Description
Technical field
The utility model relates to automobile water tank radiator Performance Detection field, particularly, relates to a kind of multichannel pressure and temp monitoring and recording system.
Background technology
Automobile water tank radiator all can carry out alternating pressure test verify its endurance quality in design, fabrication phase.Generally, water tank is imported and exported and is connected to one and closed be full of medium and maintain the circulation system of certain flow and temperature, and the system force value that also repeats to apply some cycles and amplitude on request acts on water tank and carries out permanance checking.
Usually, the radiator of water tank of several different sizes can be arranged on testing equipment and test simultaneously by alternating pressure test, setting pressure sensor and temperature sensor on testing equipment, measure the pressure and temperature parameter of each test specimen, owing to installing one group of pressure and temperature sensor, unified measurement is carried out to each test specimen, after making off-test, pressure, the temperature parameter of each sample of the same battery of tests of record are all identical.But, because length of pipe is different, the parameter differences to some extent such as the pressure on each sample, temperature.But existing testing equipment is in order to meet the installation question of different size sample, cannot by the position of sensor as far as possible near exemplar import, so the temperature and pressure of each exemplar inflow point accurately cannot be measured, can not count separately the pressure of each sample, temperature parameter.Therefore, the test of existing automobile water tank radiator alternating pressure exist measuring accuracy low, count inaccurate technical matters.
Utility model content
For defect of the prior art, the purpose of this utility model is to provide a kind of multichannel pressure and temp monitoring and recording system.
According to an aspect of the present utility model, a kind of multichannel pressure and temp monitoring and recording system is provided, comprise: multiple pressure transducer, multiple temperature sensor and recording instrument without paper, each pressure transducer, temperature sensor are arranged on automobile water tank radiator, the probe of pressure transducer, the probe of temperature sensor are all connected with the water inlet of radiator of water tank and the water inlet pipe of radiator of water tank, and recording instrument without paper is connected with each pressure transducer and temperature sensor respectively.
Preferably, also comprise multiple isolating transmitter, the input end of each isolating transmitter is connected to corresponding pressure transducer and temperature sensor respectively, and output terminal is connected to recording instrument without paper.
Preferably, temperature sensor adopts thermopair.
Pressure transducer, temperature sensor are arranged on the water inlet of radiator of water tank by the utility model, by the temperature and pressure parameter at pressure transducer and temperature sensor independent acquisition test sample inlet place, make up connecting line exemplar difference to the impact of test findings.By isolating transmitter, temperature and pressure signal is converted to the 4-20mA current signal mated with acquisition system, by recording instrument without paper each road current signal is converted to corresponding data and carries out stored record.Compared with prior art, the utility model has following beneficial effect: multichannel pressure and temp monitoring and recording system of the present utility model is by independently pressure transducer, temperature sensor are arranged on all separately the water inlet of radiator of water tank separately, and by pressure and temperature data that material registering instrument real time record collects, can the pressure and temperature parameter of each sample of real time record separately, have measuring accuracy high, count advantage accurately.
