Description
This product is based on a glass micro-melting process, in which MEMS silicon strain gauges are permanently bonded onto a stainless steel elastomer through high-temperature sintering with special glass, replacing traditional organic adhesive bonding.
It is applied to various pressure measurement points in gasoline/diesel vehicles, hybrid vehicles, and new energy vehicles, providing real-time monitoring of system pressures such as engine oil, fuel common rail, refrigerant, brake, transmission hydraulic, SCR urea, and gas pressure reduction, and supplying critical signals for engine thermal management and power control.
Featuring an all-solid-state integrated structure, a high-temperature-resistant alloy sheath, and an automotive-grade connector, it has no creep and no aging failure, and can operate long-term in harsh working conditions involving wide temperature ranges, strong vibration, and corrosion.
