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.
