2. Applicable scope of embedded wires for building electronic thermometers
This instrument is suitable for on-site construction temperature measurement of various types of construction projects. When used with a temperature measurement probe, it can measure the temperature of materials and clinker, such as: Gases, liquids, fluids, mixtures and granular materials; Combined with the embedded temperature measurement line, it can measure the internal temperature of concrete and large-volume concrete constructed in winter.
3. Instrument composition and functions
The host can be connected with temperature measurement probes or temperature measurement wires to form a temperature measurement system, which can be flexibly configured according to site needs and the number of temperature measurement points.
1, host
The host is a portable instrument, equipped with a power switch, a lighting switch, a socket and an LCD display. It can digitally display the measured temperature value and has a lighting function for temperature measurement readings at night. In order to prevent dust, moisture and bumps, a thin film with good sealing performance is used. Touch switch and strap-type instrument cover can also be opened and the bracket behind the main unit can be placed on the desktop for use.
2, Building electronic thermometer embedded wire Temperature measuring probe
The temperature measuring probe is made of a plug, wire, handle and a metal tube with an outer diameter of φ6mm
3. Temperature measuring line
Pre-embedded temperature measuring wires are made of plugs, wires and temperature sensors. They are suitable for measuring the internal temperature of concrete. Each temperature measuring wire can measure a little temperature. Temperature measuring points can be arranged arbitrarily during construction. In order to facilitate layered temperature measurement, each temperature measuring wire can be The plugs of each temperature measuring wire are labeled with corresponding length specifications.

five, Building electronic thermometer embedded wire How to use
1． Use the host computer and temperature probe to measure material temperature
Insert the plug of the temperature measurement probe into the host socket, press the power switch, and insert the metal rod of the temperature measurement probe into the object to be measured. The insertion depth shall not be less than 1/ 2. Read the temperature data on the host computer for about two minutes. When measuring the temperature of the mixture, in order to avoid excessive impact between the temperature measuring probe and hard objects in the mixture and affecting the service life, you can first use a metal stick to Reserve a hole in the hole, and then insert the temperature probe into the hole to measure the temperature. The temperature probe should be wiped clean after each use.
2. Use the host computer and temperature measuring line to measure the temperature of large-volume concrete
After the construction temperature measurement plan is determined, temperature measurement lines with appropriate length and specifications should be selected based on the number and depth of temperature measurement points, such as: The actual temperature measurement point is 0.2m ~ 0.3m deep, and a temperature measurement line with a specification of 0.5m can be used; The actual temperature measurement point is 2.5m ~ 2.8m deep, and a temperature measurement line with a specification of 3m can be used, and so on. When pre-embedded, steel bars and other rods can be used as supports. The temperature measurement line should be tied to the distance between the longitudinal temperature measurement points. On the support, heat insulation treatment should be done between the temperature sensor and the support. When pouring concrete, the support with the temperature measurement wire tied to it is implanted into the concrete. The temperature sensor is at the temperature measurement point, and the plug is left outside the concrete and used. 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 and insert the temperature measurement wire plug into the socket of the host. The screen of the host will be displayed. The temperature of the corresponding temperature measurement point can be displayed.
3. Building electronic thermometer embedded wire Use the host machine and temperature measuring line to measure the temperature of concrete during winter construction
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 and insert the temperature measuring wire plug into the socket of the host. The temperature of the corresponding temperature measuring point will be displayed on the display of the host. After each stage of temperature measurement, store the temperature measuring wire for later use. Reuse it next time. You can also bury the temperature measurement wire in concrete for one-time use. For details, see the instructions." 2”.
4. Use of lighting function for night temperature readings
When using it at night or in a dark environment, press the lighting switch of the main unit and the LCD screen will emit a light green background light to make the readings clear and eye-catching.
6. Battery replacement
When the battery symbol appears in the upper left corner of the host display or cannot be turned on normally, it is generally due to insufficient battery voltage and the battery needs to be replaced. The method is as follows: Push down the battery compartment cover behind the host, open the battery compartment, take out the old battery, fasten the new battery, and then return the battery compartment cover to its original position.
seven, Building electronic thermometer embedded wire Things to note
1． When the host is not connected to the temperature measuring probe or temperature measuring line, it will be displayed on the display."- 1" is the preparation status.
2. Do not use excessive force during operation, and hold the plug firmly when inserting or unplugging the plug into the host socket.
3. The plug and host socket should be kept away from moisture and kept clean. If water accidentally enters and gets damp, please wipe it and dry it before use to avoid inaccurate temperature measurement results.
4. The instrument should be shut down promptly after use, and the battery should be removed when not in use for a long period of time to avoid damage to the instrument.
5. Do not open the back cover of the main unit by yourself. If maintenance or calibration is required, please return it to the manufacturer or agency.
