EPRO PR6423/10R-111 + CON021 High Temperature Explosion-proof Sensor Assembly

The EPRO PR6423/10R-111 matched with CON021 preamplifier forms a high-temperature and explosion-proof eddy current monitoring assembly, specially designed for high-heat, hazardous and ultra-long-distance wiring industrial scenarios. Different from standard probe sets, this 111 version features enhanced high-temperature resistance and Ex ib explosion-proof certification, paired with 10-meter anti-fatigue flexible cable. Cooperated with standard CON021 signal preprocessing unit, the whole system delivers stable anti-interference signal acquisition and linear output, perfectly compatible with MMS6000 TSI systems. It is the preferred solution for vibration and displacement monitoring of turbines, compressors and rotating equipment in petrochemical explosive zones and high-temperature industrial workshops.

1. PR6423/10R-111 Probe Unique Performance & Structural Advantages

PR6423/10R-111 adopts upgraded high-temperature resistant probe structure and industrial stainless steel integrated shell, with optimized internal coil winding and insulation technology. Breaking the temperature limit of ordinary probes, it supports continuous stable operation up to 200℃, effectively adapting to severe heat radiation near high-temperature equipment casings and bearing boxes.

This sensor owns professional Ex ib IIB/IIC explosion-proof certification, suitable for Zone 1 hazardous areas with flammable gas environments. It maintains standard 8mm probe head size and universal thread installation, supporting plug-and-play replacement of conventional PR6423 series probes without on-site structural modification. With stable 2mm linear measurement range and ±1% FS high linearity accuracy, it accurately captures micro vibration and tiny shaft floating of high-speed rotating machinery. The wide frequency response of 4Hz–1000Hz covers equipment low-speed rotation and rated operating conditions, ensuring comprehensive data collection.

2. 10M Flexible Cable High-temperature & Anti-fatigue Characteristics

Equipped with exclusive 10-meter customized flexible cable, PR6423/10R-111 solves long-span wiring demands between field high-temperature equipment and remote control cabinets. The cable adopts high-grade heat-resistant PTFE insulation layer and fatigue-free oxygen-free copper core, resisting long-term high-temperature aging, oil corrosion and mechanical twisting.

The reinforced double-layer shielding structure of tinned copper braid and aluminum foil fully isolates strong electromagnetic interference and ground loop drift in complex industrial environments. After professional factory impedance calibration, the 10-meter long cable achieves zero signal attenuation and distortion-free transmission, perfectly matching the signal input parameters of CON021 preamplifier, avoiding data jitter caused by long-distance signal loss.

3. CON021 Preamplifier Matching & Signal Processing Mechanism

As the dedicated supporting preamplifier for this high-temperature explosion-proof probe set, CON021 undertakes core signal excitation, demodulation and analog conversion work. With IP20 indoor protection grade, it is stably installed in centralized control cabinets, outputting standard -4V~-20VDC linear voltage signals that fully adapt to MMS6000 series TSI system modules.

Built-in reverse connection, short-circuit and overload multi-protection circuits effectively prevent equipment damage caused by on-site wiring errors. It features fast dynamic response and stable frequency decoding capability, which can perfectly restore high-frequency vibration signals collected by high-temperature probes, ensuring real-time and error-free data transmission for high-temperature and hazardous area monitoring loops.
