TORQUE SENSORS

INTRODUCTION:

A torque sensor is a device that measures and records the torque of a rotating system. A torque sensor’s working principle is such that transducers are used to convert mechanical torque input into an electrical output signal.

A torque transducer converts torque of various types such as reaction, dynamic or rotary into an electrical signal that can be measured.

TESNILE TESTING

Tensile tests are conducted on materials such as steel to deduce their ultimate tensile strength. The standardized tensile test specimen allows conclusions to be drawn about their characteristics and tensile properties.

Tensile testing is performed on a variety of materials such as Metals, Plastics, Elastomers, Paper, Composites, Rubber, Fabrics, Adhesives, Films, etc.

COMPRESSION TESTING / COMPRESSIVE FORCE TESTING

COMPRESSION FORCE TESTING

Compression testing is used to determine how a product or material will behave when it is compressed, squashed, crushed or flattened. This is done by measuring fundamental parameters that help to determine the specimen behavior under compressive load.

Compression testing machine is used to:

MASS/WEIGHT CALIBRATION

Correctly calibrated weights indicate precise results and will reduce the probability of any errors in weight measurement which otherwise could cause disastrous results. Calibration is in fact an investment that builds up the confidence for a user. Using non-calibrated equipment can lead to issues in production and quality.

Relationship between the mass and conventional mass of a weight in Calibration

The conventional mass value of a body is equal to the mass mc of a standard that balances this body under conventionally chosen conditions. The unit of the quantity "conventional mass" is the kilogram 

The conventionally chosen conditions are: 
tref = 20 C 0 = 1.2 kg m-3 c = 8 000 kg m-3 

The conventional mass has the same unit as mass, because its values are defined through the multiplication of a mass by a dimensionless quantity.
