Product Overview
The CON021 + PR6423/01C-030 is a combined eddy-current proximity sensor system designed for high-fidelity measurements of shaft displacement, vibration, eccentricity and related dynamic properties in rotating machinery. The system consists of the PR6423 sensor probe and the CON021 signal converter. It is suitable for demanding turbomachinery environments, offering non-contact measurement, high precision, rugged build, and compatibility with safety, hazardous area requirements.
Technical Specifications
| Parameter | Value | Notes / Conditions |
|---|---|---|
| Model | CON021 + PR6423/01C-030 | Sensor + Converter system |
| Sensor Type | Eddy current displacement (non-contact) | Measures radial & axial shaft motion, eccentricity, speed, etc. |
| Tip Diameter | 8 mm | Diameter of probe tip of PR6423 sensor |
| Thread / Case Housing | M10 × 1 thread | Metric thread mounting standard |
| Linear Measurement Range | 2 mm (≈ 80 mils) | Standard range for PR6423 sensor in this version |
| Initial Air Gap | 0.5 mm (≈ 20 mils) | Distance between probe tip and target at installation |
| Incremental Scale Factor (ISF) | ≈ 8 V/mm ±5% | Based on standard temperature (0-45 °C) |
| Deviation from Best-Fit Straight Line (DSL) | ±0.025 mm (±1 mil) | Over the linear measurement range at ambient conditions |
| Minimum Shaft / Target Diameter | 25 mm | Smaller diameters increase measurement error significantly |
| Target Material | Ferromagnetic steel (e.g. 42CrMo4 or similar) | Ensures designed electrical and magnetic response |
| Converter Frequency Range (-3 dB) | 0 … 20,000 Hz | Converter (CON021) dynamic response |
| Converter Rise Time | < 15 µs | How fast the converter output responds to input changes |
| Converter Supply Voltage | −23 V to −32 V DC (for one output range), or −21 V to −32 V DC (alternative output range) | Operating range depends on the implementation/output range used |
| Operating Temperature, Converter | −30 °C … +100 °C | For CON021 module |
| Operating Temperature, Sensor + 1 m Cable | −35 °C … +180 °C | Full sensor system under standard cable lengths |
| Operating Temperature, Cable & Connector | −35 °C … +150 °C | Cable/connector limited by materials used |
| Protection / Sealing (Sensor) | IP66 (IEC 60529) | Sensor and cable protection from dust/water ingress |
| Weight | Converter module ~120 grams | Sensor weight (with 1 m cable) around 100 grams in typical non-armored version |
| Converter Output Signal Range | −4 V to −20 V (with one supply range), or −2 V to −18 V with alternate supply | Depending on converter configuration and supply voltage |
| Housing Materials | Sensor tip: PEEK; Sensor case: stainless steel; Cable insulation: PTFE; Connector: brass nickel-plated | Ensures durability in high temperature / harsh environments |
