Oil Filled Waterproof Pressure Transducer
Introduction
waterproof pressure transducer is an isolated oil - filled pressure sensor core with high performance, low cost and small volume. It uses MEMS Silicon chip. Manufacturing of each sensor is a process with strict aging, screening and testing to ensure the excellent quality and high reliability.
This product has high anti-overload capacity and wide temperature range, it is widely used in automobiles, loading machinery, pumps, air conditioning and other occasions where have high requirements on small size and cost-effective.
