Description
Technical field
The utility model belongs to a kind of equipment for gas detect, is specifically related to a kind of differential pressure transmitter.
Background technology
At present, general its weak point of gasmetry differential pressure transmitter have pressure transducer do not have temperature compensation or compensation effect undesirable, cause its adaptive capacity to environment poor, when bidirection press measured by needs, be negative value in the output signal of negative pressure section pressure transducer, because traditional integrated two-wire system transformer chip is not as processed negative signal, can only adjust the bridge road of sensor in the case, reach the object of transmitter span shift, and be the situation of closed loop for sensor bridge circuit, this method of adjustment will certainly produce considerable influence to the temperature performance of sensor and stability, thus the overall performance of transmitter is deteriorated.
Utility model content
The purpose of this utility model is to provide a kind of differential pressure transmitter, to solve the deficiency existed in above-mentioned technology.
In order to achieve the above object, the technical scheme that the utility model adopts is:
A kind of differential pressure transmitter, by impulse screw, mounting flange, base, connect liquid lid, plug screw, sealing gasket, diaphragm seat and impulse joint and form, described impulse screw is positioned at the bottom centre position of base, the two ends of base are connected with mounting flange by bolt, connect the right-hand member that liquid lid connects base, plug screw connects the right side of base, and sealing gasket connects below plug screw, the bottom right side of diaphragm seat connection flange, the upper center position of impulse joint connection flange.
Described base and mounting flange are aluminum alloy material and make.
Described impulse joint is threaded spigot shape.
The utility model structure is simple, and easy to use, technology is reasonable.Transmitter has carried out temperature compensation, by force anti-interference, and usability is stablized, and impulse joint is threaded spigot shape, can be directly installed on measuring channel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of differential pressure transmitter, by impulse screw 1, mounting flange 2, base 3, connect liquid lid 4, plug screw 5, sealing gasket 6, diaphragm seat 7 and impulse joint 8 form, described impulse screw 1 is positioned at the bottom centre position of base 3, the two ends of base 3 are connected with mounting flange 2 by bolt, connect the right-hand member that liquid lid 4 connects base 3, plug screw 5 connects the right side of base 3, sealing gasket 6 connects below plug screw 5, the bottom right side of diaphragm seat 7 connection flange 2, the upper center position of impulse joint 8 connection flange 2, described base 3 is aluminum alloy material with mounting flange 2 and makes, described impulse joint 8 is threaded spigot shape.
