Information
- A 70 mm threaded case provides additional mounting reach while the 9 m extension carries the signal to the converter. The longer body changes the mounting geometry; it does not increase the electrical measurement range of the 10 m transducer chain.
Cable chain: 1 m probe lead + 9 m armoured extension
Converter matching: 10 m complete electrical length
The EZ1901 extension contributes 9 m to the 10 m chain. A compatible EZ1000 converter must be calibrated for the complete assembly and intended target. The nominal scale factor is 8 V/mm for ISO calibration or 7.87 V/mm for API calibration; a 1.5 mm nominal gap is a reference point within the matched system.
The 10 m electrical chain uses the general recommended dynamic range of no more than 1250 µm peak-to-peak. The separate 2000 µm recommendation for a standard 5 m API-calibrated chain must not be assigned to this configuration. Probe and integral cable operation is -35 to +180 °C, while extension cables and connectors are limited to -35 to +150 °C.

Application scope: A 70 mm threaded case provides additional mounting reach while the 9 m extension carries the signal to the converter. The longer body changes the mounting geometry; it does not increase the electrical measurement range of the 10 m transducer chain.
Relative shaft vibration
Observe target displacement through the complete calibrated eddy-current chain.70 mm mounting body
Use the selected case geometry to position the 8 mm sensing tip while retaining the fixed neck clearance.9 m cable reach
Route the armoured extension to the converter without changing the 10 m total electrical length.Static position measurement
Set and verify the target operating point using the matched converter output and intended calibrated range.
Do not cut or splice the 10 m chain or exchange extension lengths without matching calibration.
Maintain the specified target area, surrounding-metal clearance and fixed neck clearance.
Limit EZ108x locknut torque to 15 N·m and prevent cable twisting.
Keep extension cables and connectors within +150 °C even if the probe location permits +180 °C.
Use the specified hand-tightened connection and heat-shrink insulation; apply additional hazardous-area requirements where relevant.
Verify gap, target response and channel indication before restoring machinery monitoring.

Technical notes
Signal relationship: Total electrical length is 1 m + 9 m = 10 m. Mechanical case length does not change this calculation and does not establish the displacement range.
Installation boundary: Keep the armoured cable bend radius at least 35 mm and stored loop diameter at least 100 mm. Avoid continuous oil immersion and direct oil-stream exposure; leave allowance for installation and thermal movement.
Technical basis: Emerson AMS EZ 1000 Sensor Installation Guide, MHM-97883 Rev. 1.09, January 2025. The order-code tables map the 70 mm EZ1081 probe and 9 m EZ1901 extension to a 10 m chain. Performance remains conditional on target and matched converter calibration.
FAQ View All FAQ
-
Does the 70 mm case in EZ1081-07-00-010 + EZ1901-090 increase displacement range?No. Case length controls mounting reach. The 8 mm sensing tip and matched 10 m electrical chain determine the measurement response.
-
What makes the EZ1901-090 section of EZ1081-07-00-010 + EZ1901-090 an armoured extension?EZ1901 identifies the protected extension-cable construction and 090 selects 9 m. Together with the 1 m integral lead it produces a 10 m chain.
-
How much target material should be present behind the measurement area of EZ1081-07-00-010 + EZ1901-090?A target-material thickness of 12 mm is recommended for the specified sensor geometry. Thin targets can change the response and require an appropriate application assessment.
-
Why should EZ1081-07-00-010 + EZ1901-090 face the target as nearly square as possible?Probe tilt changes the measurement geometry. The installation guidance recommends an angle below 4° for the stated low scale-factor deviation condition.
-
What happens if the 10 m lead path of EZ1081-07-00-010 + EZ1901-090 is shortened on site?The calibrated electrical length changes. Do not cut or splice the probe or extension cable; select and calibrate the required complete combination.
-
Which sensitivity convention applies to EZ1081-07-00-010 + EZ1901-090?The system uses 8 V/mm for ISO calibration or 7.87 V/mm for API calibration. The actual converter calibration and target must be identified before selecting a scale factor.
-
How should the longer case of EZ1081-07-00-010 + EZ1901-090 be secured during tightening?Support and hold the probe case, keep the fixed tip neck clear and limit locknut torque to 15 N·m. Do not transmit tightening torque into the cable.
-
Can EZ1081-07-00-010 + EZ1901-090 be installed over a very small target face?Target area influences the response. The measurement-area diameter should be at least 14 mm, with more than 20 mm recommended for the stated low-error geometry; evaluate the actual shaft or target before installation.
