CX-PG-SYEC-100/150B
(Double Lower Limited Contact Structure) Explosion-proof Electric Contact
Pressure Gauge
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. It has a variety of function to measured medium pressure, such as automatic control, alarm, signal remote etc.
Note: Measured pressure below the set pointer, two set pointer contact are normally closed status; Measured pressure above the set pointer, two set pointer contact are normally open status; Suitable for when system pressure rises up, it can have double limit alarm function, can also be used to automatically control in set pressure range.
Measure 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.
Ⅱ. Basic Parameter
1. Technical data
2. dimension 100mm dimension 150mm
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 consists 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.
3, insert line of rubber sealing ring inside diameter 10 mm, Shao Ershi hardness 45 to 55 with cable diameter 9.8 mm, 500 VBX type four core lastex (4XI)
