      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • A 1 m armoured probe and 4 m armoured extension establish the standard 5 m measurement chain. This combination is particularly relevant when the installed EZ1000 calibration uses the 5 m API reference arrangement.
      Probe configuration: 8 mm tip, M10 × 1, 40 mm case
      Cable chain: 1 m probe lead + 4 m armoured extension
      Converter matching: 5 m complete electrical length
      The EZ1081 probe uses a GF30 PEEK sensing tip, stainless-steel body and protected cable construction. Its selected 40 mm case has the ordered unthreaded section set to 00. A fixed 5 mm neck remains behind the tip and must not be treated as available mounting thread.

      The EZ1901 extension contributes 4 m to the 5 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 standard 5 m combination supports the special 2000 µm peak-to-peak recommendation only with the specified API calibration on 42CrMo4. Other configurations use the stated general 1250 µm peak-to-peak recommendation. Probe and integral cable operation is -35 to +180 °C, while extension cables and connectors are limited to -35 to +150 °C.
      Controller platform reference: AMS EZ 1000 transducer system. Match the complete 5 m chain and target calibration.
      Technical material for Emerson EZ1081-04-00-010 + EZ1901-040 covers probe construction, 40 mm case selection, 4 m armoured extension and calibrated-chain limits. The separate installation guide covers 40 mm mounting, 5 m chain identification, armoured cable routing and target-response verification.
      Original manufacturer pages retain their technical context. Use the Apter Power guide with the applicable manufacturer instructions and approved installation design.
      System and supply context: Use the stated probe and extension with an EZ1000 converter calibrated for 5 m and the intended target. The converter, mounting hardware and protection monitor are separate items.

      Application scope: A 1 m armoured probe and 4 m armoured extension establish the standard 5 m measurement chain. This combination is particularly relevant when the installed EZ1000 calibration uses the 5 m API reference arrangement.
      Prepare Emerson EZ1081-04-00-010 + EZ1901-040 for its configured installation using these checks.
      Preserve electrical length

      Do not cut or splice the 5 m chain or exchange extension lengths without matching calibration.

      Keep the tip clear

      Maintain the specified target area, surrounding-metal clearance and fixed neck clearance.

      Control torque

      Limit EZ108x locknut torque to 15 N·m and prevent cable twisting.

      Separate temperature limits

      Keep extension cables and connectors within +150 °C even if the probe location permits +180 °C.

      Protect the joint

      Use the specified hand-tightened connection and heat-shrink insulation; apply additional hazardous-area requirements where relevant.

      Check the operating point

      Verify gap, target response and channel indication before restoring machinery monitoring.

      Alternative Names

      Technical notes

      Signal relationship: Total electrical length is 1 m + 4 m = 5 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 40 mm EZ1081 probe and 4 m EZ1901 extension to a 5 m chain. Performance remains conditional on target and matched converter calibration.

      FAQ View All FAQ

      • How does the cable combination in EZ1081-04-00-010 + EZ1901-040 produce a 5 m chain?
        The EZ1081 probe contributes a 1 m integral lead and EZ1901-040 adds 4 m. The converter must be calibrated for that complete 5 m combination.
      • When can EZ1081-04-00-010 + EZ1901-040 use the 2000 µm peak-to-peak recommendation?
        That recommendation is specific to the standard 5 m chain with a 1 m probe cable, 4 m extension and API calibration on 42CrMo4. It is not a universal rating for every target and calibration.
      • What does the 04 case option specify in EZ1081-04-00-010 + EZ1901-040?
        It selects a 40 mm probe case. The separate 00 option sets the ordered unthreaded case section to zero; the fixed neck at the sensing tip still requires clearance.
      • Why does EZ1081-04-00-010 + EZ1901-040 require a matched EZ1000 calibration?
        The probe, extension and converter operate as one measurement chain. Electrical length, target material and calibration convention affect scale factor and usable range.
      • Which bend radius applies to the armoured cable in EZ1081-04-00-010 + EZ1901-040?
        The minimum bend radius for armoured cable is 35 mm. When storing a loop, keep the coil diameter at least 100 mm.
      • Does the full EZ1081-04-00-010 + EZ1901-040 assembly share the probe tip temperature limit?
        No. The probe with its 1 m cable is specified from -35 to +180 °C, but the extension cable and connectors are limited to -35 to +150 °C.
      • How should the connector joint in EZ1081-04-00-010 + EZ1901-040 be insulated?
        Tighten the connection by hand and install the specified black heat-shrink insulation. Additional hazardous-area provisions apply when required by the installation.
      • What sensor-face clearance should be retained around EZ1081-04-00-010 + EZ1901-040?
        Avoid nearby metallic objects within the probe clearance zone. The 8 mm sensor geometry uses a recommended free diameter of at least 24 mm around the sensing region; the actual mounting drawing and target geometry must agree.
