It has exclusive setup to calibrate: Compression & Tensile steel testing machine CBR & Marshall Machines Proving rings Ovens Weighing balances Speedy moisture testers Asphalt & Concrete batching plants A wide area of material testing equipment as well as industrial instruments 4.0 COMPETITIVE ADVANTAGE The basic and most important requisite for quality improvement is process instrumentation because it is directly related to the quality of production. By maintaining process calibration we ensure the functionality of these instruments and their robust quality, providing a competitive advantage over the competition. 5.0 WHAT IS CALIBRATION? Calibration is a comparison between measurements - one of known magnitude or correctness made or set with one device and another measurement made in as similar way as possible with a second device. The device with the known or assigned correctness is called the standard. The second device is the unit under test, test instrument, or any of several other names for the device being calibrated. 6.0 FREQUENCY OF INSTRUMENT CALIBRATION Calibration can be called for: 1. A new instrument
2. When a specified time period is elapsed 3. When a specified usage (operating hours) has elapsed 4. When an instrument has a shock or vibration which potentially may have put it out of calibration 5. Sudden changes in weather 6. Whenever observations appear questionable In general use, calibration is often regarded as including the process of adjusting the output or indication on a measurement instrument to agree with value of the applied standard, within a specified accuracy. For example, a thermometer could be calibrated so the error of indication or the correction is determined, and adjusted (e.g. via calibration constants) so that it shows the true temperature in Celsius at specific points on the scale. This is the perception of the instrument s end-user. However, very few instruments can be adjusted to exactly match the standards they are compared to. For the vast majority of calibrations, the calibration process is actually the comparison of an unknown to a known and recording the results. 7. LIST OF CALIBRATION EQUIPMENT One of our big achievements is that we have successfully upgraded our equipment as per the needed for more precise results. Available Major Equipment for Calibration 1- Infrared Tachometer for RPM
With Digital Tachometer rotating objects, non-contact RPM (revolutions) and TOT can make measurements quickly and accurately. Through measurements of the laser device can measure and pasting reflective tape on the object. Wide Five-digit LCD display Built-in memory Max.Min. memory Technical Specifications Measuring range: 2 to 99,999 Accuracy: ± 0.05% ± 1d Max. rpm resolution: 0.1 rpm Measurement unit selection: None Memory: None Max. and min. Memory: Yes Screen freeze: None Average measurement: No Limit value alarm: None Carrying case: Yes Dimensions (HxWxD): 160mm x 60mm x 42mm Weight: 151g The device with the following: 9V battery and reflective tape 2- Compression Type Load Cell 2000 KN The HSC shear beam load cell has been developed for use in high capacity, compression type electronic weight and force measurement applications in industrial environments. The precise and rugged HSC load cell offers high resistance to side forces
and overload conditions. The HSC load cells are suitable for severe industrial conditions and they find application in high capacity vehicle scales, railway scales, tank weighing systems and Process weighing applications. With its steel alloy construction coated with corrosion-retardant paint as well as its strain gauge area welded with a stainless steel cover, HSC is protected to IP68 Standards meaning that they are fully immersible. Properties High capacity Heavy duty IP65 industrial protection Accessories J Box Connection Box 3- Digital Indicator for Load Cell The most basic member of the PWI series, the desktop-type PWI-D weight indicator offers all the major functions related to weight measurement and it is designed to be used in corporation with all sorts of electronic weighing devices. PWI-D offers such opportunities as compilation and storing of weight data by exporting them to a computer via its standard serial output. Properties; Plastic housing suitable for use on desktop 6-digit red LED weight display
Dust and humidity-proof membrane keyboard with tact keys Taring, zeroing, function and adjustment keys Zeroing within the entire measurement range Gain adjustment for load cell output Excitation and output voltage display for load cell RS232 serial output 4- Compression Type Load Cell 100 KN HT(1) type load cells are low profile. Work with principle of shear beam. They are available in 350 or 700 ohm. The flexure is made of a special alloy steel and it is ideal for low and middle capacity applications. HT(1) load cells were designed for both tension and compression applications. The sensing element is covered with special materials that isolate it from industrial environments. Stainless steel and nickel-plated HT(1) load cells are highly protected from external agents such as rain, dust, water that can make troubles for a good performance. They highly withstand to overloading and to the effects of off-axis loading.
Applications - Material testing machine - Lifting crane applications - Various weighing applications 5- Digital Indicator for Load Cell The most basic member of the PWI series, the desktop-type PWI-D weight indicator offers all the major functions related to weight measurement and it is designed to be used in corporation with all sorts of electronic weighing devices.
