The utility model relates to a multi-sensor parallel module for improving large-range pressure measuring accuracy, which comprises a pressure transmitter, a pressure transmitter inlet valve, a plurality of high pressure pipelines, a plurality of high pressure solenoid valves and a plurality of pressure sensors. The multi-sensor parallel module is characterized in that the pressure transmitter is in a closed circular tube shape; a pressure transmitting liquid inlet is arranged at one end of the pressure transmitter; a valve is arranged on an inlet pipe; the plurality of high pressure pipelines connected with the pressure transmitter are parallelly arranged on one side of the pressure transmitter; the pressure sensors with different measuring ranges are installed at the other ends of the high pressure pipelines; the high pressure solenoid valves are installed among the pressure sensors and the pressure transmitter; and the pressure sensors are connected with a computer. By adopting the principle that liquid can not be compressed and the sealed structure of the sensor, the multi-sensor parallel module realizes the measuring of the pressure in different pressure sections in identical pressure point through the pressure sensors with different measuring ranges, improves the measuring accuracy, controls and manages the opening and closing of the high pressure solenoid valves and the operation of the pressure sensors through the computer, and ensures that the pressure sensors with small measuring range are not damaged.
Description
One, technical field
The utility model relates to a kind of pressure test module, specifically a kind of multisensor module in parallel that improves the wide pressure measuring accuracy.
Two, background technology
At present, need test increasing with the point pressure scope in producing and testing, measuring accuracy also requires more and more higher, and the variation range of test pressure may be from several kPas up to MPas up to a hundred, if use a sensor metering, be difficult to guarantee the measuring accuracy of different pressures section.
Three, summary of the invention
The purpose of this utility model provides a kind of multisensor module in parallel that improves the wide pressure measuring accuracy, solves the problem that improves the wide pressure measuring accuracy.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of pressure difference transmitter, pressure difference transmitter admission valve, high pressure line, high-pressure solenoid valve and pressure transducer, it is characterized in that pressure difference transmitter is made as airtight tubular type, be provided with the import of pressure transmission liquid at pressure difference transmitter one end, on induction pipe, be provided with valve, at the parallel many high pressure lines that are connected with pressure difference transmitter that are provided with of pressure difference transmitter one side, the high pressure line other end is equipped with the pressure transducer of different ranges, between pressure transducer and the pressure difference transmitter high-pressure solenoid valve is installed, pressure transducer and computing machine link.
It is the closed structure of incompressible principle and pressure difference transmitter that the utility model utilizes liquid, realized measuring the pressure of different pressures section and having improved measuring accuracy with the pressure transducer of the different ranges of point pressure utilization, computerized control and manage the operation of high-pressure solenoid valve keying and pressure transducer, guaranteed that little range pressure sensor is not damaged.

Five, embodiment
For further disclosing the technical solution of the utility model, elaborate by example below in conjunction with Figure of description:
Adopt the Hydrostatic Transfer Device principle also to claim pascal's principle on the utility model structure, promptly in the closed container, be added in the inactive liquid pressure of any arbitrarily and can be delivered to each point in the liquid, and its force value is constant.The pressure transducer 5 of different ranges (according to the measuring accuracy of test specification and sensor self, and the measuring accuracy that requires decides needed sensor number and range) is connected with high pressure line 3 and high-pressure solenoid valve 4 and be connected on the pressure tap of pressure difference transmitter 1.Before the beginning pressure measurement, earlier solenoid valve is all opened.And in advance with pressure measurement flow process pipeline full of liquid (the mobile volume change that liquid can not take place of valve core of the electromagnetic valve), open pressure transmission liquid imported valve 2 and begin pressurization, all pressure transducers are gathered and monitored to computing machine simultaneously, when pressure during smaller or equal to the range of 0.85 times of minimum range pressure transducer, monitoring software is chosen the observed pressure value of the numerical value of minimum range sensor as this point; When pressure during greater than the range of 0.85 times of minimum range pressure transducer; computing machine sends steering order; close the respective electrical magnet valve; little range pressure sensor is protected; this moment, the force value of this point was chosen the higher leveled sensor values of range; by that analogy, thus realized that pressure transducer is to the continuous precise metering with the some wide pressure.
