Explosion Proof Pressure Gauge
Model: YX-ZT
The YX-ZT explosion-proof pressure gauge combines a 100 mm axial front flange, selectable scale, stainless pressure system, and adjustable contacts in one configurable sourcing package. Its reinforced case, double-layer safety glass, rear pressure-relief cover, and compatible wetted parts support hazardous process monitoring. It suits installations that need local indication and limit switching together.
Dial and Mounting100 mm, axial front flange
Pressure SystemSUS304 or SUS316
Primary ApplicationHazardous process indication and alarm
Supply PositionStandard and configured orders
MOQ1 sample; 10 production pieces
CustomizationRange, thread, material, dial, and contacts
Standard configurations can ship in 1–2 working days; routine configured gauges require 3–5 working days after specification and payment approval.
Which YX-ZT Specification Produces a Comparable Quote?
A comparable YX-ZT quotation depends on one locked combination of scale, dial format, mounting direction, process connection, wetted material, and contact duty.
The 100 mm axial front-flange format suits panel mounting, while selectable pressure scales, M20×1.5 or custom threads, and upper/lower slow-action contacts define the orderable configuration.
Pressure scale and 100 mm dial format define the readable working range.
Axial front-flange mounting fixes the panel geometry and rear clearance.
M20×1.5 or an ordered alternative fixes the process interface.
SUS304 or SUS316 wetted parts are selected for the process medium.
Upper and lower slow-action contacts define alarm or interlock duty.
One locked configuration keeps price and lead-time comparisons valid.
Which Safety Elements Define a Hazardous-Area YX-ZT Installation?
Hazardous-area suitability comes from the complete enclosure and process configuration, not from the pressure range alone.
A stainless case, double-layer safety glass, rear pressure-relief cover, compatible wetted parts, vertical installation, and the project-specific hazardous-area approval must be evaluated as one safety package.
Enclosure and Relief Direction
The reinforced stainless case and double-layer safety glass protect the movement, while the rear relief cover requires clear space away from personnel and sealed panel obstructions.
Process Compatibility
The Bourdon tube, socket, thread, and seal must remain compatible with the measured gas or liquid; viscous, crystallizing, or strongly corrosive media require a different isolation arrangement.
Electrical and Area Approval
The contact circuit, cable entry, grounding, hazardous-area classification, and project approval must match the complete ordered gauge rather than a family name or pressure range alone.
When Does YX-ZT Limit Switching Fit the Control Task?
Mechanical indication, limit switching, digital display, and remote transmission solve different control tasks even when all instruments measure pressure.
YX-ZT combines local pointer indication with adjustable limit contacts; a local-only gauge omits switching, while a digital gauge or transmitter adds electronic display, recording, or continuous remote output.

How Hangzhou Dongya Builds the Explosion-Proof Pressure Gauge
The manufacturer controls incoming parts, pressure-system assembly, calibration, full inspection, labeling, and export packing.
Hangzhou Dongya Instrument Co., Ltd.
Established in 2002, the company manufactures pressure gauges at its Fuyang District plant in Hangzhou. YX-ZT orders move through incoming inspection, Bourdon-tube welding, movement assembly, dial and pointer fitting, pressure adjustment, enclosure sealing, calibration, full inspection, labeling, and protective packing.
Pressure-gauge manufacturing and export are within the registered business scope.
Leakage pretests use 1.25× full scale before final assembly.
Final checks cover zero, rising and falling indication, hysteresis, light tapping, and sealing.
Routine configured orders support range, thread, material, dial, logo, and contact requirements.
