The Tianjin the Huayin Construction Instrument Technology Co., Ltd. "mass concrete thermometer newly developed high-quality mass concrete thermometer manufacturers | large mass concrete thermometer Profile in building construction, mass concrete is under the common features Concrete: structure thick, a large amount of concrete, complex engineering, construction and technical requirements. Cement hydration heat temperature deformation structure, it is necessary to take appropriate technical measures, so as to reduce the cracking caused by temperature deformation. As we all know, the general problems of mass concrete, not the mechanics of structural problems, but the cracks due to temperature changes, leading to the impermeability of concrete, crack resistance, anti-erosion performance degradation, affecting the durability of the whole structure. In practical work, mass concrete temperature changes can be divided into: warming period, cooling and stability of three stages, a large number of experimental data show that the concrete in 1-3 days after pouring temperature rise inside the concrete the highest temperature occurs mostly within 3-5 days after pouring, five days after the concrete temperature is in the decline stage, therefore, within 1-5 days after the pouring of the concrete should be closely observing the changes of the concrete temperature, the temperature once every 2-4 hours, 5 days after every 6-8 hours temperature measure atmospheric temperature at the same time, until the measures are not taken in surface temperature, the table air temperature difference can be controlled in the specification requirements. In addition, when measured at different depths within the concrete and surface temperatures, all measuring points should be number, and shall promptly temperature records sent to the site responsible for the sign read, in order to take timely and appropriate measures to control concrete temperature changes. Operating points. Temperature measurement points and depth of selection specifications suitable temperature line wire is reinforced as the support for embedded, the first temperature line tied to the reinforced line temperature sensing element of the temperature should be in the position of the measurement points, and shall not be in direct contact with reinforced. 2. Before pouring concrete, reinforced tie temperature line implanted in the concrete plug to stay on the outside, and cover with a plastic bag to avoid moisture and keep clean, easy to operate, leaving the outside temperature line length should be greater than 20cm and press the upper, middle and lower order lashing. 3. Wireless temperature: stay outside temperature line plug into the wireless collector outlet, the wireless thermometer host can be displayed simultaneously the temperature of the measuring point. The wired temperature: thermometer host switch is pressed, turn each measuring point plug inserted into the host outlet, the host screen to display the corresponding measuring point temperature. 4. Carefully recorded, analyzed temperature data, and report the results to the requester in a timely manner. Technical parameters: 1, temperature range: -50 ° C to -120 ° C, the device working environment temperature: -20 ° C -60 ° C 3. Measurement Points: 24 channels (expandable), the sensor is connected Maximum length: 50 meters Power supply: 220V/AC terminal, the radio host of the standby power DC5V 6, means of communication: local USB communication primitives end wireless LAN communication 7, collecting between
