Utility model content
Goal of the invention: the purpose of this utility model is to solve the deficiencies in the prior art, provides a kind of exhaust temperature emission sensor performance testing device.
Technical scheme: a kind of exhaust temperature emission sensor of the utility model performance testing device, comprises Low-temperature Ice groove, high temperature oil groove, programmable logic controller (PLC) and display touch-screen; Be provided with High Accuracy Thermocouple Temperature in described Low-temperature Ice groove, in high temperature oil groove, be provided with High Accuracy Thermocouple Temperature and well heater, meanwhile, in Low-temperature Ice groove and high temperature oil groove, be all placed with measured piece; Described measured piece and two High Accuracy Thermocouple Temperatures are connected to programmable logic controller (PLC) respectively by temperature transmitter, be interconnected between described programmable logic controller (PLC) and display touch-screen, programmable logic controller (PLC) gathers and judges the temperature data in Low-temperature Ice groove and high temperature oil groove, then display touch-screen is shown in, in the enterprising line parameter editor of display touch-screen, input and output and control operation.
Use dirigibility and range of application for increasing, described Low-temperature Ice groove also can replace with low temperature tank.
For ensureing the even and constant of temperature, in described Low-temperature Ice groove and high temperature oil groove, be provided with self-poking arrangement.
Further, described programmable logic controller (PLC) is also connected with pilot lamp and hummer.
Further, also solid-state relay is provided with between described programmable logic controller (PLC) and well heater
Beneficial effect: the utility model programmable logic controller (PLC) (i.e. PLC) gathers the resistance value of the multiple temperature spot of exhaust temperature emission sensor and water (oil) groove temperature value, export to touch-screen display, and whether qualifiedly judge, meanwhile PLC is also used for constant high temperature oil sump temperature.Compared with prior art, the utility model has the following advantages:
(1) the utility model adopts PLC to control, and is easy to programme and subsequent adaptation to individual parameter, simultaneously because PLC is electrical equipment control height integrated equipment, simplifies circuit and electric elements, has saved cost.
(2) the utility model adopts industry control man-machine interface, practicality easy and simple to handle.
(3) all with self-poking arrangement in two calibration cells in the utility model, thus the even of temperature is ensured.
In sum, the exhaust temperature emission sensor that the invention provides a kind of accurately practicality quick, with low cost, easy and simple to handle is performance test bed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below technical solutions of the utility model are described in detail, but protection domain of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of exhaust temperature emission sensor performance testing device in the present invention, comprises Low-temperature Ice groove (or low temperature tank), high temperature oil groove, programmable logic controller (PLC) and display touch-screen; Be provided with High Accuracy Thermocouple Temperature in described Low-temperature Ice groove (or low temperature tank), in high temperature oil groove, be provided with High Accuracy Thermocouple Temperature and well heater, meanwhile, in Low-temperature Ice groove (or low temperature tank) and high temperature oil groove, be all placed with measured piece; Described measured piece and two High Accuracy Thermocouple Temperatures are connected to programmable logic controller (PLC) respectively by temperature transmitter, be interconnected between described programmable logic controller (PLC) and display touch-screen, programmable logic controller (PLC) gathers and judges the temperature data in (or low temperature tank) and high temperature oil groove, then display touch-screen is shown in, in the enterprising line parameter editor of display touch-screen, input and output and control operation.
Self-poking arrangement is provided with in above-mentioned Low-temperature Ice groove (or low temperature tank) and high temperature oil groove.Programmable logic controller (PLC) is also connected with pilot lamp and hummer, and and is also provided with solid-state relay between well heater.
Specific works principle of the present utility model is:
The utility model adopts constant temperature ice (water) groove and thermostatic oil bath, with PLC, the resistance value of the multiple temperature spot of temperature sensor and water (oil) groove temperature value are gathered, export to touch-screen display, and whether qualifiedly judge, meanwhile PLC is also used for constant high temperature oil sump temperature.
In Low-temperature Ice (water) groove side, PLC judges the temperature of ice groove by High Accuracy Thermocouple Temperature, gathers the resistance value of dut temperature sensor simultaneously, itself and theoretical value is compared, thus judge whether qualified; Afterwards PLC will gather data, and judged result export to display touch-screen, pilot lamp and hummer.
Survey at high temperature oil groove, principle is identical, adds oil groove heating arrangement (i.e. well heater), and carries out thermostatic control.
Proving installation is provided with the button such as " starting to test ", " stopping test ", " suddenly stopping ", display touch-screen has soft key, parameter editor can be carried out, the operations such as parameters input output and control.
Proving installation in the utility model finally can realize following functions:
1, fixed temperature point (passing through measured piece), the resistance of test exhaust temperature emission sensor, it is qualified to judge whether;
2, along with rising or the reduction of temperature, describe temperature resistance curve (passing through PLC), the whole temperature changing process of product is tested and demarcated;
3, can detect the resistance value of multiple temperature spot simultaneously and judge.
