AOIP Micro-Ohmmeters are applying in Earth bonding and Metallization tests

  • Customer: AIRBUS aircraft part production suppliers
  • Goal: riveting door test / verify earth bonding
  • Equipment: OM16
  • Application: earth bonding and metallization.
  1. Measure under 10A with high resolution 0,1µohm.
  2. Small diameter kelvin test probes.
  • Software is used in order to proceed to test onsite , save values and download when back to the office.
  • Reproducibility: All parts of an aircraft, from flight commands to the undercarriage must be tested in earth bonding and continuity.
  • All aircraft sub manufacturers must follow the rules

  • Customer: EUROCOPTER (EADS group)
  • Goal: verify that no electrostatic charges is stored on a particular points. NO CHARGE = NO EXPLOSION
  • Equipment: OM16
  • Application: earth bonding and metallization. Metallization is performed between several points of the aircraft or helicopter.
  1. Metal part: Test under 10A (not more than 10A)
  2. Composite part : Test under 1A (< 1A)
  • For convenience, the OM16 has been modified to offer a removable top: It was easier to use in small volume as a cockpit of an helicopter.

Aoip Micro-Ohmmeters are applying in Carbon brush control

  • Customer: Motor manufacturer
  • Goal: control of carbon brushes
  • Equipment: 2 x OM16 + Kelvin test probes
  • Application:
  1. On a motor when current is crossing the brushes, a temperature rising can occur and the carbon brushes can melt, the resistance value must be very low. 
  2. With OM16, a test can be performed on manufacturing process, threshold values are programmed and if one of them is crossed, the beeper indicates it to the operator.
  • Test installed on a production site

AOIP Micro-Ohmmeters are applying in Welding lead control

  • Customer: PSA, Renault
  • Goal: cable test between power supply and the welding clamp of robot / preventive maintenance
  • Equipment: OM16
  • Application:
  1. The resistance measurement allows to determine the state of wear of cable. In this way it is possible to replace only the cable damaged.

AOIP Micro-Ohmmeters are applying in Coil test

  • Customer: ITT Automotive
  • Goal: coil test of solenoid valve
  • Equipment: OM16
  • Application:
  1. The value of coil resistance must be located between two values. Two thresholds are setup, on the production line when test is performed if the operator hears a beep, the product is  rejected.

AOIP Micro-Ohmmeters are applying in Quality test

  • Customer: LEGRAND
  • Goal: circuit breaker quality test
  • Equipment: OM21
  • Application:
  1. Check whether the resistance of each pole of the circuit breaker is in the specified values.
  • Test in end of production line

AOIP Micro-Ohmmeters are applying in Length cable test

  • Customer: NEXANS
  • Goal: verify the resistance of cable coil
  • Equipment: OM21
  • Application:
  1. Determine the real length of cable
  • Before the shipment
Calculation:
L = Rm / RL
Rm= measured resistance
RL= linear resistance
The linear resistance is
knew by manufacturer.

AOIP Micro-Ohmmeters are applying in Maintenance
  • Customer: RTE (Network Electricity Transportation France)
  • Goal: Bonding / Earthing in substations
  • Equipment: OM10 and OM16
  • Application:
  1. In substations, bonding and earthing connections must be regularly measured to ensure safety, i.e. to achieve and maintain low resistance joint: Copper earthing systems are found on every equipment in substations and must be regularly controlled, as well as the electrical connection between components that must remain at the same potential.
