Torque tester offers wide application range
Cost-effective yet reliable in-house testing and calibration of all types of torque wrench from 2 to 1500Nm is now possible with the Professional Torque Tester (Pro-Test) from Norbar Torque Tools.
Torque tool tester can be specified for many uses
Torque tool tester - a highly specified but easy to use instrument which, when connected to appropriate transducers, is ideal for a huge range of torque testing applications up to 100,000Nm.
The PT52 is available in two torque capacities - either 1000Nm with a maximum speed of 125rpm, or 600Nm with a maximum speed of 200rpm.
There are two torque control methods - stall and electronic shut-off.
The stall tool is the basic version and torque control is achieved by adjustment of the inlet air pressure.
An air pressure versus torque graph unique to each tool allows specific torque values to be set.
The electronic shut-off version includes a torque transducer, torque display and internal solenoid valve.
The desired torque tolerance band is set on the tool and once the lower limit is achieved, the valve cuts the air supply.
The actual torque delivered to the joint is displayed on the tool along with pass / fail indication light.
The exceptionally compact 52mm diameter gearbox provides excellent access to bolts and improves tool balance.
Weighing just 3.8kg for a single direction stall tool and 4.0kg for a bi-directional version, it is light and comfortable to use.
Apart from weight reduction, the design paid much attention to ergonomic factors such as handle angle and trigger reach.
Norbar has already experienced strong sales for the PT52 with applications including: valve and pipe work maintenance in replacement of 3/4in drive impact wrenches, assembly of off-road machinery and truck and bus wheel bolting.
Wheel bolting is a particularly interesting area because the traditional method has involved using an impact wrench to run down the nut at high speed followed by a torque wrench for accurate tightening.
The PT52 gives the option of a single tool with both speed and accuracy while having low vibration and noise levels.
Norbar Torque Tools is Europe's leading manufacturer of torque tightening and measuring equipment and the PT52 is the latest high technology addition to the extensive Pneutorque range, which includes models up to 100,000 Nm.
To further enhance the availability of Norbar products, a number of specialist regional distributors are being appointed providing nationwide coverage.
