1. Product Overview
The ABBe 264 Series represents a premium line of differential pressure (DP) transmitters engineered for extreme reliability in demanding industrial environments. As part of ABBe's 2600T series, these transmitters integrate advanced digital technologies with robust mechanical designs to deliver ±0.075% base accuracy - among the highest in the industry
Key applications include:
Flow measurement (venturi, orifice plates)
Liquid level monitoring in tanks/vessels
Filter/valve differential monitoring
HVAC system balancing
Process line pressure drops
Designed to operate under static pressures up to 3045 psi (21 MPa) and process temperatures ranging from -58°F to +250°F (-50°C to +121°C), they comply with PED Category IV standards for safety-critical applications .
3. Innovative Features
3.1 Advanced Sensing Technology
The capacitive silicon sensor employs laser-trimmed piezoresistive elements and ASIC-based signal conditioning. Its symmetrical design minimizes static pressure effects, maintaining accuracy even under 21 MPa (3045 psi) line pressures .
3.2 Digital Architecture Featuring a 32-bit DSP with 0.01% resolution, the transmitter supports:
Automatic temperature compensation (-40°F to +185°F)
Real-time diagnostics (sensor integrity, electronics health)
Dynamic flow compensation algorithms
3.3 Modular Design Philosophy
The patented "sensor+electronics" modularity allows:
Field replacement of communication modules (HART→PROFIBUS in <5 mins)
Isolation flange retrofitting without recalibration
LCD display add-on/removal without process shutdown
4. Communication & Configuration
4.1Configuration Methods
Local Interface: 5-digit LCD with 50-segment bargraph + tactile keys for zero/span adjustments
Handheld Terminals: DTMs compatible with ABBe FieldIT® or PACTware®
Software Platforms: Asset Vision Basic, Symphony Plus
