1、 YJ-1 kiln type wood moisture detector

The kiln type wood moisture meter is a continuous wood moisture content measuring instrument that can continuously track and detect the wood inside the kiln. It has the characteristics of fast detection speed, high accuracy, multi-point measurement, intuitive reading, and easy operation. The YJ-1 kiln type wood moisture meter uses Harris large-scale integrated circuit technology from the United States to ensure high sensitivity and accuracy in measuring wood moisture. This instrument uses LED digital display to directly display the current moisture content of the wood in the drying kiln, and sets up tree species correction based on the resistance characteristics of various woods. It also sets up temperature correction based on the temperature inside the kiln during the drying process, thereby reducing the measurement error caused by this. YJ-1 kiln type wood moisture analyzer is an ideal instrument for detecting the moisture content of wood in drying kilns in the wood industry.

3、 YJ-1 kiln type wood moisture detector _ Instructions for using kiln wood moisture detector

1. Power on preheating

Before using the instrument, it should be turned on and preheated for 15 minutes.

2. Temperature correction

When measuring at room temperature, the temperature correction knob is generally placed between 20 ℃ and 30 ℃; When measuring wood during or after drying, adjustments can be made based on the ambient temperature in which the wood is located. When measuring continuously, attention should be paid to the temperature and hysteresis of the wood during the heating and cooling process.

3. Tree species correction

Adjust the tree species correction knob to the corresponding tree species gear in the attached table to adapt to different tree species measurements.

4. Sensor connection (nail connection)

The connecting wire adopts a single core shielded wire, and one end of the core wire and the metal shielding mesh are connected to two sensors respectively. The two sensors are nailed to the tested inspection board at a distance of 30mm, with a depth of~for rectangular wood and~for cylindrical wood diameter; The other end is connected to the terminal of the instrument measuring point, with the core wire connected to the red terminal and the metal shielding mesh connected to the corresponding black terminal.

5. Measurement of wood without listed tree species correction file

First, measure several specimens with balanced moisture content as much as possible at the four positions of the tree species switch. Then, the moisture content of the specimen is determined using the dry balance weight method. The position where the tree species conversion switch deviates from the dry balance weight method can be used for future selection of the tree species for measurement. If the above adjustment test method is not used, the transfer switch can generally be placed in the third gear for measurement.

4、 YJ-1 kiln type wood moisture analyzer _ Precautions for kiln wood moisture analyzer

1. The distance between the connecting wires depends on the distance between the instrument and each detection point, and should generally be less than 15 meters.

2. If the temperature of the connecting wire is greater than 70 ℃, high-temperature resistant wires should be used.

3. The instrument must be grounded.

Weiyang Instrument Knowledge: Kiln type wood moisture detector is a specialized instrument for measuring the moisture content of wood in drying kilns. Industries that heavily use wood, such as flooring, furniture, and wooden doors, require the purchase of large quantities of raw wood (undried wood) as raw materials. Raw materials cannot be directly used for production and need to be dried in a drying kiln before they can be used for the production of flooring, furniture, and wooden doors. During the drying process of wood in a kiln, due to the high temperature, we cannot enter to measure the moisture content of the wood. The YJ-1 kiln type wood moisture meter effectively solves this problem. Operators can directly observe the instruments placed outside the drying kiln to determine the degree of dryness of the wood inside the kiln.
