Design and thermal simulation analysis of high temperature molten salt pressure transmitter
Pressure transmitters are one of the most commonly used pressure sensors in industrial ap-plications and are widely used for flow,level,and pressure measurements.At present,the extreme work-ing temperature condition of the high-temperature resistant remote pressure transmitter at home and abroad is 370℃,and the measurement medium of the high-temperature molten salt pressure transmitter is NaCl molten salt with a certain corrosiveness with a melting point of 580℃.On the basis of the tradi-tional remote pressure transmitter,the structure of this high-temperature molten salt pressure transmitter is optimized,including the design of the transmitter body and the design of the remote transmission de-vice,as well as the circuit reliability design,and the feasibility of the design of this scheme is verified by thermal simulation analysis.Through simulation analysis,it is verified that the structural design of the scheme is feasible,and the heat resistance and heat dissipation effects are good,and it can be applied to the pressure measurement of high-temperature molten salt.
