4-20 mA HART Loop Protocol and Channel Isolation
The CON021 signal converter conditions high-frequency magnetic field perturbations generated by the PR6423 sensor tip into a high-fidelity analog voltage output (-2 VDC to -18 VDC linear window). Designed for integration with upstream TSI and DCS platforms, the driver circuit includes high channel-to-channel isolation and low-pass filtering. This design prevents common-mode noise and cross-talk from nearby 4-20 mA HART loops or high-voltage lines, ensuring reliable telemetry in high-EMI power generation and turbine environments.
Frequently Asked Questions
Q: What physical features distinguish the /010-010 configuration from armored probe variants?
A: The /010-010 suffix designates a 1.0-meter integral probe lead without flexible stainless steel armor conduit, making it suitable for internal bearing housings or applications utilizing external protective tubing.
Q: How is the correct installation air gap verified electrically during setup?
A: Set the mechanical gap to approximately 0.5 mm, then verify that the CON021 signal output rests within the middle of its linear voltage band (typically around -10 VDC gap voltage) prior to locking down the mounting threads.
Q: What material properties are required for the target surface?
A: Calibrated system sensitivity relies on a standard ferromagnetic steel target, specifically 42CrMo4 (AISI/SAE 4140), with a minimum shaft diameter of 25 mm.
Field Installation Guidelines
- Mount the PR6423 threaded stainless steel sensor body into the bearing housing casing using a rigid bracket to minimize mechanical vibration.
- Advance the probe toward the shaft until the static gap measures 0.5 mm or the driver output reads -10 VDC gap voltage.
- Route the 1.0 m integral PTFE lead through clean cable paths, avoiding sharp metal edges or tight bends that exceed minimum bend radius limits.
- Fasten the CON021 converter onto an aluminum DIN-rail inside a sheltered junction box, ensuring low-resistance cabinet earth bonding.
- Connect probe extension cables to the CON021 terminals, anchoring cable drain shields to a dedicated system earth point to eliminate ground loop currents.

Tech & Buying Guide
Understanding Modern SCADA Systems: Architecture, Communication Topologies, and Industrial Applications
Supervisory Control and Data Acquisition (SCADA) systems form the digital backbone of modern industrial automation. They collect critical field data, transmit signals across vast distances, and empower plant operators with real-time process visibility. Across modern infrastructures, SCADA solutions streamline centralized control and maintain continuous operational uptime.
Understanding OPC Servers in Modern Industrial Automation: Principles, Architecture, and Applications
In industrial automation, connecting physical hardware with high-level software remains a primary operational challenge. Factories utilize programmable logic controllers (PLCs), distributed control systems (DCS), human-machine interfaces (HMIs), and smart sensors from diverse vendors. These devices often speak different proprietary protocols. Open Platform Communications (OPC) servers solve this interoperability challenge by standardizing how data flows across factory networks.
Industrial Fiber Optic Cables: Principles, Connectors, and Fusion Splicing Techniques
Modern factory automation relies heavily on fiber optic cables for high-speed industrial data transmission. Fiber optic cables transmit light pulses instead of electrical signals, eliminating electromagnetic interference (EMI) risks completely. Each optical strand consists of a high-purity glass core surrounded by a protective cladding layer. The difference in refractive index between core and cladding enables total internal reflection. Protective resin buffers, Kevlar strength members, and rugged outer jackets safeguard delicate glass cores in harsh environments. Consequently, automation engineers prefer fiber backbones for reliable noise-free communication in industrial control systems.
