01
A Measurement Chain Built Around the Shaft
The PR6426/010-030 is a non-contact eddy-current sensor for measuring radial and axial shaft displacement, position, eccentricity and motion. Paired with the CON021/916-160 converter, the assembly provides an extended measuring range for compatible PR6426 applications.

Signal converter
The converter conditions the probe signal and supplies a voltage output for the connected monitoring equipment.
02 / SENSOR CHARACTERISTICS
PR6426 Probe Profile
Parameter Specification
Sensor family PR6426, 32 mm eddy-current sensor
Measurement method Non-contact eddy-current
Sensitivity 2 V/mm (50.8 mV/mil), ≤ ±1.5% max.
Static range ±4.0 mm
Target material Ferromagnetic steel, 42CrMo4 standard
Operating temperature -35 to 175°C
Sensor cable PTFE cable; typical overall lengths 4, 5, 8 and 10 m
The exact probe cable, armor, mounting and termination configuration should be matched to the installed part.

05 / REPLACEMENT NOTES
Three Details Worth Checking
A
Probe cable and termination
Check the installed cable length, armored or non-armored construction, adaptor plug and LEMO/open cable-end arrangement.
B
Measuring range and monitor scaling
The 16 mm extended range belongs to CON021/916-160. Confirm the receiving monitor's scaling and alarm configuration before commissioning.
C
Output and supply wiring
Verify the converter output mode, supply polarity and receiving input range to avoid scaling or wiring mismatch.
06 / FAQ
Engineering Questions
Q1. What changes when CON021/916-160 replaces a standard-range PR6426 converter?
A. The 916-160 variant provides a 16.0 mm extended measuring range with a maximum linearity error of 2.0%. The monitoring channel's engineering-unit scaling and alarm thresholds should be checked against the replacement measurement chain.
Q2. Does PR6426/010-030 use the same sensor range as CON021/916-160?
A. No. The PR6426 sensor specification gives a static range of ±4.0 mm, while 16.0 mm is the extended measuring range specified for the CON021/916-160 matched converter configuration. They describe different parts of the measurement chain.
Q3. Why is the target shaft material important when using PR6426/010-030?
A. Eddy-current response depends on the electrical and magnetic properties of the target. The PR6426 specification uses ferromagnetic steel 42CrMo4 as its standard target material. A different shaft material may require a separate calibration check.
Q4. What could cause a stable but offset reading after installing CON021/916-160?
A. Check the initial probe gap, target surface material, converter output mode, monitor input scaling and wiring polarity. A stable offset may result from an incorrect mechanical gap or a mismatch between the converter output and monitor configuration.
Q5. Can the cable on PR6426/010-030 be shortened or replaced independently?
A. Do not assume that a field cable alteration preserves the calibrated measurement chain. Check the complete probe configuration, cable construction and termination before changing the installed assembly.
