JDC-2 Henan concrete thermometer wire

1. Measure the material temperature with the host and temperature probe
Insert the plug of the temperature probe into the host socket, press the power switch, and insert the metal rod of the temperature probe into the measured object, with a depth of not less than 1/2 of its length. After about two minutes, read the temperature data on the host. When measuring the temperature of the mixture, in order to avoid excessive impact between the temperature probe and the hard objects in the mixture, which may affect the service life, a metal rod can be used to reserve a hole in the mixture first, and then the temperature probe can be inserted into the hole for temperature measurement. After each use, the temperature probe should be wiped clean.

2. Measure the temperature of large volume concrete using a host and temperature measuring cable
After the construction temperature measurement plan is determined, appropriate length and specifications of temperature measurement lines should be selected based on the number and depth of temperature measurement points. For example, if the actual temperature measurement point depth is 0.2m to 0.3m, a temperature measurement line with a specification of 0.5m can be selected; The actual temperature measurement point depth is 2.5m-2.8m, and a temperature measurement line with a specification of 3m can be selected, and so on. When embedding, steel bars and other rods can be used as supports, and the temperature measurement line should be tied to the support according to the distance between the longitudinal temperature measurement points. The temperature sensor and the support should be insulated. When pouring concrete, insert the support with the temperature measuring wire tied into the concrete, place the temperature sensor at the temperature measuring point, leave the plug outside the concrete and cover it with a plastic bag to avoid moisture and keep it clean. For ease of operation, the length of the wire left outside should be greater than 20cm. When measuring temperature, press the power switch of the host, insert the temperature measurement cable plug into the host socket, and the temperature of the corresponding temperature measurement point will be displayed on the host display screen.

3. Measure the temperature of winter construction concrete using a host and temperature measurement line
When pouring concrete, reserve temperature measurement holes according to the winter construction temperature measurement plan, place a temperature measurement wire in each hole, leave the plug of the temperature measurement wire outside the hole and cover it with a plastic bag to avoid moisture and keep it clean. When measuring temperature, press the power switch of the host, insert the temperature measurement cable plug into the host socket, and the temperature of the corresponding temperature measurement point will be displayed on the host display screen. After each stage of temperature measurement is completed, store the temperature measurement line for future use. The temperature measuring wire can also be buried in concrete for one-time use. The specific method is described in "2" of the usage instructions.
