Use these buttons to explore the different proximity probe solutions available for your specific application:
CTC offers a wide variety of proximity probe driver configurations. Regardless of configuration, all PRO Line drivers come equipped with a buffered BNC that allows the user access to unfiltered voltage data.
The voltage driver has a dynamic voltage output that is compatible with industry-standard continuous vibration monitoring systems and is the format specified in API Standard 670. The dynamic voltage output is proportional to the DC gap between the target material and the probe tip.
4-20 mA DRIVERS:
4-20 mA Drivers Proportional to DC Gap:
Probe showing proportional output for the 4-20 mA signals. With shaft surface at 50 mils, 4-20 output is 12 mA. If the gap increases to 70 mils, 4-20 output will be 16 mA.
Radial Application Drivers:
In radial applications, the probe drivers select the average shaft surface distance and the 4-20 is proportional to the overall peak-to-peak vibration in mils around the average surface of the shaft.
Axial Application Drivers:
In the thrust position the probes auto-range to the face of the shaft or thrust collar and the 4-20 is proportional to the positive or negative vibration away or toward the probe, as shown.
