GB/T 7305-2003 Standard Industrial Instruments with IP67 Protection Level and ±1%F.S Output Accuracy

Product Description:

Endress+Hauser transmitters serve as the central component of the company's complete measurement solutions. They are designed to work together with E+H's top-tier sensors (probes) to establish accurate measurement points.

Modular and Platform-Based Design: Endress+Hauser adopts a unified platform design approach, such as the Heartbeat Technology platform. This ensures consistency across different transmitter types (pressure, temperature, flow, level) in terms of operation, configuration, software, and diagnostics, thereby simplifying user training and maintenance.

Superior Hardware Quality:

Housing: Typically made from robust cast aluminum or stainless steel, with protection ratings up to IP66/IP67 or NEMA 4X, capable of withstanding challenging industrial environments (e.g., explosion-proof, corrosion-resistant, wide temperature range).

Display Unit: Equipped with a large backlit LCD screen, rotatable 320°, offering clear data, curves, and status indicators visible from any angle.

Comprehensive Product Line: Encompassing measurement of critical process parameters including:

• Pressure/Differential Pressure Transmitters: e.g., Cerabar, Deltabar series.
• Level Transmitters: e.g., Micropilot (radar), Prosonic (ultrasonic), Levelflex (guided wave radar).
• Flow Transmitters: e.g., Promag (electromagnetic flowmeter), Promass (Coriolis mass flowmeter).
• Temperature Transmitters: e.g., iTEMP, Memograph M recorder.
• Water Quality Analysis Transmitters: e.g., Liquiline for pH, conductivity, dissolved oxygen, etc.

Features:

E+H transmitters offer far more than simple signal conversion; they are intelligent field devices.

High-Precision Measurement and Signal Processing: Utilizing advanced digital signal processing technology, they ensure highly accurate and stable measurement results, even under challenging process conditions.

Heartbeat Technology: This is E+H's flagship feature. It enables transmitters to:

• Perform online verification: Check whether the measurement point still maintains its promised accuracy without interrupting the process.
• Self-Diagnosis: Continuously monitors instrument and process conditions to detect potential issues early (e.g., fouling, pipe blockages, equipment failures).
• Predictive Maintenance: Provides maintenance timing windows, enabling users to shift from “unplanned downtime” to “planned maintenance,” significantly reducing costs.

Extensive Communication Protocols: Supports all major industrial communication protocols for seamless integration with control systems:

• Traditional Analog Signals: 4...20 mA HART.
• Digital fieldbuses: PROFIBUS DP, PROFINET, Foundation Fieldbus, MODBUS, etc.

Advanced diagnostics and safety features:

• Device health monitoring: Provides equipment lifecycle information.
• SIL certification compliant: Many transmitters are certified to SIL2/SIL3 safety integrity levels for use in safety instrumented systems (SIS).
• Event Logger: Records all critical operational and process events for troubleshooting.

User-Friendly Operation:

• Unified Operating Concept: Simple, intuitive setup via field buttons, infrared handheld communicator, or computer software (FieldCare).
• Plug-and-Play: Pre-configured sensors and transmitters enable rapid pairing, reducing commissioning time.
