Product Details
The Emerson EZ1900-040, also cataloged as the EZ1900 Extension Cable, operates as a dedicated hardware component for probe signal extension between field-mounted proximity sensors and signal converters within Emerson AMS and EPRO machinery monitoring systems. It transmits high-frequency displacement signals across a 4.0 meter length while maintaining matched impedance for 8 mm eddy current probes.

4-20 mA HART Loop Protocol and Channel Isolation
The EZ1900-040 extension cable utilizes precision shielded copper conductors and FEP insulation to maintain continuous electrical shielding between the eddy current probe tip and the converter interface. This shielding preserves signal integrity over extended physical runs by preventing capacitive cross-talk and ambient electromagnetic interference from distorting high-frequency raw AC/DC signal paths before conversion into 4-20 mA HART loop protocol outputs at the monitoring transmitter.
Frequently Asked Questions
Q: How does cable length affect calibration in an eddy current probe system?
A: The EZ1900-040 cable is precisely length-matched (4.0 meters) and impedance-matched to ensure total system capacitance remains within calibrated parameters for 8 mm sensor drivers.
Q: What insulation material is used to withstand high field temperatures?
A: The cable jacket and conductor insulation utilize FEP material rated for continuous exposure from -35 to +150 deg C in harsh industrial environments.
Q: Is external armor conduit provided on the EZ1900-040 model?
A: No, the EZ1900-040 is a non-armored flexible cable construction designed for installation inside protective conduit or internal cabinet routing.
Field Installation Guidelines
- Inspect the LEMO 1B connectors for cleanliness and absence of moisture before mating field connections.
- Route the 4.0 meter extension cable through dedicated electrical conduit or cable trays away from high-voltage AC lines to prevent induced noise.
- Observe the minimum bend radius of the FEP cable during pull-through to prevent crushing or damaging the inner shield and conductor geometry.
- Hand-tighten connector locking rings securely; wrap field connection joints with self-amalgamating tape if exposed to oil or liquid spray.
- Connect the overall cable shield braid to the dedicated signal ground terminal at the converter end only to prevent ground loops.

Tech & Buying Guide
Industrial Networking Essentials: Demystifying Hubs, Switches, and Routers in Control Systems
Industrial automation relies heavily on robust networking infrastructure to connect programmable logic controllers (PLCs), distributed control systems (DCS), and human-machine interfaces (HMIs). Modern factory automation environments generate vast amounts of real-time operational data across deterministic networks. Understanding the structural differences between hubs, switches, and routers ensures optimal traffic segmentation, minimizes latency, and maintains high network availability.
Safety Relays in Industrial Automation: Fundamentals, Design Standards, and Fail-Safe Architecture
Safety relays form the bedrock of functional safety in modern factory automation, preventing catastrophic equipment failure and protecting plant personnel. While standard electromechanical relays handle basic load switching, they lack the redundant diagnostics required for high-risk industrial environments. Modern industrial automation platforms—including programmable logic controllers (PLCs) and distributed control systems (DCS)—rely on specialized safety relays to monitor field devices and isolate hazards instantly.
Voice-Activated Industrial Automation: Integrating Speech Control into PLC and DCS Architectures
Industrial automation integrates speech recognition, IIoT protocols, and NLP with PLCs and DCS to streamline operations. By leveraging advanced edge computing, engineers enable real-time, hands-free control—allowing personnel to manage smart factory processes safely away from hazardous equipment.
