ROTOMAC^® EDDY CURRENT ROTARIES Eddy Current Rotary Mechanism to Detect Seam Type Defects in Tube and Bar MAC Rotaries use the unique qualities of eddy current rotary probe technology to detect long continuous surface flaws which may not be detected by encircling test coils. Operate with MultiMac^® eddy current electronics. Systems with two, four, or six probes, each with its own detector channel. Accurate Distance Compensation ensures a uniform defect signal, even with off center or out of round material. Choose test headplates for surface or air ride configurations, depending on surface conditions, sizes, and test specifications. Dynamic breaking for quick stop of test probe headplate rotation. Rotary probes, unlike encircling test coils, are not affected by throughput speed changes such as occur in parts forming, because the probes spin continually around the test material at a fixed speed. Operates automatically as defects in the bar or wire create flaw signals, activate alarms, paint markers and other devices. Test magnetic and nonmagnetic material from 1/8″ (3mm) to 7.1″ (180mm) diameter. Method of Choice for Seam Type Defects MultiMac^® eddy current electronics provide the controls, processing and analysis for the Rotary. MultiMac^® can also assign channels to an encircling coil test to detect short, intermittent defects, in combination with the rotary test, where needed. ROTOMAC^® 25RM SLOW THROUGHPUT SPEED ROTARY Cost-Effective Eddy Current Rotary for Testing Wire & Rod The Rotomac^®25 RM is the latest in MAC’s line of eddy current rotaries.  Packaged with our Minimac^® II eddy current electronics, it provides cost effective, reliable on-line inspection for longitudinal surface defects in wire, rod and heavy wall tube, 3 to 25mm diameter.  It is designed for use in cold header operations, spring making, strut rod production and similar slow throughput operations. Operates at 1000 RPM. Throughput speeds up to 12 meters per minute. Out-of-round product can be inspected using our highly accurate distance compensation with absolute test probes. Bushings keep product centered during test. New air ride probe arm design, with convenient, easy access probe adjustment. Standard singe phase AC power input. ROTOMAC^® 20mm HIGH SPEED ROTARY High-Speed Testing of Small Diameter Wire, Rod & Tube for Longitudinal Defects High-speed rotary features include: Operation at speeds up to 18,000 RPM for high production output. Highly sensitive non-contact testing with superior results. New and improved, easy to set up Distance Compensation (a critical factor in testing ovate wire). Simple adjustment tools, with convenient dial-in diameter guide. Two spinning test probes that can be adjusted simultaneously for dimensional changes. Quick twist-on bushing holders. Probes that can be easily centered on the test product’s center of rotation. Simple probe replacement. Meets all applicable safety requirements. The 20mm Rotomac^® HS Rotary delivers high-speed ECT (Eddy Current Testing) for continuous wire operations that include drawing, spring-making, parts forming, and shape and cut. The system is designed to detect longitudinal surface flaws such as seams and laps, in products measuring from 2 to 20mm (0.0787-0.7874”) in diameter Applications Include: Continuous wire operations such as drawing, spring-making, and parts forming lines. Straight and cut operations. Operates in-line with straighteners, or off-line in a separate test station. Ferromagnetic, non-ferromagnetic, and austenitic materials. Tests round and ovate material.

Eddy current encircling and sector test coils are critical for detecting defects and assessing material properties. Each coil type is optimized to provide reliable and accurate performance.

Model 411 Series Dual Probe Followers These followers mount on any standard TacTic^® tester tank. These air-loaded followers ride the material on angulated wheels or balls to ensure excellent following action on crooked materials. TacTic recommends the use of followers on all materials above 1/2″ in diameter. Rugged, lockable calibrated controls enable precise control of the orientation of each transducer. These units can perform normal beam, circumferential or axial scanning. See Bulletin 4110. Model 444 (4-probe) and Model 446 (6-probe) Followers The Model 444 (4-probe) and Model 446 (6-probe) Followers are used for the inspection of billets and large pipes and tubes up to 20 inches in conventional immersion tanks. These Followers use a combination of an air cylinder and an electric motor to lift and lower the scanner to facilitate adjustments and to permit rapid transit along the length of the tank. Model 45 Series Positioners The 45-9 is the most popular system of our extensive line of positioners. It has precise 3-axis control with offset adjustments calibrated to 0.001″ (0.05 mm in the metric model) and rotational to 0.25°. The rotation range about the search tube axis is ± 90°.  See Bulletin 453. Model 140 Series Miniature Manipulators These small manipulators mount on the end of a standard 3/4″ search tube and its bottom connector receives a standard UHF threaded transducer case. Each manipulator provides a ± 54° angulation in one plane only. When the search tube is supported in a positioner such as a Model 45-9, or a Follower such as a Model 444, this angulation is sufficient for the detection of defects of almost any orientation. If you need another rotation axis, these units may be connected in Series with 90° rotation between them. See Bulletin 1400.

Model 28B Alarm and Motor Control Center The Model 28B Alarm and Motor Control Center, mounted on the front of almost all TacTic Testers, includes variable speed drive motor control with the important “STOP ON DEFECT” and variable alarm horn functions. It also provides scan direction outputs to prevent misoperation of a strip-chart recorder or a TacTic Model 1088 Indicator/Controller during drive direction reversals. See Bulletin 760B. Model 14D-Coded Alarm TacTic developed special interface devices such as the Model 14D–Coded Alarm to meet unique system needs. This multi-channel audible alarm has distinct channel tone patterns that help the operator identify which channel has produced an indication. Model 1088A Test Parameter Indicator & Marker/Sorter Controller The Model 1088A Test Parameter Indicator & Marker/Sorter Controller provides all Model 108 functions plus computer-controlled delayed alarms to operate “downstream” defect marking or sorting devices. Adjustable “dead zones” are included to prevent false operation from signals due to piece ends passing the transducers. The TacTic Model 1088A Test Parameter Indicator calculates and displays feed rate and correct settings for conveyor parameters such as drive, idler, and support pedestal wheel angles. It is used when entering the material diameter and desired scan index, or “pitch,” on the keypad for a menu-selected device. Infrared sensors measure throughput rate and enable digital display and limit alarms for linear and surface velocities and scan pitch. ORDER REPLACEMENT PARTS
