Tianjin the Huayin Construction Engineering Instrument Technology Co., Ltd. "mass concrete thermometer Thermometer manufacturers of high-quality mass concrete | Introduction to Mass Concrete thermometer in the construction, mass concrete subordinates common feature newly developed The structure of concrete: a thick, large amount of concrete conditions complicated engineering, construction technical requirements. Cement hydration heat temperature deformation structure, it is necessary to take appropriate technical measures, as much as possible to reduce the temperature deformation caused cracking. As we all know, the general problem of mass concrete, not structural problems in the mechanics, but the cracks due to temperature changes, leading to the decline in performance of the impermeability of concrete, crack resistance, anti-erosion, affect the durability of the whole structure. Mass concrete temperature changes in the actual work, the process can be divided into: the three stages of the warming period, the cooling phase and stationary phase, a large number of experimental data shows that 1-3 days after the concrete pouring temperature is on the upswing, the highest concrete inside temperature occurs mostly within 3-5 days after the pouring of the concrete temperature is in the decline stage after five days, 1-5 days after concrete pouring concrete temperature changes should be closely observed temperature measurement once every 2-4 hours, 5 days every 6-8 hours temperature measure atmospheric temperature at the same time, until the inner temperature difference measures are not taken, the the table temperature difference can be controlled in the specification of requirements range. In addition, different depths inside the concrete and the surface temperature measurement, all measuring points should number and shall promptly temperature records sent to the site technical person in charge of check reading, in order to take appropriate and timely measures to control the concrete temperature changes. Operating points. In accordance with the temperature measurement points and the depth of the chosen specifications suitable temperature line wire is reinforced as the supports embedded first wire is tied reinforced on, the temperature sensing element temperature line should be in the position of the measurement points, and shall not be in direct contact with the reinforcement. 2. Before pouring concrete, rebar tie wire is implanted in the concrete plug is left out, and cover with a plastic bag to avoid moisture and keep clean, easy to operate, should be greater than the length of stay in the outside temperature line 20cm, the press, and the middle and lower order respectively banding. 3. Wireless Temperature Measurement: stay in the outside temperature measurement cord into the wireless collector outlet temperature of the measuring point the wireless thermometer host can be displayed simultaneously. Wired temperature: Press the thermometer host switch, turn each measuring point plug inserted into the host receptacle on the host screen to display the temperature of the measuring point. 4. Careful notes and analysis of measurement data, and report the findings to the requester in a timely manner. Technical parameters: 1, temperature range: -50 ℃ -120 ℃ equipment working environment temperature: -20 ℃ -60 ℃ 3. Temperature measurement points: 24 channels (scalable) 4, the maximum length of the sensor is connected: 50 meters Power supply: Terminal 220V/AC, standby power wireless host DC5V 6, means of communication: the local USB communication primitives terminal wireless LAN communication, collected between
