MSG9100 intelligent high-precision pressure transmitter

Product Features	Adopting imported ultra stable silicon piezoresistive sensor with 0.05% high precision, 20:1 wide range ratio, high stability and reliability, equipped with HART
	Communication function, with intrinsic safety, explosion-proof type, multiple process connection standards, and good temperature characteristics.
working principle	Using semiconductor planar process technology to fabricate resistance bridges on silicon wafers. The medium pressure causes the metal diaphragm to shift, and through
	The intermediate fluid transfers pressure to the resistance bridge circuit. The resistance bridge circuit will output pressure that is linearly related to the pressure signal when subjected to pressure
	The force signal is further processed by electronic components and converted into a standard signal output.

Instrument installation

On site adjustment

Customers can adjust the horizontal viewing angle direction of the die cast aluminum shell by adjusting the fastening mechanism according to the on-site installation requirements, so as to achieve the desired effect

Tables are more convenient for on-site observation and installation (see the left figure above)

When the top of the instrument housing is designed with zero and full range adjustment mechanisms (see the figure on the right) and analog electronic components are selected, they can be adjusted through

Place two potentiometers inside the adjustment mechanism to achieve on-site adjustment. When selecting intelligent electronic components, they are placed in the adjustment mechanism

Two non-contact secondary sensitive switches inside achieve on-site adjustment.
