Anemometer Classification Application and Precautions for Use
Anemometer, an instrument for measuring air velocity, can be widely used in various fields, such as electric power, steel, petrochemical, energy saving and other industries. In daily life, many industries need to use anemometer, such as fan manufacturing industry, sea fishing industry, Exhaust, exhaust, heating systems, etc., all need to use anemometers to measure wind speed, wind temperature, and air volume to ensure normal operation.
Thermal anemometer--measurement of airflow in the pipeline
Industrial exhaust pipes and heating system pipes are mostly installed in higher places due to the high temperature of the exhausted air or excessive volume. For the measurement of such pipes, it is most suitable to use the probe anemometer for measurement. . DT-8880 thermal anemometer, with telescopic probe, is an expert in airflow measurement in narrow ducts and small spaces. This anemometer has a portable design, which can measure wind speed, wind temperature, and air volume, and is suitable for low wind speed measurement. Large backlit LCD display with high precision and reliable data. In addition, the anemometer can also input the cross-sectional area of the pipeline to calculate the air volume.
Vane anemometer--exhaust and exhaust measurement
Due to the high-speed area generated on the surface of the free vent, the rest of the area is a low-speed area, and a vortex is generated on the grid. In this case, at a certain distance (about 20cm) in front of the grid, it is most appropriate to use an impeller-type anemometer for measurement, because the larger-caliber impeller can average the unbalanced flow velocity and calculate its velocity in a larger range. average value. The vane-type anemometer DT-620 has a double-cast plastic shell, easy to use, and simple to operate, with data hold and maximum and minimum hold functions. In addition, the anemometer temperature sensor adopts NTC type high-precision thermistor, and the wind speed sensor adopts ultra-low friction bearing, which has high accuracy and high sensitivity.
Precautions for use of anemometer and thermal anemometer
1. It is forbidden to use the anemometer in a flammable gas environment.
2. It is forbidden to place the anemometer probe in flammable gas. Otherwise, fire or even explosion may result.
3. Do not disassemble or modify the anemometer. Otherwise, electric shock or fire may result.
4. Please use the anemometer correctly according to the requirements of the instruction manual. Improper use may cause electric shock, fire and sensor damage.
5. During use, if the anemometer emits abnormal smell, sound or smoke, or liquid flows into the anemometer, please shut down immediately and take out the battery. Otherwise, there will be danger of electric shock, fire and damage to the anemometer.
6. Do not expose the probe and anemometer body to the rain. Otherwise, there may be danger of electric shock, fire and personal injury.
7. Do not touch the sensor inside the probe.
8. When the anemometer is not in use for a long time, please take out the internal battery. Otherwise, the battery may leak and cause damage to the anemometer.
9. Do not place the anemometer in places with high temperature, high humidity, dusty and direct sunlight. Otherwise, it will cause damage to internal components or deterioration of the performance of the anemometer.
10. Do not wipe the anemometer with volatile liquid. Otherwise, the shell of the anemometer may be deformed and discolored. If the surface of the anemometer is stained, it can be wiped with a soft cloth and neutral detergent.
11. Do not drop or put heavy pressure on the anemometer. Otherwise, it will cause malfunction or damage of the anemometer.
12. Do not touch the sensor part of the probe when the anemometer is charged. Otherwise, it will affect the measurement result or cause damage to the internal circuit of the anemometer.
