DYHGRG-12 Thermal Measurement Training Device
Release time：2024-06-13 17:30viewed：times
Experimental purpose:
Demonstrate the composition and types of measuring instruments, understand the basic concepts of measurement errors, general measurement methods, representation methods and error processing methods, as well as technical indicators for evaluating the quality of measuring instruments. The focus is on the basic composition and functions of thermal instruments. The sensing element is directly connected to the measured object, senses the changes in the measured parameters, and converts the measured parameter signals into corresponding signal outputs that are convenient for measurement and display. The middleware transmits the signal output by the sensing element directly to the display element or amplifies and converts it to a signal that adapts to the display element. The display element reflects the value changes of the measured parameters to the observer.
M*n configuration:
According to the measured parameters: pressure, temperature, flow measurement instruments. It consists of sensing elements, middleware and display elements. The measurement system consists of four basic links: sensor , converter or transmitter, transmission channel, digital display device, st*nless steel stand and control panel.
Technical parameters:
1. Input power: single-phase AC220V±10% 50Hz, power 1.5KW.
2. 304 st*nless steel heating water tank, volume 40L, heating power 3.0KW; heat exchanger area is 3.0m2, 40W cooling fan.
3. Hot water pump parameters: flow: 20L/min, head: 12m, power: 120W.
4. Flow measurement, DN15 turbine flowmeter: measurement range 0.2-6.0m3/h; pressure measurement: pressure sensor: measurement range 0-0.6MPa.
5. The temperature is measured by a high-precision temperature sensor, and the universal signal input inspection instrument is combined with a high-precision digital display to display all experimental measurement parameters such as temperature, pressure, and flow.
6. Dimensions: 1600×500×1500mm, the appearance is a st*nless steel movable bracket with double brake wheels.
7. Virtual simulation software for electrical installation of building buildings and intelligent buildings Based on unity3d design, users can choose different sizes of interactive interfaces according to computer configuration, and can choose six levels of image quality.
