ELECTRONIC UNIVERSAL TESTING M/C :
Constructional : Venus make electronic Universal testing machine comprise of
a. Loading Unit
b. Measuring Control Panel
a.Loading Unit.: This is similar of standard loading unit of analogue type universal testing machine.
In addition to standard features of regular loading unit, a ROTARY ENCODER is attaches to the hydraulic ram to get accurate displacement of the ram.
b. Measuring Control Panel :
this includes,
1 : Highly Precision, sealed and very accurate pressure transducer mounted on the hydraulic pressure line of the loading unit
2: Highly stable ACQISITION system to convert Analogue output of pressure transducer into equivalent Digital Data.
3: Digital Single Processing Unit :
This is state of the art, MICROPROCESSOR based single processor which operates on Digital O/P single from Data ACQUISITION part and displays the break load etc.
4: Keyboard/ Display Panel :
This is ergonomically designed for best interaction between operated and the machine .
This incorporated sealed MEMBRANE type keyboard for data feeding & large display for load & displacement. Apart form display for load & Displacement.Apart a parallel printer port & RS232 serial communication port is also incorporated Through the printer port a Dot Matrix printer can be attached to get stress / strain curves as well as other test result. RS 232 port can be used for PC interface and hence to add variety of application software?s.
Accuracy and Calibration:
VENUS Universal testing machines are precisely controlled for accuracy and reliable calibration for accuracy and reliable Calibration during every stage of manufacture. The machines are calibrated in accordance with B.S 160: 1964 and grade 1 of I.S.: 1828-1991.
An accuracy of ? 1% is guaranteed form 20% of the load range selected from 20% of the load range selected to full load. Below 20% of the selected range the maximum permissible error 0.2% of the full load reading
