IN Brief:
- Mouser is now stocking TE Connectivity / Measurement Specialties 8XH media-isolated pressure sensors.
- The sensors combine a MEMS die, ASIC, and passive components inside an oil-filled isolated cavity.
- Factory calibration and digital output support precision pressure measurement without field calibration.
TE Connectivity / Measurement Specialties 8XH high-accuracy media-isolated pressure sensors are now available through Mouser Electronics.
The 8XH family is designed to deliver system-level precision without field calibration, targeting semiconductor equipment, process automation, medical devices, OEM IoT systems, and analytical instrumentation. The sensors combine a MEMS die, ASIC, and passive components inside an isolated oil-filled cavity.
The architecture uses the MEMS die bridge resistance to measure both temperature and pressure in the same thermal environment, giving the device local temperature information for compensation. That supports initial accuracy and EMC performance in equipment where pressure readings have to remain stable across changing operating conditions.
The family supports gauge, vacuum gauge, and absolute pressure measurements across a range from 5psi to 1500psi. Output options include amplified analogue and digital communication, with I²C support and selectable update modes. The sensors are factory calibrated and packaged for integration into designs where pressure media must be isolated from the silicon sensing element.
Media isolation is a practical requirement in many industrial and medical systems because fluids, gases, cleaning agents, process materials, and biological media may be incompatible with exposed silicon sensors. By placing the sensing die behind a diaphragm and oil-filled cavity, the sensor can measure the mechanical effect of the media while protecting the sensitive electronics.
That protection has to be balanced against accuracy, response, package size, and cost. The diaphragm, fill fluid, mechanical mounting, thermal path, and compensation algorithm all shape the final measurement. A media-isolated device is therefore a mechanical and electrical measurement system, not simply a conventional pressure sensor with a barrier added.
Application-specific sensing requirements are also evident in Cyntec’s BJB sensing portfolio, where measurement capability is closely tied to packaging, operating conditions, and industrial deployment. TE’s 8XH availability through Mouser sits in that same practical design territory, where component behaviour inside equipment is more important than isolated sensor specifications.
Semiconductor equipment can use pressure measurement in vacuum handling, gas delivery, cooling, fluid control, and process monitoring. Those systems are sensitive to contamination, drift, and downtime, making calibrated, media-compatible devices useful where repeatability is required over long operating cycles.
Medical equipment adds compact packaging, cleaning, fluid contact, pressure variation, documentation, and reliability requirements. OEM IoT systems introduce distributed deployment constraints, especially when pressure sensing is placed in remote assets where field calibration is expensive or impractical.
The I²C option gives designers a direct digital route into microcontroller-based systems, while amplified analogue output supports established signal-chain architectures. That flexibility is useful because pressure sensors often have to fit into existing control platforms rather than force a redesign around one interface.
Factory calibration reduces the burden of precision sensing in production and maintenance. Field calibration adds time, equipment, documentation, and operator dependency, and in distributed systems it can become a recurring service cost. Building compensation into the device can reduce variation between units and shorten integration.
The broader trend in sensing is toward more complete sensor modules, where MEMS elements, analogue conditioning, digital compensation, packaging, and interface options are brought together. TE’s 8XH family adds another stocked route to calibrated media-isolated pressure measurement, with Mouser improving access for prototype and production builds in equipment where pressure data is part of control, safety, or process quality.
