YKY series mining memory pressure gauges

◆ Model: YKY60

◆ Application: Mining memory pressure gauges is specially designed for underground hydraulic support in coal mines. It has the characteristics of small size, high precision and strong vibration resistance, and is suitable for measuring the pressure of liquids, gases or vapors without explosion hazard, no crystallization, no solidification, and no corrosive effect on copper and copper alloys under the condition of strong mechanical vibration and violent pulsation of the medium.

◆ There is a specially designed needle retention device inside the instrument. It is possible to memorize the peak pressure pulse of the system under test during use.

◆ Before the instrument is used, the memory needle will be adjusted to the zero position by the counterclockwise direction with the button in the center of the watch window, when the pressure of the system under test rises, the red memory needle will follow the movement of the pressure indicator needle and move, when the pressure of the system under test appears instantaneous peak pulse, the memory needle will stay at the highest point of the peak, which is used to warn and inform the inspection personnel, so that the operator can make early treatment according to the situation to ensure the safe operation of pipelines and equipment. After the operator reads and records, the memory pointer is dialed back to zero in the counterclockwise direction and put into operation again.

With an accuracy level of 2.5, the gauge delivers dependable readings suitable for environments where ruggedness and durability are more important than high-precision measurement.
Maintains stable performance despite vibrations, shocks, and fluctuating loads common in mining operations
IP65 Ingress Protection – Built for Dusty and Wet Mine Environments
The IP65 enclosure rating offers excellent protection against:
Dust intrusion, ensuring components remain uncontaminated even in coal or ore dust environments
Water spray, allowing reliable operation in areas with dripping water, high humidity, or cleaning operations
