Yokogawa ADMAGAE Magnetic Flowmeter

The Yokogawa ADMAG AE, also cataloged as the ADMAG AE Magnetic Flowmeter, operates as a dedicated hardware component for volumetric fluid velocity evaluation, localized Faraday-law induction tracking, and real-time liquid throughput digitization within process industrial networks. Configured as an inline electromagnetic induction array, the solid-state instrument conditions microvolt-tier electromotive potentials directly into standardized industrial signaling parameters.

Hardware Specifications

Process Control & DCS Instrumentation Rails

• 4-20 mA HART Loop Protocol and Channel-to-Channel Isolation The flowmeter converter uses an isolated 4-20 mA DC loop circuit to relay volumetric flow vectors directly to master distributed control system networks. Internal galvanic isolation barriers separate the low-voltage sensor coil excitation circuits from the primary signaling tracks. This topology suppresses common-mode voltage fluctuations, preventing electrical loop noise from creeping between the transmitter rails and adjacent 4-20 mA HART loop networks sharing the same routing banks.
• Dual Frequency Excitation and Signal Conversion Pathways The internal analog-to-digital core utilizes Dual Frequency Excitation to modulate the magnetic field potential across the flow tube. By combining low-frequency stabilization elements with high-frequency sampling sweeps, the conversion engine filters out electrochemical slurry noise natively at the hardware tier. This signal conversion pathway resolves flow-induced electromotive force variables within millisecond processing indices without demanding extra computation cycles from the host DCS.

Frequently Asked Questions

Q: How does the dual-compartment housing design improve long-term electrical reliability in humid plant fields?

A: The dual-compartment casting separates the field terminal strip from the sensitive amplifier boards via an internal physical partition wall. This structural barrier ensures that during routine maintenance or when running field wiring cables, airborne moisture and corrosive ambient gases cannot enter the clean electronic housing segment containing the microprocessor logic chips.

Q: What are the specific application advantages of the 99.9% ultra-high purity alumina ceramic lining?

A: The ultra-high purity alumina ceramic lining provides exceptional structural rigidity, high chemical inertness, and resistance against abrasive slurry wear. This wetted-surface boundary maintains shape integrity under high-velocity process flows, preventing lining vacuum collapse or tracking degradation that could alter the internal diameter calibration values.
