1、 Mining type compensating micro pressure gauge | YJB-2500 | Application of compensating differential pressure gauge
Compensating micro pressure gauges are used to measure non corrosive gases, positive pressure, negative pressure, and differential pressure within a pressure range of less than 2500Pa, and can also be used to calibrate other pressure gauges.
2、 Mining type compensating micro pressure gauge | YJB-2500 | Brief description of compensating differential pressure gauge structure
The compensating micro pressure gauge consists of a fine-tuning part, a leveling observation part, a reflector part, and a housing part
1.Fine adjustment section - consisting of a fine adjustment disc engraved with 200 equal parts, fixed on a long screw. When the long screw moves, the water receiver moves up or down. A gauge block is installed on the static pressure nozzle of the water receiver, which moves between the gauge plate and the character plate to indicate the displacement height of the water receiver.
2Leveling observation section - equipped with a water level head inside the observation cylinder to observe the changes in the liquid level inside the observation cylinder after being pressurized by the dynamic pressure tube.
3The reflector part is fixed on the mirror shell by a reflector, which reflects the contact between the water level head inside the observation cylinder and the liquid surface, so that the tip of the water level head is in contact with the shadow tip of its reflection, indicating the adjustment of the micro pressure gauge reading "base point"
4Shell part - supported by the shell and crossbeam, the long screw is equipped with a leveling bubble and adjusting screw on the shell to adjust the verticality of the screw and dynamic pressure tube of the micro pressure gauge.
