Description
FST******4 intrinsic-safety pressure transmitter is a silicon MEMS
strain gauge sensor which is glass bonded to a stainless steel
diaphragm.
It avoids influences on product caused by temperature,
humidity, mechanical fatigue and medium, thus to improve its
longterm stability in
the industrial environment. Its pressure sensitive elements are
made of imported ***4PH stainless steel in an integrated way and a
high-
performance intrinsic-safety explosion-proof circuit identified by
relevant state authorities is installed inside with the explosion
grade of
Exdâ…¡CT6. Digital circuits capable of strong RFI & EMI
resistance and automatic temperature compensation are installed
inside the
transmitter, and the transmitter is featured with the strong
interference resistance, wide working temperature scope, and
longterm stability,
etc. The series products provide several optional pressure
connections and electric connections for customers.
