Emerson EZ1000 – Non-Invasive Current Measurement System | EZ Series Platform
Engineering Background
Accurate current measurement is foundational to energy management, motor protection, and process control in industrial environments. Traditional inline current sensing requires circuit interruption and introduces installation risk. The Emerson EZ1000 eliminates this constraint with a clamp-on, non-invasive architecture that delivers precision measurement without breaking the circuit.
Product Positioning
The EZ1000 is engineered for procurement engineers and system integrators who require a reliable, calibrated current transducer for continuous monitoring in demanding industrial settings. It is a direct-fit solution for energy metering panels, motor control centers (MCCs), and distributed I/O architectures where downtime for sensor installation is not acceptable.

System Architecture & Signal Flow
The EZ1000 operates as a passive clamp-on current transformer (CT) coupled with an integrated signal conditioning module. The conductor under measurement passes through the clamp jaw, inducing a proportional secondary current. The onboard electronics linearize and scale this signal to a 4–20 mA output, which is wired directly to the analog input channel of the host controller. No primary circuit modification is required. The loop-powered design minimizes auxiliary wiring and simplifies panel layout.
Typical signal chain: Energized conductor → EZ1000 clamp jaw (CT core) → Signal conditioner → 4–20 mA output → PLC/DCS AI card → SCADA/HMI display

Technical FAQ
Q: Can the EZ1000 measure DC current?
A: Yes. The EZ1000 is rated for both AC and DC current measurement. Verify polarity orientation for DC applications per the installation guide.
Q: What is the maximum conductor diameter the clamp jaw accepts?
A: Refer to the Emerson EZ1000 dimensional drawing for exact jaw opening. Contact us if you need to measure large-diameter busbars — we can advise on compatible accessories.
Q: Is the 4–20 mA output loop-powered or does it require separate auxiliary power?
A: The EZ1000 is designed for loop-powered operation (2-wire, 4–20 mA). Confirm with the datasheet for your specific revision.
Q: Can I use this with a Siemens S7 or Allen-Bradley ControlLogix PLC?
A: Yes. The 4–20 mA output is a universal industrial standard compatible with any PLC analog input module rated for current input. No special configuration is required beyond scaling the AI channel to 0–1000 A.
Q: Do you offer calibration certificates?
A: Calibration certificates are available for new-in-box units. Contact [email protected] to request documentation prior to order.
Q: What is the minimum order quantity (MOQ)?
A: MOQ is 1 unit. Volume discounts apply for orders of 5+ units. Contact us for a tiered pricing schedule.
