Price for supplying empty box pressure gauges

Mining empty box pressure gauge/DYM3-2 mine air pressure gauge/pointer type empty box pressure gaugeworking principle：
Shanghai Longtuo Instrument Company is a professional manufacturer of air pressure gauges and mercury pressure gauges. Our mature and professional production process is integrated into every air pressure gauge, providing * atmospheric pressure measuring instruments for numerous domestic and foreign enterprise users. The DYM3 air box pressure gauge supplied by Shanghai Longtuo Instrument is divided into three models: DYM3 flat prototype air box pressure gauge; DYM3-1 plateau type air box pressure gauge; DYM3-2 underground empty box pressure gauge; The measurement principle of the DYM3 series empty box pressure gauge is to use a vacuum meteorological membrane box as the sensing element. With the change of atmospheric pressure, axial displacement is generated. Through the connecting rod and gear transmission mechanism, the pointer is driven to rotate on the dial, and its reading is the atmospheric pressure at that time. The Longtuo air box pressure gauge has the advantages of easy portability, accurate measurement, wide pressure measurement range, easy use and maintenance, and no mercury pollution. It is widely used in fields such as meteorology, military, aviation, navigation, agriculture, measurement, geology, industrial and mining enterprises, and scientific research, and has become a conventional instrument for measuring atmospheric pressure.
Usage:
1、Please place the Longtuo empty box pressure gauge horizontally when using.
2、Please lightly tap the instrument casing or surface glass 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 value, with the reading accurate to one decimal place.
4、Read the temperature reading on the Longtuo pressure gauge to one decimal place.
5. DYM3-2 mine empty box pressure gauge is professionally supplied by Shanghai Longtuo. Welcome to purchase:.
6、The calculation of air pressure value: The air pressure reading on the instrument can only be used after correction.
Precautions for Longtuo empty box pressure gauge:
(1) The Longtuo air box must be placed horizontally during pneumatic operation to prevent reading errors caused by tilting
(2) Users should not remove the air pressure from the hollow box inside the plastic shell to avoid unnecessary damage.
(3) Due to the fact that the supplementary correction value of Longtuo air box pressure may change over time, the supplementary correction value must not exceed the six-month service life, and must be re calibrated if exceeded.
(4) Users are not allowed to adjust the adjustment screw without authorization to avoid increasing the error of the instrument.
(5) When there is a malfunction in the air pressure of the Longtuo empty box, please send it to Shanghai Longtuo Instrument Company for professional repair. Do not disassemble it by yourself.
