The mining double needle seismic pressure gauge series is a specialized pressure gauge for fully mechanized mining supports, used to measure the pressure and peak value of fully mechanized mining equipment under high pulse pressure and harsh operating conditions in coal mines. This instrument has the characteristics of small size, high accuracy, shock resistance, impact resistance, and memory value. The diameter of the meter head is Φ 40、 Φ 50、 Φ 60、 Φ The 100 connection methods are KJ10, DN10, plug-in rod connection, and jack connection. The measurement range is 60MPa, 80MPa, and 100MPa, which can also be customized according to needs.
Main technical indicators:
1. Models Y-40, Y-50, Y-60;
2. Accuracy: 2.5 level;
3. Measurement range: 0-60MPa, 0-80MPa, 0-100MPa;
4. Dial outer diameter: φ 40mm、 φ 50mm、 φ 60mm;
5. Applicable environment: temperature -10 ℃~+50 ℃, humidity not exceeding 98% relative;
6. Shockproof: When subjected to vibrations of 5-60Hz and 5g acceleration, there is no significant shaking of the pointer.
Instructions for use:
1. Before use, first reset the auxiliary needle (red needle) to zero by hand, and then perform a pressure test. The main needle (black needle) displays the current pressure, and the auxiliary needle displays the high pressure during the testing process.
2. After use, the needle should be returned to zero.
3. Do not open the pressure gauge after it malfunctions to avoid damage.
4. The calibration regulation for this pressure gauge is JJG52-87.
5. When two or more pressure gauges are used for a device, a boxed dual needle seismic resistant pressure gauge for mining can be selected.
