P255 general purpose pressure sensor with advanced electronics for enhanced performance. The mixed-signal CMOS ASIC provides for improved EMI/RFI and accuracy specifications. Specifically designed for pressure measurements of 0–15 to 0–1000 PSIA/PSIG, the P255 is a robust device utilizing a ceramic diaphragm that can withstand exposure to a wide array of liquid and gaseous process media.

Excited by 5 Vdc, the P255 provides a linear amplified output of 0.5 to 4.5 Vdc that is proportional to pressure. The sensor has low power consumption, superior long-term stability, and excellent repeatability and hysteresis. Other significant features include over-voltage, reverse polarity, and short circuit protection.

The P255 has a 316 stainless steel housing and has an operating temperature range of -40° to +125°C. Due to the sensors high shock and vibration tolerance, it is well suited for applications such as:

* Hydraulic systems
* Refrigeration and HVAC systems
* Gas tank pressure monitoring
* Level measurements
* Coolant pressures
* Agricultural chemical equipment
* Marine systems
* Aggressive fluid measurements

The P255 is RoHS compliant and can be ordered in off-the-shelf designs or adapted to fit unique OEM application-specific requirements. A wide variety of electrical connector and pressure connection ports may be chosen to fit measurement criteria.
