Standard Room Temperature And Humidity Solutions
一.Introduction OF Standard Care Room
Standard Curing Room it is specially used for the standard maintenance of constant temperature and humidity of concrete test blocks and cement test blocks. The standard curing room conforms to the latest national standards. It has a wide range of uses and great promotion value in highway transportation, railways, bridges, civil buildings, water conservancy, hydropower, and scientific research units. Concrete curing room temperature and humidity intelligent controller is a curing equipment specially used for concrete laboratory. Above %RH。
二.Temperature and humidity detection principle
The humidity of the standard curing room must be kept above 95% and the temperature is 20℃±2℃. This kind of environment puts forward higher requirements for the monitoring of temperature and humidity, and most temperature and humidity sensors cannot work for a long time in such a high humidity environment. Our company designs temperature and humidity sensors separately. The humidity sensor uses capacitive humidity sensor as relative humidity monitoring, which can quickly dehumidify under long-term saturation, improving reliability and long-term stability. The patented solid polymer structure can be used for Linear voltage or frequency output loop, fast response time, temperature sensing uses a gold metal shell to package a thermistor, reaching IP68 waterproof level. In principle, this eliminates the problem that the sensor cannot work in a high-humidity environment。
三.Unattended standard maintenance room intelligent maintenance system
The national standard for the maintenance of the standard curing room is 20 ± 2 ℃, and the relative humidity is 95%. Usually, personnel need to check whether the room temperature and humidity are normal. Our company has made an automatic monitoring system for the greenhouse temperature monitoring of the standard room. Its block diagram is as follows:
四.The Composition Of The Maintenance System Of The Intelligent Standard Maintenance Room
The maintenance system of the intelligent standard curing room is composed of temperature and humidity sensor, DTU, and LED display screen. The following is the description of the whole system products:
