The DYM3 type empty box pressure gauge, also known as a bellows type atmospheric pressure gauge, is an atmospheric pressure measuring instrument that uses a vacuum bellows as the sensing element, also known as a bellows type pressure gauge. Empty box pressure gauges are widely used in fields such as meteorology, military, aviation, navigation, agriculture, measurement, geology, industrial and mining enterprises, and scientific research due to their advantages of easy portability, accurate measurement, wide pressure measurement range, easy use and maintenance, and no mercury pollution. They have become a common instrument for measuring atmospheric pressure.

1. Atmospheric pressure measurement range: 800-1064hPa

2. Small division value of pressure dial: 1 hPa

3. Temperature measurement range: -10 to+42 ℃

4. Temperature gauge small division value: 1 ℃

5. Measurement error of atmospheric pressure: The measurement error of atmospheric pressure after temperature, indication, and supplementary correction shall not exceed 2.0 hPa

6. Instrument weight: 1.5Kg

7. Instrument size: Ø 136 × 83mm

Working principle of DYM3 flat prototype empty box pressure gauge: The working principle of the empty box pressure gauge is to use an empty box group that moves axially with the change of atmospheric pressure as the sensing element. It drives the pointer through a pull rod and transmission mechanism to indicate the atmospheric pressure value at that time.

Usage of DYM3 flat prototype empty box pressure gauge:

1. Please place the empty box pressure gauge horizontally when using.

2. Please lightly tap the outer shell or surface glass of the empty box pressure gauge with your fingers to eliminate friction in the transmission mechanism.

3. When observing, the pointer overlaps with the mirror pointer, and the value pointed by the pointer is the air pressure indication value, with the reading accurate to one decimal place.

4. Read the temperature reading on the empty box pressure gauge to one decimal place.
