Frequently Asked Questions (FAQ)
-
What is the primary function of the PR6426/010-130 sensor?
It measures shaft displacement and vibration in non-contact mode using eddy current principles. -
What is the significance of the CON021 converter?
It processes and converts the analog signal from the PR6426 probe into a usable output for control or monitoring systems. -
Can I use this sensor in high-temperature environments?
Yes, the probe operates effectively up to 180°C, making it ideal for turbines and other heat-intensive machinery. -
Is the sensor tip replaceable?
No, the sensor is factory-sealed and the tip is not user-replaceable. -
What mounting threads are available for the PR6426/010-130?
The standard mounting thread is M14x1.5, but other thread types may be available upon request. -
What is the recommended cable length for signal integrity?
Typically, cable lengths of up to 10 meters are supported without degradation, but this depends on the system setup. -
Is the PR6426/010-130 compatible with older CON011 converters?
While it is optimized for use with CON021, some backward compatibility may exist depending on the application. -
Does it require external power?
Power is supplied via the converter unit (CON021), which is typically integrated into a monitoring system. -
Can the sensor be used in hazardous locations?
Yes, certified ATEX versions of this model are available for use in explosive environments. -
How is the sensor calibrated?
Sensors are factory calibrated. In-field calibration is generally not required but verification against known displacement standards is possible.
