Custom Sensors and Technologies (CST) product story
Edited by the Engineeringtalk editorial team

The sense element is based upon Kavlico's TiON (titanium oxynitride) thin-film technology, which is capable of withstanding high media temperatures.
Kavlico, a global business unit of Custom Sensors and Technologies (CST), has released a combined pressure and temperature sensor for use with the R744 (C02) natural refrigerant for pressure and temperature sensing in mobile air conditioning systems.
By replacing ozone depleting or global warming refrigerants with R744, global greenhouse gas emissions will be reduced significantly.
This rugged, low-cost sensor has a 17-4 PH hermetically sealed stainless housing.
The sense element is based upon Kavlico's TiON (titanium oxynitride) thin film technology, which is capable of withstanding high media temperatures.
The sensor's has an operating pressure range of 0 to 150bar with a proof pressure of 210bar and a burst pressure of 320bar.
The operating process media temperature range is -40 to +180C, and the ambient operating temperature is -40 to +135C.
Highly stable and accurate, the sensor can be specified with either an analogue, SPI, LIN2.0 or CANbus output.
The sensor tolerates high-vibration environments and has built-in reverse polarity protection as well as extremely good overvoltage protection.
The metal injection moulded (MIM) design allows a reduced package size that is light and easy to install.
The sensor does not use an external probe for measuring temperature.
The RoHS-compliant sensor meets the EU directives for electrical and electronic equipment.
