Yhy60 intrinsic safety digital pressure gauge for coal mine

 
Yhy60 intrinsic safety digital pressure gauge single meter for Coal Mine 1、 Introduction , Yhy60 intrinsic safety digital pressure gauge for coal mine is mainly used for pressure detection of fully mechanized mining support, single hydraulic prop and other hydraulic equipment
It is composed of resistance pressure sensor, electronic circuit controlled by microprocessor and dry battery
The instrument adopts integrated design and has the characteristics of waterproof, explosion-proof, impact resistance, high sensitivity and long service life
It is an ideal substitute for the traditional pointer pressure gauge& Nbsp 2、 Yhy60 coal mine intrinsic safety digital pressure gauge single gauge technical indicators 1

Install , Fully mechanized mining support monitoring: hang or fix the pressure gauge under the support (select the appropriate position according to different support forms), and the sensor passes through Ф 10mm high-pressure oil pipe is connected with the pressure tap of the column Single hydraulic prop monitoring: single channel mining digital pressure gauge is equipped with fixed transfer valve, which can be connected with the three-purpose valve of single prop 2
Operation , Illuminate the indicator window with a miner's lamp once or press the start key
Both methods can make the display window display the pressure (unit: MPa), and automatically turn off the power after 5 seconds& Nbsp 4、 Precautions for use: , 1
The protective conditions shall be taken into account when installing the pressure gauge, and it shall avoid extrusion and severe impact& Nbsp 2
When the display brightness is dimmed or the display is unstable, first consider whether the internal battery has reached the service life, and replace the battery (limited to the safety battery pack provided by the manufacturer) on the well 5、 Common faults and Analysis When the display of digital pressure gauge is unstable and the display is very dark, the battery voltage is insufficient, and the battery should be replaced
