DAIICHI KEIKI GRK-A pressure gauge with anti-vibration Glycerin

Producer: DAIICHI KEIKI

Category: Gas concentration measuring device

DAIICHI KEIKI GRK pressure gauge with anti-vibration Glycerin GRK-A, GRK-B, GRK-D series
G-AU R3/8-75x100KPA, G-AU-R3/8-75X20MPA, G-AU-R3/8-75X1MPA,G-AU-R3/8-100X0.1MPA…
· Glycerin solution is added to provide appropriate vibration and pulsation. The reduced vibration has significantly improved the durability.
When the pulse pressure is high, it is generally not usable for a short time, but the durability is significantly improved when using this device. The comparison test results between the general type and this tester are as follows. Working pressure gauge: 100φ x 10 MPa Reference pressure 5 MPa Fluctuation ±0.5 MPa Frequency 1200/min Amplitude ±0.7 mm. General type: Needle increases 5° in about 70 hours. Glycerin-coated type: Needle increases 5° in 2200 hours. With a tolerance ratio of more than 30 times, the deviation of the needle during operation is approximately 1/6. In addition, because it has the same mounting hole as the general product, it can be interchanged even when using the general anti-vibration type. Glycerin solution is equivalent to kerosene type 4 and type 3 according to the Fire Prevention and Fighting Law, so the risk of fire and explosion is very low and because it is harmless, it can be used in the food industry.
· This superior vibration-proof type is suitable for pressure measurement under extreme vibration conditions.

Industrial Pressure Gauges

with Glycerin

Model: GRK-A Series

[Features]
· Glycerin solution is added for appropriate vibration and pulsation.
· A reduction in pulsation has drastically improved durability.

When the pulsating pressure is high, it often becomes unusable in a short period of time, but the durability is greatly improved by using this device. The results of the comparison test between the conventional type and this tester are as follows.
Working Pressure Gauge: 100φ x 10 MPa Reference Pressure 5 MPa
Pulsation ±0.5 MPa Frequency 1200/min Amplitude ±0.7 mm
General type: Needle goes up 5° in about 70 hours.
Glycerin Encapsulated Type: Needle Up 5° in 2200 Hours
With an endurance ratio of more than 30 times, the deflection of the pointer during operation is approximately 1/6. In addition, since it has the same mounting hole as the general product, it is interchangeable even when the conventional anti-vibration type is used. Glycerin solution is equivalent to class 4 and class 3 petroleum in the Fire Defense Law, so there is little risk of fire, and since it is harmless, it can be used for food industry.

[Applications]
· This super vibration-proof type is appropriate for pressure measurements under extreme pulsation.
