Abstract

The invention relates to a shock-resistant ice-blockage resistant pressure transmitter, and the pressure transmitter comprises a substrate with a cavity, and a housing. One end of the housing is connected with the substrate through a thread. The housing and the substrate cooperate with each other to form an annular groove for accommodating a sealing ring. The sealing ring is clamped between the housing and the substrate through the annular groove, and a sensitive element is mutually extruded and fixed with the substrate through the housing. The other end of the housing is connected with a Hirschmann connector in a threaded connection mode. A shock-resistant ice-blockage resistant device is disposed between the cavity of the substrate and the sensitive element. The interior of the housing is provided with a circuit board. A lead of the sensitive element is connected with the circuit board through a wire. The circuit board is connected with the Hirschmann connector, and is disposed in an insulating bush in a mode of potting an organosilicone potting adhesive. The insulating bush is fixedly disposed in the housing in an interference fit manner. The Hirschmann connector is externally connected with a cable.

A kind of shock resistance anti-ice blocks up pressure transmitter
Technical field
The invention belongs to automation field, be specifically related to a kind of shock resistance anti-ice and block up pressure transmitter.
Background technology
Pressure transmitter is a kind of sensor the most commonly used in industrial practice, and it is widely used in various industry automatic control ring Border, relate to water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, boats and ships, Numerous industry such as lathe, pipeline.
Pressure transmitter mainly has capacitance pressure transmitter and diffused silicon pressure transmitter, ceramic pressure transmitter, answers Variant pressure transmitter etc..Pressure transmitter is divided into general pressure transmitter (0.001MPa~35MPa) according to pressure measurement scope With differential pressure transmitter (0~1.5kPa), negative pressure transmitter three kinds.
The Main Function of pressure transmitter passes to electronic equipment pressure signal, and then in its principle of Computer display pressure Be substantially: the mechanical signal of this for hydraulic pressure pressure is transformed into electric current (4~20mA) such electronic signal pressure and voltage or Size of current is linear, usually proportional relation.
Pressure transmitter is to be delivered on semiconductor silicon diaphragm by measured medium by measuring diaphragm, then passes through scale On Wheatstone bridge measure, when ambient pressure changes when, Wheatstone bridge can change accordingly, thus Measure pressure.
Present pressure transmitter in use, needs the pressure stability during guarantee all measurements, slowly becomes Change, and interiors of products can not block.This series products is limited by the impact of compression shock and low ambient temperature, it is impossible at water conservancy, water The fields such as electricity play one's part to the full.
In use, when equipment starts, manifold pressure can reach positive normal pressure in moment to existing pressure transmitter The several times of power, the directly infringement to damaging property of product.Liquid meanwhile, in the case of ambient temperature is too low, in pipeline Due to volumetric expansion after body icing, can cause local excessive pressure at interiors of products, product can be caused irreversible equally Damage.
Summary of the invention
Goal of the invention: the problem that the present invention is directed to the existence of above-mentioned prior art makes improvement, i.e. the invention discloses one Shock resistance anti-ice blocks up pressure transmitter, and it can solve the problem that pressure transmitter is made by the compression shock that some equipment produces on startup The damage become, and can reduce, at measured pressure medium, the destruction that pressure transmitter is produced after icing, to reach For a long time, the purpose of reliable and stable use.
Technical scheme: a kind of shock resistance anti-ice blocks up pressure transmitter, including having pedestal and the housing of cavity,
One end and the pedestal of housing are threaded connection, and described housing matches with described pedestal and forms a receiving sealing The annular groove of circle, described sealing ring is arranged between described housing and described pedestal by this annular groove, and sensing element leads to Crossing housing and pedestal mutually extrudes fixing, the mode that the other end of housing is threaded connection is connected with Hirschmann joint,
It is provided with shock resistance ice-plug resistance device between cavity and the described sensing element of pedestal,
The inside of described housing is provided with circuit board, and the lead-in wire of described sensing element is connected by wire with described circuit board, Described circuit board is connected with described Hirschmann joint,
