INTROS-AUTO

General Information

INTROS-AUTO designed for non-destructive inspection of steel wire ropes with automatic data interpretation. Results of automatic data interpretation display in “traffic light” mode. Green light informs the operator the opportunity to continue rope operation; yellow light warns against certain level of rope deterioration – both LMA and LF, and is adjustable; red light alerts that rope may no longer be used. Following criteria used to analyze actual condition of rope – number of broken wires within certain rope length, loss of metallic cross section area in percentage, and speed of rope degradation. All inspection data are available at any time for manual interpretation by inspector. The instrument is currently successfully operated at on-shore drilling rigs, it can be also used for variety offshore and onshore installation. INTROS-AUTO can be connected to external computer for continuous wire rope monitoring.

INTROS-AUTO consists of magnetic heads and control and display unit mutually connected with cable up to 80 m in the length. The software (Wintros-Auto, Intros-Auto Monitor) is delivered with the INTROS-AUTO.

Control and display unit is designed for processing inspection data, detecting defects and their location along the rope, automatic data interpretation and displaying results in “traffic light” form, i.e. by means of switching one of LED – green, yellow, or red.

Green light is on, if rope condition is satisfactory.

Yellow light warns about certain level of deterioration, close to discard criteria. This level is adjustable.

Red light alerts, that discard criteria is reached, i.e. rope is in bad condition.

Following criteria considered during interpretation and displaying inspection results: number of broken wires within certain rope length, loss of metallic cross section area in percentage, and speed of rope degradation. To evaluate rate of degradation change, currently obtained inspection data are compared with the data, obtained during previous inspections.

The unit is powered with DC 12V, has wireless connection with PC, and following features:

dimensions 350 х 150 х 150 mm;
weight 3 kg;
ingress protection level IP65.

Magnetic head has magnetic system with strong permanent magnets; implemented non-detachable measuring set is equipped with Hall Effect sensors and coils. Both magnetic system and measuring set have been properly optimized to achieve accurate LMA measurement and detect outer and inner broken wires. Outside rollers enable to exactly align the rope inside the magnetic head for better performance and protection of inner surface of the head from abrasive wear. Optional odometer can be fixed on the magnetic head for measuring traveling distance. All magnetic heads have ingress protection level IP 66. The list of currently available magnetic heads is shown in the below table. The instrument can be customized for monitoring ropes up to 135 mm in diameter.

MH size	Rope diameter, mm	Weight, kg
МН 6-26A	6 to 26	4
МH 25-31	28 to 31	20
МH 31-35	31to35	20
МH 35-42	35 to 42	30
МH 42-52	42 to 52	30
МH 52-64	52 to 64	30
МH 60-72	60 to 72	60
МH 72-85	72 to 85	60

Wintros-Auto is intended for downloading and processing data, obtained during wire rope inspection with INTROS-AUTO. Functions of Wintros-Auto are similar to the functions of software Wintros.

Intros-Auto Monitor enables adjusting INTROS-AUTO, such as calibration, setting of discard criteria, thresholds for warning level (yellow light), etc. as well as on-line displaying of the rope trace with automatic data interpretation. Intros-Auto Monitor is included into the delivery set for each instrument INTROS-AUTO.

Both Wintros-Auto and Intros-Auto Monitor work under Microsoft Windows XP/Vista/7/8.1.
