Abstract
The utility model relates to a wireless transmission diaphragm measuring pressure temperature sensor, the technical problem that solve are the wireless transmission who realizes miniaturization of pressure temperature sensor and signal, belong to automation instrument and measure technical field. Its characterized in that: the diaphragm isolator includes isolation diaphragm, mounting flange, and isolation diaphragm arranges in mounting flange measures the center of face, and the working solution has been put in the inside isolation diaphragm's of mounting flange the inboard chamber that holds for pressure transmission, the coupling that some centre bores and mounting flange were put to TPMS automobile tire atmospheric pressure monitor sensor's measurement face passes through the threaded connection fastening. Actively the effect is, refers to the TPMS technique, utilizes current ripe diaphragm -seal pressure gauge technique, changes slightly original structure, realizes pressure and temperature parameters measuring device's the miniaturization and the wireless transmission of signal. Accomplish that earlier stage investment is low, signal transmission rises wirelessly from wired, enlarges the product application scope.
Description
Technical field
The utility model relates to a kind of wireless transmission barrier film and measures pressure/temperature sensor, and the remote real-time monitoring being particularly useful for pressure and temperature parameter is measured, and belongs to instrument and meter for automation field of measuring technique.
Background technology
Intelligent wireless network WIA(WirelessNetworksforAutomation) technology, released by Chinese Academy of Sciences's Shenyang Institute of Automation, be a kind of ad hoc multihop wireless sensor network technology, be applicable to Industry Control and factory automation processes control field.For the wireless pressure transmitter of building intelligent field development & production, industrial system can not be met again in the high requirement in pressure and temperature parameter measurement field in the miniaturization of products, cost, performance, technological operation maturation and all many-sides of simplicity.In automobile industry, TPMS (automobile tire pressure monitoring immediate system) technology is outshined othersOne branch of the tree is particularly thriving, TPMS immediate system utilizes to be arranged on the next direct measuring wheel air pressure temperature of each tire upward pressure temperature sensor, and data are sent by a kind of wireless mode.But the measured medium that TPMS automobile tire pressure monitoring sensor is suitable for is clean air, but often measure burn into high temperature, high viscosity, easily crystallization in various industrial occasions, easily solidify, have the pressure medium of solid floating material, so if do not added transformation, its use occasion has limitation.
At present, known for industrial system site pressure and temperature parameter measurement mechanism, supported the use by the converter (display) of sensor and pulpit, the pressure/that in-site measurement obtains by sensor or temperature parameter, by wire transmission to converter, export 0 ~ 10mADC/ or 4 ~ 20mADC, shown by digital displaying meter, the pointer-type display also having employing more traditional.Matching instrument is many, cost is high, volume is large, use is inconvenient.
For avoiding above-mentioned shortcoming, adopt the wireless transmission barrier film measurement mechanism being made up of a system barrier film isolator and TPMS automobile tire pressure monitoring sensor, realizing the miniaturization of pressure and temperature parameter measuring apparatus and the wireless transmission of signal, is that scientific and technical personnel constantly explore the direction of effort in the industry.
Summary of the invention
The purpose of this utility model is, provides a kind of wireless transmission barrier film to measure pressure/temperature sensor, uses for reference TPMS technology, realize the wireless transmission of pressure/temperature sensor miniaturization and signal.
For achieving the above object, the technical scheme taked is: pressure/temperature sensor measured by a kind of wireless transmission barrier film, comprise TPMS automobile tire pressure monitoring sensor and barrier film isolator, it is characterized in that: described barrier film isolator comprises isolation diaphragm, mounting flange, described isolation diaphragm is placed in the center of described mounting flange measuring surface, the inboard cavity volume of the inner described isolation diaphragm of described mounting flange is equipped with working fluid, for pressure transmission; The pipe adapter of the center pit that the measuring surface of described TPMS automobile tire pressure monitoring sensor is equipped with and described mounting flange is threaded connection fastening.
Good effect of the present utility model is, uses for reference TPMS technology, utilizes the diaphragm technology of existing maturation, slightly change original structure, can expand range of application, be applicable in various industrial system pressure tester.Realize the miniaturization of pressure and temperature parameter measuring apparatus and the wireless transmission of signal.Accomplish that front-end investment is low, Signal transmissions is raised to wireless from wired, realizes product up-gradation.
Accompanying drawing explanation
Below with reference to the accompanying drawings illustrate and embodiment the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Fig. 2 is utility model works functional block diagram.
In figure, 1-TPMS automobile tire pressure monitoring sensor; 2-mounting flange; 3-working fluid; 4-isolation diaphragm.
Embodiment
Fig. 1 is the utility model structural representation; As shown in the figure, pressure/temperature sensor measured by a kind of wireless transmission barrier film, comprise TPMS automobile tire pressure monitoring sensor 1 and barrier film isolator, it is characterized in that: described barrier film isolator comprises isolation diaphragm 4, mounting flange 2, described isolation diaphragm 4 is placed in the center of described mounting flange 2 measuring surface, the inboard cavity volume of the inner described isolation diaphragm 4 of described mounting flange 2 is equipped with working fluid 3, for pressure transmission; The pipe adapter of the center pit that the measuring surface of described TPMS automobile tire pressure monitoring sensor 1 is equipped with and described mounting flange 2 is threaded connection fastening.
During use, measured medium pressure acts directly on isolation diaphragm 4, diaphragm produces distortion upwards, by working fluid 3, pressure medium is passed to the chip of TPMS automobile tire pressure monitoring sensor 1, make the compression face of described chip produces displacement, by microcontroller and transmitter module, displacement is converted to data and to go forward side by side row relax, finally transmit to the receptacle (see figure 2) in digital display controller.
