Abstract
The invention relates to corrosion-resistant pressure transmitter equipment, which comprises a pressure transmitter body, a flange base, an isolation diaphragm, a transition ring, a sealing pile, a fixing bolt, a rotary fixing shaft sleeve, a locking threaded through hole, an insulating sheath, a sealing layer and a circuit board, wherein the fixing bolt is arranged below the pressure transmitterbody, and the flange base is arranged under the fixing bolt; the pressure transmitter body is connected with the flange base by means of the fixing bolt; and the sealing pile is arranged in the transition ring, and the bottom end of the transition ring is connected with the sealing pile through argon arc welding. The corrosion-resistant pressure transmitter equipment is reasonable in structural design, can effectively protect the circuit board, effectively solves the problem that an existing circuit board is poor in corrosion resistance, and effectively improves the structural stability of allcomponents of the pressure transmitter by compressing and welding the flange base, the transition ring, the isolation diaphragm and the sealing pile into a whole through argon arc welding.
Description
technical field [0001] The invention relates to the field of pressure transmitters, in particular to corrosion-resistant pressure transmitter equipment. Background technique [0002] A pressure transmitter is a device that converts pressure into a pneumatic signal or an electric signal for control and remote transmission. It can convert the physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal to supply secondary instruments such as indicating alarms, recorders, regulators, etc. for measurement, indication and process adjustment; sewage treatment plants It is inseparable from the application of the pressure transmitter. Due to the strong corrosiveness of the sewage, and it contains a lot of chemical substances, if the measured sewage flows into the inside of the pressure transmitter, it is easy to cause damage to the internal circuit board of the pressure transmitter; To this end, the present application proposes ...
