Core Inheriting Classics, Intelligence Leading the Future: The New Instrument XYM-3051 Monocrystalline Silicon Intelligent Pressure Transmitter

In the process industry, the pursuit of high precision, high stability, and high reliability in pressure measurement is an eternal theme. Xi'an Xinyi Instrument Technology Co., Ltd., leveraging its profound technical expertise, proudly introduces the XYM-3051 Series Monocrystalline Silicon Intelligent Pressure Transmitter. This product employs advanced monocrystalline silicon pressure sensor technology and temperature compensation processes. Combined with a unique center overload protection diaphragm design and built-in surge protection circuit, it accurately measures critical parameters such as gauge pressure, absolute pressure, differential pressure (functionality), flow, level, and density. With its accuracy up to 0.1% FS, wide media temperature range of -40°C to 110°C, Exd II CT6 Gb explosion-proof rating, and all-316L stainless steel construction, the XYM-3051 is the ideal choice for industries like petroleum, chemicals, power generation, and metallurgy to replace traditional instruments and enhance automation levels.

Core Product Highlights: Monocrystalline Silicon Core, Dual Protection, Intelligent and Reliable

1. High-Performance Monocrystalline Silicon Sensor, the Foundation of Precision and Stability
The core of the XYM-3051 utilizes a highly stable monocrystalline silicon pressure sensor. Compared to traditional diffused silicon or ceramic sensors, monocrystalline silicon material offers excellent elastic characteristics and long-term stability with extremely low hysteresis and drift. Coupled with comprehensive temperature compensation technology, it effectively eliminates the impact of ambient temperature changes on measurement, ensuring the transmitter delivers accurate readings up to 0.1% FS even under complex conditions, with long-term stability better than ±0.1% FS/year.

2. Patented Dual Overload Protection Design, Confidently Handling Pressure Shocks
Addressing common pressure peaks and pulsations in industrial settings, the XYM-3051 features an innovative center overload protection diaphragm structure. This structure effectively isolates and absorbs impact energy when one or both sides承受instantaneous high pressure, protecting the core sensor from damage. Combined with a static pressure limit of up to 25 MPa and強大的single-ended overload resistance, this greatly enhances the transmitter's survivability and long-term reliability in complex hydraulic and pneumatic systems.

3. Powerful Intelligence and User-Friendly Interaction
The transmitter supports standard 4-20mA output with HART protocol, enabling seamless integration with control systems and remote parameter setting and diagnostics. Equipped with an intelligent LCD display, it supports local zero and span adjustment and information viewing, making on-site operation intuitive and convenient. The entire series features a explosion-proof die-cast aluminum housing with IP65 protection and has obtained Exd II CT6 Gb explosion-proof certification, allowing safe use in hazardous areas like oil and gas fields and chemical plants.

4. Rich Material Options and Wide Media Compatibility
The standard version uses 316L stainless steel for wetted parts. Depending on media corrosiveness, higher-performance diaphragm materials like Hastelloy C or Tantalum can be selected. Paired with Viton O-rings and silicone oil fill fluid, it confidently handles measurement needs for water, oil, gas, and various mildly corrosive chemical fluids.
