Description
Technical field
The present invention relates to pressure transmitter field, in particular it relates to a kind of explosion-proof wireless pressure pick-up device.
Background technology
In use, its safety is particularly significant for pressure transmitter, especially has dangerous medium in measurement
In environment, the security performance of instrument must obtain the concern highlighted.And in the design of pressure transmitter, its wiring and electronics unit
The design of part circuit is paying close attention to a little of Explosion-proof Design.Existing explosion-proof wireless pressure transmitter, it solves the problems referred to above
The method used is that signal processing module uses modularized design and wiring and electronic circuit are arranged on the most independent air chamber
In, but, it is arranged on being wired to electronic circuit in different air chambers, due to the setting of wiring so that air chamber exists sealing and asks
Topic.
Summary of the invention
The present invention is to solve that above-mentioned technical problem provides a kind of explosion-proof wireless pressure pick-up device, its security seal coefficient
High.
The present invention solves the problems referred to above and be the technical scheme is that
A kind of explosion-proof wireless pressure pick-up device, including pressure transducer with for the signal of processing pressure sensor output signal
Processing module, described signal processing module includes signal conversion unit and signal measurement output unit, described signal conversion unit,
Signal measurement output unit lays respectively in two the first adjacent air chambers, the second air chamber, and described first air chamber, the second air chamber are identical
Sidewall on be provided with perforation, be provided with the connection strap of conduction in described perforation, the hole wall of described connection strap and perforation
Between insulated enclosure layer is set, the two ends of described connection strap are single by wiring and signal conversion unit, signal measurement output respectively
Unit is connected, and the two ends of described connection strap lay respectively in the first air chamber, the second air chamber.The present invention is on the basis of existing technology
Improve, i.e. bore a hole on the sidewall that the first air chamber, the second air chamber are identical, connection strap is set in perforation, utilizes connection strap
The signal realizing signal conversion unit and signal measurement output unit connects, and connection strap is conductor material, and sidewall is the most also adopted
Preparing with metal material, the hole wall of connection strap with perforation is cut off by insulated enclosure layer, has both enhanced the sealing between air chamber, also
Avoid the electric conductivity of sidewall to the impact of signal between signal conversion unit and signal measurement output unit.Signal conversion unit
Realizing telecommunications by wiring with connection strap respectively with signal measurement output unit to be connected, connected mode typically uses electric welding mode,
The two ends of connection strap should not be positioned at perforation, if the two ends of connection strap are positioned at perforation, when electric welding connects wiring with connection strap, and weldering
Insulated enclosure layer is easily damaged by stannum, thus destroys the insulated enclosure performance of insulated enclosure layer, uses this structure, although insulation
The thickness of sealant arranges sufficiently large avoiding and is destroyed, but, when the thickness of insulated enclosure layer is the thickest, although its insulating properties is not
Can be affected, but, thickness its sealing the thickest is the poorest, therefore the two ends of connection strap lay respectively at the first air chamber, the second gas
In in room, also allow for the welding of butted line.
As preferably, for the ease of the welding of butted line, the two ends of described connection strap are provided with groove, described wiring card
In groove.
As preferably, described connection strap is copper bar.
As preferably, the sidewall both sides that described first air chamber, the second air chamber are identical are provided with wiring fixture.
To sum up, the invention has the beneficial effects as follows:
Bore a hole on the sidewall identical at the first air chamber, the second air chamber of the present invention, connection strap is set in perforation, utilizes connection strap
The signal realizing signal conversion unit and signal measurement output unit connects, and its security seal coefficient is high.
