Hastelloy membrane Silicon pressure sensor
Introduction
SMP2080 Hastelloy membrane siicon pressure sensor core has the same
shape, assembly size and sealing methods with foreign mainstream
similar products, can be directly replaced. Each product's
production has adopted a strict aging, screening and testing
processes, to ensure excellent quality and high reliability.This
series of products can be reliably used in hydraulic systems,
industrial process control and other application.
