Axial with Edge Explosion-proofElectric Contacts Pressure Gauge

  • Pipe segment ultrasonic flow meter
    INQUIRY
Ⅰ. Application
This instrument can use in the site that is with explosive mixture, used for measuring the copper and copper alloy, common carbon steel and other non-corrosive of crystals, non-solidification of medium’s pressure (negative pressure). Can use together with the relevant explosion-proof property electric element via contact device.
 Note: measuring the corrosive medium, crystallization and coagulation medium, should use acid proof, antiseptic or diaphragm explosion-proof pressure gauge, measure tiny pressure (10 Kpa ~ 60 Kpa), should use diaphragm capsule explosion-proof pressure gauge, measure of vibration occasions use magnetic assist type explosion-proof pressure gauge or use digital explosion-proof pressure gauge.

Ⅲ. Structure and Working Principle
1. This pressure gauge shell uses flame-proof structure, when the shell internal explosive mixtures affected by sparks or electric arc, when the explosion occurred, do not cause external explosive mixture explode, so as to achieve the goal of explosion-proof.
 
2, instrument is consist by bourdon pressure gauge and an electric connect device.
Instrument working principle: when the medium get into the spring tube, make its produce displacement, enlarge through the drive mechanism, pointer will be indicate the measured pressure value in the dial. At the same time the pointer drive electric contact device’s movable contact, when the pressure reaches index value, movable contact contacts set pointer’s contact terminal, and processing circuit.
