Abstract

The invention discloses a water pipe pressure transmitter. The water pipe pressure transmitter includes a pipe joint nozzle, a silicon chip strain gauge, an insulation pad and a transition pad, wherein the pipe joint nozzle includes a pipe joint end, a flange and a base, the pipe joint end is used for connecting a water pipe, the silicon chip strain gauge is arranged at the middle of an outer sideof the base, the insulation pad fits a side surface of the base, the flange is connected with the middle of the transition pad, and the transition pad is connected with a casing. The water pipe pressure transmitter is advantaged in that design is exquisite, the structure is compact, a problem of large volume of a traditional transmitter is solved, the water pipe pressure transmitter can be mounted in the narrow space environment, the application scope is expanded, instant abnormality in the monitoring process can be displayed by an indicating lamp, and field inspection is easier and more convenient.

Description

technical field [0001] The invention relates to a fire-fighting / water supply pipe measuring instrument, in particular to a water pipe pressure transmitter. Background technique [0002] Fire / water supply pipes are arranged in buildings or factories. In order to ensure the normal operation of the water pipes, it is necessary to monitor the water pressure of fire / water supply pipes at different points / sections. Such measuring instruments generally use pressure monitoring transmitters. As the existing traditional type transmitters in the market are more and more widely used, users have higher and higher demands on the accuracy, appearance and volume of sensors. Common pressure monitoring transmitters on the market can usually only know the pressure range in the water pipe by connecting the transmitter to the signal processing system, and cannot directly know the pressure in the water pipe from the transmitter. In addition, the common pressure monitoring transmitters on the mar...
