A variable dimensions differential pressure transducer comprises a shell, an outward flange arranged at lower end of the shell, a connection box arranged on a lateral side of the shell, a connecting screw-thread and an O-shaped ring arranged at upper end of the shell, a discharging valve for air and liquid arranged at the outward flange, wherein two inner flanges arranged at the outward flange are perpendicular to the outward flange, a sensing device is arranged between the two inner flanges and sealed by welding, an O-shaped collar is arranged on the outside of the middle portion of the discharging valve for air and liquid, while a sealing gasket is arranged at inside. The variable dimensions differential pressure transducer is capable of preventing pinch stress from influencing on output signal of conventional differential pressure transducer, thereby has the advantages of reliable performance, small volume, low cost, convenient using, flexible production and increasing variety.
Description
technical field [0001] The invention relates to a differential pressure transmitter, in particular to a scale-changeable differential pressure transmitter, which belongs to the technical field of industrial automation instruments. Background technique [0002] The differential pressure transmitter is mainly used to measure the differential pressure, pressure, liquid level and density of liquid, gas or steam, and then convert it into a 4~20mA DC signal output. [0003] Differential pressure transmitters include three types: DP type (basic type), HP type (high static pressure) and DR type (micro differential pressure). The combination of the above three types of transmitters and the intelligent amplifier board can constitute an intelligent differential pressure transmitter, which can communicate with each other through a hand-held device conforming to the HART protocol for setting and monitoring. [0004] HP type high static pressure differential pressure transmitter is a dif...
