JIECHUANG
Engineered for precision, this low range diaphragm pressure gauge accurately captures subtle pressure variations in liquid, gas, and steam environments, providing reliable data for critical process control.
The specialized robust diaphragm acts as a physical barrier, effectively isolating corrosive, highly viscous, and easily crystallized media. This prevents internal mechanism blockage and safeguards the delicate internal gauge parts from premature wear.
Encased in an industrial-grade stainless steel housing with a smooth, polished finish, the interior is filled with high-purity glycerin or silicone oil. This dampening fluid neutralizes severe mechanical vibrations, ensuring a steady dial reading and a significantly extended operational lifespan.
Built to meet rigorous international standards including ISO 9001 and ASME guidelines, this instrument delivers authoritative compliance for seamless integration into large-scale engineering projects and strict facility approvals.
It serves as a vital measurement component across diverse sectors, delivering tailored solutions for fluid power systems, petrochemical refineries, municipal water treatment facilities, and sanitary food and pharmaceutical processing lines.
When the pressure (P) of the targeted measured medium exerts force upon the sensitive diaphragm, the metallic surface undergoes a calculated micro-deformation. This mechanical shift compresses the specialized sealing fluid housed within the instrument's closed pressure measurement system, generating a transmitted pressure of P-△P. Because the rigidity of the diaphragm is formulated to be exceptionally low, the pressure differential (△P) remains minimal and negligible. Consequently, the internal system pressure mirrors the actual medium pressure with remarkable fidelity. This direct-transfer mechanism guarantees that engineers receive immediate, uncompromised readings on the dial. The tactile responsiveness of the diaphragm ensures that even the most minute pressure fluctuations are captured instantly, providing operators with the precise data required to maintain optimal system safety, fluid stability, and overall operational efficiency.

Note: All technical parameters listed above can be fully customized to align with specific operational requirements. We provide comprehensive OEM and ODM manufacturing capabilities, allowing engineers to specify unique pressure ranges, specialized exotic alloy materials, and distinct connection threads. Beyond standard configurations, our value-added services include complete assembly integration and Vendor Managed Inventory (VMI) programs designed to streamline your supply chain. Whether your facility requires specialized dials with custom branding, specific wetted parts for highly aggressive chemicals, or bulk packaging solutions, our engineering team collaborates closely with your procurement department to deliver tailored instrumentation that precisely matches your complex field conditions.
For optimal accuracy and to prevent mechanical stress on the internal linkage, pressure gauges must be installed in a strictly horizontal or vertical orientation, depending on the specified connection type.
During the installation or routine disassembly process, operators must never apply manual rotational torque directly to the instrument housing. Always utilize properly sized, dedicated wrenches on the designated wrench flats to secure the connection, protecting the structural integrity of the casing.
The instrument is engineered to function reliably within a normal ambient operating temperature range of -40℃ to +70℃, provided the relative environmental humidity does not exceed 85%. Maintaining these conditions prevents internal condensation and ensures dial clarity.
To support your engineering and maintenance teams, we provide comprehensive technical documentation. Complete product datasheets, detailed installation and maintenance manuals, and precise 2D/3D CAD selection drawings are available for download, facilitating in-depth system evaluation and accurate design integration.

The superior corrosion resistance of our diaphragm pressure gauges is achieved through the strategic selection of premium materials for all wetted components, including the diaphragm, flange, and sealing gaskets. By matching the metallurgy to the specific chemical composition of the measured medium, we eliminate the risk of structural degradation. Available diaphragm materials include OCr17Ni12Mo2 (SUS316L) for general industrial use, Monel alloy (Cu3ONi70) for marine environments, Hastelloy (H276C) for aggressive acids, Tantalum (Ta), and fluoroplastic (F4) coatings. Complementing these are robust flange constructions utilizing SUS304, SUS316, or specialized PTFE-lined variants. This tailored approach ensures that the gauge withstands highly reactive substances, maintaining a pristine, unblemished surface over years of continuous exposure, thereby reducing maintenance frequency and enhancing overall system reliability.
To facilitate seamless procurement for large-scale industrial operations, we offer structured bulk order policies featuring transparent, tiered pricing discounts that significantly reduce overall acquisition costs. Our highly optimized production lines and extensive inventory of standard components allow us to maintain predictable, standardized lead times, ensuring that both routine restocks and massive custom orders are delivered right on schedule. Furthermore, every pressure gauge is backed by a comprehensive warranty policy and a straightforward Return Material Authorization (RMA) process. Should any operational anomalies occur, our dedicated technical support channels provide immediate troubleshooting and guidance. This robust after-sales framework is designed to completely eliminate procurement risks, giving buyers the absolute confidence that their investment is protected by responsive, expert service throughout the product's entire lifecycle.
