Description
Technical field
The invention belongs to the corollary equipment of gas detection transducer, more particularly it relates to which a kind of be used for gas
Detect a kind of gas detection transducer with sensor hot plug design in transmitter.
Background technology
With developing rapidly for industry, the occasion of human contact's pernicious gas is more and more, thereby results in the mankind in itself
Harm it is also increasing, each intoxication accident, recognizing of making that people regain consciousness protects the mankind while developing industry
The importance of inherently safe.Therefore the protection that various pernicious gas alarms turn into essential in industry security production gradually is set
It is standby.The Sensor section of existing gas detection transducer, designed using flame proof.According to flame proof scene relevant safety regulations,
Forbid powered uncap.But because sensor has service life, it is necessary to regularly replace, if more emat sensor is, it is necessary to elder generation
Powered off to instrument.Instrument at the scene is the connected mode of power sources in parallel mostly, when to wherein any one instrument power-off, loop
Other instrument can be also de-energized simultaneously, stop dangerous monitoring.Therefore more emat sensor is cumbersome at the scene for the instrument of flame proof design,
Waste time and energy and be inconvenient.
The content of the invention
Power-off to occur when solving above-mentioned existing gas detection transducer more emat sensor stops dangerous monitoring and changed
The problem of cumbersome and inconvenient, the invention provides a kind of gas detection transducer with sensor hot plug design.
The technical solution adopted in the present invention is：
A kind of gas detection transducer with sensor hot plug design, including Transmitter body, in the transmitter
Main body is provided with master control cavity and sensor cavity, and the master control cavity is connected with the sensor cavity, in the master control
Governor circuit module is provided with cavity, safety barrier circuit is installed in the governor circuit module, set in the sensor cavity
There is sensor assembly, the governor circuit module is electrically connected with the sensor assembly and is that the sensor assembly is powered,
Intrinsically safe circuit is provided with the sensor assembly.
Further, the master control cavity is flame proof cavity.
Further, the junction of the sensor cavity and the Transmitter body is provided with sealing.
Further, the sealing is sealing ring
Had the advantages that using the invention described above technical scheme：Governor circuit module and sensor in the present invention
Module is all to use substantial safety-design, and scene has the condition that electric spark, high temperature etc. cause igniting in no instance,
The powered requirement uncapped in scene is realized, when finally allowing the instrument to change sensor assembly at the scene, can directly plug replacing,
Do not influence instrumentation while convenient and swift also persistently to measure and dangerous monitoring, avoid monitoring blank.
Brief description of the drawings

Intrinsically safe circuit 32 is provided with 31.
The master control cavity 2 that a kind of gas detection transducer with sensor hot plug design of the present invention designs in flame proof
It is interior to use the governor circuit module 21 with safety barrier circuit 22, the delivery of limiting sensor module 31, make sensor assembly
31 power supply reaches essential safety；The present invention is also to use substantial safety-design, sensor assembly in the part of sensor assembly 31
Intrinsically safe circuit 32 in 31 is used for controlling the capacitive load of circuit part and the size of inductive load in sensor assembly 31, makes it
Will not produce can cause the energy accumulation of electric spark or other ignition conditions, do not have enough energy and cause spark, high temperature
Etc. ignition condition, inherently reach anti-explosion safety grade.
From the foregoing, it will be observed that the present invention is to use substantial safety-design in governor circuit module 21 and sensor assembly 31, it is existing
Field has the condition that electric spark, high temperature etc. cause igniting in no instance, realizes the powered requirement uncapped in scene, finally
When allowing the instrument to change sensor assembly 31 at the scene, replacing can be directly plugged, does not influence instrument while convenient and swift also
Table equipment persistently measures and dangerous monitoring, avoids monitoring blank.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's
