Description:
ZERF-B3000 use the foreign famous brands’ silicon-on-sapphire pressure sensor with high-precision and high stability, by using the back-end amplifier circuit with high reliability, to convert the pressure signal of measured medium into a standard electrical signal output. The overall structure of the series without isolating diaphragm and intermediary liquid, the measured medium contact with titanium alloy diaphragm directly, with the characteristics of corrosion resistance, abrasion resistance, minimal zero drift.
