PIAB Dynamometers

PIAB Dynamometers

The PIAB Dynamometer is excellent for measurement and control of tension forces, where accuracy, reliability and safety in all conditions is required.

• The PIAB Dynamometer is extremely robust and reliable instrument and is an all-weather instrument.

Technical Data

Range of Application

• The PIAB Dynamometer is an all-weather instrument, equally suitable for use in the laboratory as out in the field for weighing and measuring mechanical forces.

Function

• The pull rod movement operates the scale drum through a square thread stem.
• The power-absorbing element consists of specially made Belleville type spring washers, designed to be entirely free from wear. The spring washers cannot be overloaded.

Safety

• Safety factor 5:1, guaranteed to withstand a load of 5 times full scale reading before rupture.
• The resistance to rupture is tested by the National Swedish Institute for Materials Testing.
• The PIAB Dynamometer may be overloaded by 100% without impairing the accuracy.
• The PIAB Dynamometers, types M-G, have drop-forged steel eye brackets (SIS 2174, St 52-3N acc. to DIN 17100, 50 D acc. to BS 4360); giving a guaranteed impact resistance to -20°C.
• The O-ring of the pull rod is protected by a neoprene rubber membrane.
• On instantaneous unloading, e.g. breaking test, the return movement of the pull rod is retarded by a specially made spring washer.
• The PIAB Dynamometer is approved by the National Board of Occupational Safety and Health for integral connection in the carrying system of a lifting device and for weighing of test loads in connection with inspection.

Dynamometer for Remote Reading

• The PIAB Dynamometer used for remote reading is supplied with a builtin precision potentiometer. The potentiometer is directly connected to the scale mechanism of the PIAB instrument.
• The electrical resistance of the potentiometer varies in proportion to the load on the dynamometer.
• The resistance is indicated on a receiving instrument, calibrated individually and marked with the same serial number as the dynamometer.
• The electrical connections are made on a connection block in a surface mounted connection box.

Contact Function

• The PIAB Dynamometer can be equipped with a built-on adjustable Switch Head.
• Using a Microswitch, which is directly influenced by the pull rod, the PIAB Dynamometer gives an electrical contact function at a preset value.
• For further technical specifications please refer to PIAB Info 9116-1 PIAB Switch Head Dynamometer.

Protection against Corrosion

• The PIAB Dynamometer is fully pressure tight and each instrument is pressure tested.
• The external surfaces are zinc plated with clear chromate passivation.
• If the PIAB Dynamometer is to be used in a very corrosive atmosphere, it can be polyester lacquered.
