Présentation du produit
The Epro CON020/T4 + PR6424/01 16 mm Eddy Current Sensor is a factory-matched, non-contact displacement and vibration measurement system designed for critical rotating machinery. The package combines a PR6424/01 proximity probe (16 mm sensing tip) with the CON020/T4 signal converter, providing a conditioned 4–20 mA (or optional 0–20 V DC) output proportional to shaft position or dynamic vibration.
Developed for turbines, compressors, and other high-value assets, the system delivers stable linear performance across a wide temperature span, resists electromagnetic interference, and thrives in oily, contaminated environments typical sur power-generation and petrochemical plants.

FAQ
-
What is the default output sur the CON020/T4 converter?
A calibrated 4–20 mA signal proportional to shaft displacement; voltage mode can be enabled via jumper. -
Can I interchange this probe with a different CON020 variant?
No—the PR6424/01 is calibrated exclusively with its shipped CON020/T4. Mixing pairs invalidates accuracy. -
How does cable length affect sensitivity?
Length is included in the factory calibration; replacing or shortening the cable changes the transfer function. -
What is the maximum allowable vibration amplitude before clipping?
The linear range extends to ±2 mm; excursions beyond will saturate the converter output. -
Does the system support dynamic vibration (AC) and static position (DC) simultaneously?
Yes—the converter superimposes the dynamic AC component on the DC bias for holistic monitoring. -
Is reverse-polarity protection built in?
Yes, the converter incorporates diode protection to prevent damage from wiring errors. -
Can the sensor be installed in an ATEX Zone 1 gas atmosphere?
An Ex ia certified version is available when ordered with the proper option code. -
What is the maximum loop impedance for 4–20 mA operation?
Up to 600 Ω at 24 V DC supply; derate linearly with lower supply voltages. -
How is temperature drift compensated?
The CON020/T4 uses precision thermocompensation networks to keep drift below ±0.25 % FS/100 °C. -
Can I split the 4–20 mA signal to two receivers?
Yes, provided the total loop resistance (both receivers plus wiring) stays within the specified limit.
