The new PTE7100 and PTE7300 hermetic pressure sensors from Sensata Technologies are designed for industrial applications with mid and high-pressure ranges. These include hydraulics and pneumatics, mobile hydraulics and off-highway vehicles, pumps and compressors, air conditioning and refrigeration systems, plant engineering and automation. Based on Sensata’s Microfused Strain Gauge (MSG) with high accuracy, this series offers high burst strength and high shock and vibration performance.
Made in stainless-steel, the design comprises a hermetic port without using internal o-ring seals, which allows sensor compatibility with most media and use in harsh environments. Moreover, a snubber option is available to dampen pressure spikes from hammer and cavitation. The PTE7100 series offers a measuring range from 0-50 bar to 0-600 bar (0-725 to 0-8700 psi). Its mechanical shock rating is of up to 500g, its vibration of up to 30g (10…2000Hz) and the burst pressure is of ≥10X. The sensor includes a broad choice of highly customizable ports, connectors, and analog electrical outputs allowing for easy integration with existing systems in numerous industrial applications.
The PTE7300 series delivers an I²C digital output of both pressure and temperature. The series is available in a fully hermetic IP69K package developed for wet environments. This sensor features low power consumption for battery operation, fast response time, increased sensor diagnostics, and sensor communication integrity check using cyclic redundancy check (CRC). The CRC of the communication data is additional to the integrity check of the internal chip memory and enables users to validate 100% of the sensor output, providing an extra measure of data protection for the sensor. Furthermore, the product is REACH/RoHS/CE compliant and is suitable for drinking water safe applications.
