Introduction
SPT21 is piezo-resistive pressure transmitter, uses high stable and
reliable pressure sensor and special circuit board to produce
transmitter. This product is used for measure and control of water
system, petroleum, chemi-industry, electric power, hydrology and
flow pressure measure, etc.
