Classic Reliability, Intuitive Precision: The New Instrument YB-150 Series 4-Inch Mechanical Pressure Gauge
In an era where digital technology is sweeping through the industrial sector, the mechanical analog pressure gauge still plays an irreplaceable role in countless on-site monitoring tasks, thanks to its unique advantages of requiring no power supply, rugged durability, and intuitive readability. Xi'an Xinyi Instrument Technology Co., Ltd., deeply understanding the timeless value of classic instrumentation, proudly introduces the YB-150 Series 4-inch (100 mm) Mechanical Pressure Gauge. Specifically designed for routine pressure monitoring within the range of 0 to 600 PSI, this product utilizes the proven Bourdon tube (phosphor bronze) sensing principle. Combined with a clearly legible 4-inch dial and a standard 1/4-inch NPT connection, it offers reliable accuracy of ±1.5% FS, wide temperature adaptability from -40°C to 60°C, and a stainless steel case, making it the ideal auxiliary choice for HVAC systems, air compressors, water pumps, and various general industrial equipment.
Core Product Highlights: Classic, Durable, At a Glance
1. All-Mechanical Structure, Ultimate Reliability Without PowerThe core value of the YB-150 lies in its all-mechanical design. It relies entirely on the internal phosphor bronze Bourdon tube, which elastically deforms under pressure, driving a pointer via a precision linkage to indicate pressure on the dial. The entire process requires no external power, fundamentally eliminating electrical faults, electromagnetic interference, and explosion-proof hazards. This makes it the most stable and reliable monitoring choice for high-safety applications like the chemical and petroleum industries, as well as areas without on-site power supply.
2. 4-Inch Large Dial, Clearly Readable from a DistanceThe product features a clear 4-inch (100 mm) diameter dial with distinct graduations and a prominent pointer. Even in low-light conditions or when installed at a distance, operators can quickly and accurately read the current pressure value. This intuitive analog display allows observers to instantly perceive pressure changes and trends through the pointer's position and swing – a unique advantage not offered by digital displays.
3. Rugged Construction and Standard Connection, Easy to IntegrateThe YB-150 is equipped with a stainless steel case, effectively resisting oil, moisture, and general corrosion. Its 1/4-inch NPT standard tapered pipe thread connection is an industry standard in North America and internationally, offering strong compatibility and easy installation on various pipes, valves, and equipment. The bottom-mounted design is simple and sturdy, suitable for most panel or direct-mounting scenarios.

A Legacy of Precision, Unwavering Reliability: The Rosemount 3051CD Differential Pressure Transmitter (HART Protocol / Explosion-Proof)
In the process industry, the Rosemount 3051 series has long been a symbol of unparalleled reliability, accuracy, and technological heritage in the field of pressure measurement. Nowadays, Xi'an Xinyi Instrument Technology Co., Ltd. brings this classic original Rosemount 3051CD differential pressure transmitter (HART protocol/explosion-proof type) to domestic users. It embodies decades of on-site experience and technological essence, providing a globally validated "gold standard" solution for key flow, liquid level, density, and pressure measurements in industries such as petroleum, chemical, power, and metallurgy with its exceptional stability, rich self diagnostic capabilities, and powerful HART communication capabilities.
1. Globally Recognized Classic Platform andPerformance
The 3051CD inherits theperformance genes of the Rosemount family. Its sensor is ingeniously designed to measure both differential pressure and static pressure simultaneously, transmitted remotely via HART communication protocol. The device features extremely fast response (power-up time < 15 seconds), excellent static pressure effect (±(0.05% URL + 0.075% Span)/10MPa), and minimal power supply effect (±0.001%/10V), ensuring it consistently delivers and reliable process variables amidst complex process fluctuations.
2. Powerful Intelligence and Self-Diagnostic Capabilities
This is more than just a transmitter; it's an intelligent field instrument node. Using the HART protocol, engineers can remotely configure, commission, and monitor it from the control room or with a handheld communicator. Its built-in self-diagnostic functions continuously monitor the transmitter's health and can provide status outputs for pressure high/low alarms, significantly enhancing the plant's predictive maintenance capabilities and overall safety.

High Temperature Precision, Right Before Your Eyes: The New Instrument YW-140G Intelligent Digital Display High-Temperature Pressure Transmitter
In industrial processes such as petroleum refining, high-temperature steam, and food sterilization, media temperatures often soar above 200°C. The challenge for pressure measurement lies not only in the temperature resistance of the sensing core but also in enabling operators to read data intuitively and accurately on-site. Traditional remote-mount instruments often lack local displays, causing inconvenience for inspections and debugging. Xi'an Xinyi Instrument Technology Co., Ltd. precisely addresses this need with the launch of the YW-140G Stainless Steel High-Temperature Pressure Transmitter. This innovative product integrates high-temperature measurement capability with on-site digital display, utilizing an imported high-temperature resistant chip and an efficient heat dissipation structure design to reliably measure media temperatures up to 300°C. Equipped with a 5-digit LCD display, it allows engineers to clearly read real-time pressure right next to boilers or sterilization tanks. With its all-stainless steel construction, IP65 protection rating, and exceptional long-term stability (≤0.2% FS/year), the YW-140G provides an intelligent solution that combines accuracy and convenience for demanding high-temperature applications in industries like petroleum, chemicals, boilers, and food & pharmaceuticals.
Core Product Highlights: High-Temperature Resistant, With Display, High Stability
Integrated Heat Dissipation Design, Confidently Facing 300°C ChallengesThe YW-140G is specifically engineered for high-temperature environments. Its core features a 316L stainless steel isolation diaphragm and an imported high-temperature resistant sensor chip, with a specially designed efficient heat dissipation structure between the pressure port and the electronics housing. This design effectively isolates heat conduction, ensuring internal electronic components operate within a safe temperature range, enabling the transmitter to directly measure process media up to 300°C. It perfectly handles pressure monitoring in scenarios involving boiler steam, hot oil, and high-temperature reactors.
Integrated digital display, easy to read on-site readings at a glanceUnlike ordinary non display pressure transmitters, YW-140G integrates a clear 5-digit LCD display screen at the top. This allows on-site operators to directly read the current pressure value next to the equipment without the need for additional tools or handheld terminals, greatly facilitating daily inspections, on-site debugging, and troubleshooting. The screen displays clearly, adapts to outdoor lighting environments, and enhances the safety and convenience of operation.
Durable and sturdy design, suitable for various harsh environmentsThe transmitter body adopts a fully stainless steel structure, combined with a sturdy aluminum alloy junction box, with an overall protection level of IP65, which can effectively resist dust, moisture, and rain, suitable for outdoor or humid industrial site installation. The product undergoes strict testing and aging screening from components, semi-finished products to finished products, ensuring long-term stability of better than 0.2% FS/year, and can withstand mechanical vibrations of 20g (20-5000Hz). It can also work stably near vibration sources such as compressors and pumps.
