ABBe 264 Differential Pressure Transmitter - Technical Description
The ABBe 264 Differential Pressure (DP) Transmitter is a high-performance industrial instrument designed for precise measurement of differential pressure, flow, and level in demanding process environments. As part of ABBe's legacy measurement portfolio, this transmitter combines robust mechanical engineering with advanced digital communication capabilities, making it suitable for applications in oil and gas, chemical processing, power generation, and water treatment. Its reliability, accuracy, and adaptability to harsh conditions have established it as a trusted solution for critical process control tasks.
Core Technical Parameters
The ABBe 264 operates over a wide differential pressure range, spanning 0.1 kPa (0.015 psi) to 40 MPa (5,800 psi), accommodating both low-pressure gas systems and high-pressure liquid or steam applications. It achieves an industry-leading accuracy of ±0.075% of span, inclusive of linearity and hysteresis, ensuring precise data acquisition even in dynamic industrial processes. The device is loop-powered, requiring a 12-45 V DC supply, and delivers a 4-20 mA analog signal integrated with HART® 7 digital communication for bidirectional data exchange. For fully digital control systems, optional PROFIBUS PA or Foundation Fieldbus protocols are available, complying with IEC 61158-2 standards.
Static pressure tolerance extends up to 100 bar (1,450 psi), while the process temperature range covers -40°C to +120°C (-40°F to +248°F), with ambient operational limits of -50°C to +85°C (-58°F to +185°F). A rapid response time of <100 milliseconds (adjustable via damping settings) ensures real-time monitoring of fast-changing processes, such as compressor surge control or boiler feedwater regulation.
Mechanical Design and Material Construction
The ABBe 264 features a 316L stainless steel housing with IP66/IP68 ingress protection, safeguarding internal components against dust, water jets, and temporary submersion up to 3 meters. Its robust design is tailored for corrosive or high-vibration environments, such as offshore platforms or chemical plants. The sensing element utilizes a 316L stainless steel diaphragm as standard, with optional Hastelloy C-276 or tantalum diaphragms for aggressive media like hydrogen sulfide , hydrochloric acid (HCl), or high-temperature steam.
Process connections comply with global standards, including ¼" NPT, G½", and ANSI/DIN flanges, enabling seamless integration into diverse piping configurations. Sealing materials range from EPDM/FKM for general use to Kalrez® for extreme chemical resistance, ensuring compatibility with hydrocarbons, acids, and alkaline solutions. The dual-compartment electronics housing isolates sensitive components from mechanical stress and thermal fluctuations, while explosion-proof variants meet ATEX/IECEx Ex d IIC T6 Gb certifications for deployment in Zone 1/21 hazardous areas.
Advanced Functional Capabilities
Multivariable Measurement: Beyond differential pressure, the transmitter calculates flow rates (via built-in square root extraction) and monitors static pressure and process temperature, delivering four critical variables in a single device.
HART® 7 Integration: Enables remote configuration, diagnostics, and calibration using handheld communicators or asset management software like ABBe's FieldCare™. Real-time alerts for diaphragm coating, plugging, or electrical faults enhance predictive maintenance.
Long-Term Stability: With a drift rate of ±0.1% of URL per decade, the ABBe 264 minimizes recalibration intervals, reducing lifecycle costs and downtime.
SIL 2 Certification: Complies with IEC 61508/61511 for safety instrumented systems, achieving a Safe Failure Fraction (SFF) of 90% and Hardware Fault Tolerance (HFT=1).
