Features:
- Captures radial and axial shaft displacement, position, eccentricity, speed, and key signals through non-contact eddy current measurement.
- Combines a 20 kHz converter frequency range with a rise time below 15 µs for fast response to dynamic machinery conditions.
- Provides an IP66 sensor, high-temperature cable construction, armored protection, and secure Lemo connectivity for demanding industrial installations.
Stable shaft monitoring plays an important role in protecting high-value rotating equipment from developing mechanical problems. Emerson PR6423/018-010 CON021 supplies continuous non-contact measurement without adding friction or loading to the rotating surface. Operators can use the resulting signals to observe shaft position and dynamic movement during normal operation. Early recognition of changing behavior supports more informed maintenance decisions and improved machinery availability.
Mechanical and electrical elements are coordinated as one measurement chain in Emerson PR6423/018-010 CON021. The 8 mm probe senses changes at the shaft surface, while the CON021 converts the sensor response into a usable output signal. Fast signal processing helps preserve information generated by rapidly changing shaft motion. Such performance benefits turbine, compressor, pump, gearbox, and fan monitoring systems requiring dependable dynamic measurements.
Installation flexibility strengthens the practical value of Emerson PR6423/018-010 CON021 in retrofit and maintenance projects. The M10 × 1 sensor case, 105 mm threaded section, armored 5.0 m cable, and self-locking Lemo connection support secure mechanical integration. Converter screw terminals accommodate power and output conductors up to 1.5 mm², while the supplied mounting screws simplify enclosure installation. Durable materials and broad operating-temperature limits make the kit suitable for demanding machinery environments.
The PR6423/018-010 CON021 Emerson 8mm Eddy Current Sensor & Signal Converter Kit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Built-in Tuning Firmware: The preamplifier CON021 incorporates dedicated tuning firmware specifically designed for the high-frequency excitation characteristics of the 8mm probe, ensuring stable signal gain within the 2.0mm standard linear range.
- Linearization Algorithm: The firmware is pre-programmed with a standard ferromagnetic steel (42CrMo4) response curve algorithm, enabling high-precision, delay-free digital linearization of micron-level gap variations.
- Dynamic Characteristic Optimization: The firmware algorithm optimizes amplitude-frequency characteristics across the 0 to 20,000 Hz frequency range, minimizing phase distortion during high-frequency vibration signal transmission.
- Zero-Point Temperature Drift Compensation: The firmware incorporates specific temperature coefficient compensation logic, which, in conjunction with the probe hardware, strictly limits temperature errors to an extremely low range compliant with API 670 standards.
- Probe Operating Temperature: The PR6423 8mm probe and cable feature an IP68 anti-permeability design, enabling long-term stable operation in extreme high and low temperature cycles ranging from -35°C to +150°C.
- Converter Protection Rating: The CON021 pre-signal converter housing has an IP20 protection rating, suitable for installation in control cabinets, instrument boxes, or industrial indoor environments with basic dust protection.
- Pressure-Resistant and Corrosion-Resistant Housing: The probe's metal sheath is made of high-grade stainless steel, with excellent resistance to industrial oil corrosion and the ability to withstand internal bearing housing pressures up to 10,000 hPa (approximately 145 psi).
- Vibration and Shock Resistance: The entire assembly (probe and converter) has passed a 5g @ 60Hz (at 25°C) mechanical vibration test, adapting to high-vibration industrial environments.
- Small and Medium-Sized Rotor Vibration: Due to its small 8mm diameter head design, lateral clearance is minimal, making it ideal for radial vibration measurement of large and medium-sized or small and medium-sized rotating machinery with shaft diameters between 50mm and 80mm.
- Steam Turbine Keyphase Trigger: Commonly used as a keyphasor sensor, it captures pulses from keyways or protrusions on the main shaft, providing accurate speed and phase references for DCS systems.
- Multistage Pump Axial Displacement: Widely used in high-speed equipment such as power plant feedwater pumps and chemical multistage centrifugal pumps, it monitors the axial movement of thrust bearings in real time to prevent serious accidents caused by friction between moving and stationary parts.
- Space-Confined Bearing Housings: Compared to the 16mm large probe, this 8mm kit is easier to wire and mount within the compact structure and extremely limited internal installation space of small industrial turbine or fan bearing housings.
