1 Wide Turndown Ratio, 100ms Fast Response, LCD Display, A HART Smart Pressure Transmitter Built for Demanding Applications like Petrochemicals and Power

In industrial environments pursuing process stability and efficient operations, the accurate, reliable, and fast measurement of pressure for various media such as oil, water, and gas is the cornerstone for optimizing control, ensuring safety, and improving energy efficiency. Xi'an Xinyi Instrument Technology Co., Ltd. formally introduces and promotes the star product from Honeywell—the SmartLine ST700 Series Pressure Transmitter. As a core member of the Honeywell SmartLine Intelligent Product Line, this integrated Gauge/Absolute/Sealed Pressure transmitter, with its ultra-high ±0.065% base accuracy, industry-leading 100:1 wide turndown ratio, and 100ms fast response capability, combined with HART protocol smart communication, provides a comprehensive solution from precise measurement to efficient management for industries such as petrochemicals, power generation, pharmaceuticals, and food.

1. Exceptional Measurement Performance and Stability
   The core advantage of the Honeywell ST700 Pressure Transmitter lies in its industry-benchmark accuracy and long-term stability. Its base accuracy is as high as ±0.065%, with a long-term stability index of ±0.02%. This means it can provide extremely reliable pressure data over operating cycles lasting several years, significantly reducing the need for maintenance and recalibration. The wide span limits (50 to 10000 psi) combined with the 100:1 ultra-wide turndown ratio allow a single device to cover a broad spectrum of application scenarios, greatly simplifying user selection and inventory management.

2. Advanced SmartLine Platform and Digital Integration
   As a member of the SmartLine Intelligent Instrument Family, the ST700 is not just a measurement unit but an intelligent process node. It natively integrates the HART communication protocol, allowing users to easily perform remote configuration, diagnostics, and data access via a hand-held communicator or asset management system. The high-definition LCD digital display supports on-site local reading and parameter setting. Its fast 100ms response time can sensitively capture pressure transient changes, providing critical data support for dynamic process control.

The robust capabilities of the Honeywell ST700 Pressure Transmitter are backed by the following series of excellent parameters:

• Top-Tier Accuracy and Wide-Range Capability: Base accuracy ±0.065%, long-term stability ±0.02%, turndown ratio 100:1, response time 100ms. Offers three pressure type choices: Gauge, Absolute, and Sealed Pressure, flexibly adapting to different working conditions.

• Rugged Reliability and Environmental Adaptability: Wetted parts are made of stainless steel for strong corrosion resistance, suitable for measuring various industrial media such as oil, water, and gas. Wide power supply range of 10.8 - 42.4 VDC, compatible with various global industrial power standards, facilitating easy installation and commissioning.

• Intelligent Interaction and Standard Output: Standard 4-20mA analog output and HART digital signal for seamless integration into existing DCS or PLC systems. The LCD display makes on-site operation clear at a glance.

Thanks to its high performance, high reliability, and intelligent features, this Smart Pressure Transmitter is indispensable in the following core industrial fields:

• Petrochemicals and Natural Gas: Pipeline pressure in refining units, reactor pressure, natural gas compressor discharge pressure monitoring.

• Power and Energy Industry: Boiler drum pressure, steam turbine monitoring, power plant water treatment system pressure measurement.
