Intelligent pressure transmitter

Abstract

The invention discloses an intelligent pressure transmitter. The intelligent pressure transmitter comprises a device body and a heat preservation device which is arranged at the lower end of the device body, the heat preservation device is arranged in the device body through bolts, a line hole is formed in the front of the top of the device body and embedded in the device body, side covers are arranged on the left side and the right side of the device body and arranged on the device body through bolts, a support structure is arranged in the middle of the device body, and the support structureis welded to the device body. According to the intelligent pressure transmitter, a fixing ring is arranged on the outer side of the line hole, by means of the fixing ring, a power line interface is isolated from the internal structure, and rainwater or steam can be prevented from entering the device, so that an internal circuit is damaged; in addition, the problem that parts in the device make contact with air for a long time, and oxidation is caused can be prevented, and the problems that for existing design, a power line export end is poor in protective measures, and the internal circuit cannot be well protected are solved.

Description

technical field [0001] The invention relates to the technical field of pressure transmitters, in particular to an intelligent pressure transmitter. 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 physical pressure parameters such as gas and liquid felt by the load cell sensor into a standard electrical signal for supply Indicates secondary instruments such as alarms, recorders, and regulators for measurement, indication, and process adjustment. [0003] However, the existing protection measures for the outlet end of the power line of the pressure transmitter are poor, and the internal circuit cannot be well protected, and the device for cooling or heating the measurement medium uses a spiral tube, which has a simple structure and poor cooling effect , cannot meet the cooling requirements of modern high-speed equipment. In addition, the ex...

Problems solved by technology

[0003] However, the existing protection measures for the outlet end of the power line of the pressure transmitter are poor, and the internal circuit cannot be well protected, and the device for cooling or heating the measurement medium uses a spiral tube, which has a simple structure and poor cooling effect , cannot meet the cooling requirements of modern high-speed equipment. In addition, the existing pressure transmitter wiring is complicated and not simple enough, which may easily cause wires to be entangled with each other, causing potential safety hazards
