Unveiling a New Era of Wireless Measurement and Control! The ABB 266DSH Wireless HART Differential Pressure Transmitter

With the deepening development of the Industrial Internet of Things (IIoT), unprecedented demands have been placed on the deployment flexibility and data accessibility of field instruments. In response, ABB officially introduces its innovative ABB 266DSH Differential Pressure Transmitter. This revolutionary product deeply integrates the WirelessHART communication protocol, designed to provide a wiring-free, highly reliable, and cost-effective intelligent measurement solution for process control applications across various industries such as oil and gas, chemicals, and power generation. It excels particularly in handling monitoring points in hazardous environments and hard-to-reach locations.

1. True Wireless Intelligent Measurement:
   The core value of this product lies in its integrated WirelessHART protocol. It completely breaks the dependence of traditional 4-20mA signals on cables, allowing users to easily add measurement points to existing plant networks and achieve wireless monitoring of key process variables such as pressure, level, and flow. This enables personnel to monitor remotely and effectively isolate risks when operating in hazardous environments, significantly enhancing safety and operational efficiency.

2. Exceptional Long-Term Cost-Effectiveness:
   The ABB 266DSH Wireless Pressure Transmitter boasts a battery life of approximately 10 years at a 32-second update rate. This ultra-long endurance drastically reduces the maintenance costs and replacement frequency throughout the device's lifecycle, offering users a highly cost-effective and reliable long-term monitoring solution.

The ABB Differential Pressure Transmitter 266DSH not only offers wireless advantages but also ensures stable performance in harsh industrial environments with its robust technical parameters:

• High Measurement Accuracy and Wide Range: Accuracy reaches ±0.06%, with a measuring range covering 0.05 to 16,000 kPa. This meets a wide spectrum of measurement needs from low to high pressure, providing the data foundation for precise process control.

• Strong Environmental Adaptability: Constructed from Stainless Steel (SS) with a high IP68 protection rating, it is completely dust-tight and can withstand prolonged submersion in water. Its operating temperature reaches 90°C. This ensures stable performance when measuring various media including gas, liquid, and vapor.

• Flexible Interface and Signal Options: Features a standard M20*1.5 interface and supports a dual signal output mode of 4-20mA + HART. This provides users with flexible access choices combining both wired and wireless options, ensuring strong compatibility.

Based on these features, this ABB 266DSH Transmitter demonstrates significant advantages in the following industrial scenarios:

• Oil and Gas: Remote monitoring of wellhead pressure, pipeline differential pressure, and tank level.

• Chemical and Pharmaceutical: Reactor pressure control, filter differential pressure monitoring, and pressure monitoring in clean areas.

• Power and Energy: Boiler air supply systems, steam flow measurement, and water circulation system monitoring.

• Utilities: Pressure monitoring in urban heating networks and level measurement in water treatment plants.

The launch of the ABB 266DSH Wireless HART Differential Pressure Transmitter marks a solid step forward for industrial field instruments towards wireless and intelligent operation. It is not just an innovation of a single product but a transformation of traditional factory monitoring network architectures.

By eliminating complex wiring projects, reducing installation and maintenance costs, and enabling seamless remote access to critical data, this product perfectly aligns with the core demands of modern industry for improving efficiency, ensuring safety, and lowering the total cost of ownership. It is rapidly becoming a strategic choice for users across industries in their journey towards digital transformation and building the smart factories of the future.
