Quality Assurance Plan: |
Over the past thirty eight years EXCELLA ELECTRONICS has designed, developed, fabricated, inspected and supplied a large variety of instruments, tachogenerators, sensors and microprocessor based control system for industrial and scientific applications including power plants, steel plants, cement plants, defence & building automation. In the course of normal operation a resonable level of knowledge has been gained about the component quality, circuit/software reliability. Besides, this knowledge, experience has also been gained about sources of quality components
Apart from the knowledge so gained, specialised training is also imparted to our personnel in various fields to augment and update the knowledge base. The training is aimed at improving and understanding of the latest design techniques, quality standards and in enhancing the personnel community quality.
|
Procedure:
Design:
The design of the products is generally based on previous knowledge and experience.
In the course of the execution of a job a detail study of the customers application is made to decide the components which yield required quality. The system is designed by adopting proven and established techniques. |
|
Component Procurement & Inspection
Procurement Philosophy:
As a policy commercial grade components and circuit elements from LCSO or BIS or CDOT approved manufacturers are chosen. Whenever specifically demanded by the customer, only those components which company JSS is used. In either case the product of reputed and established component manufacturer is only chosen. Further certificates of compliance to the applicable specification is demanded directly from the manufacturer. However, for custom designed prodcuts of low volume consumption, it may not be always possible to procure components directly from sources with certificates.
Component Inspection:
In case where direct procurement is not possible, the purcahse of such components is made through reliable retail outlets and as a rule, essential paramatric tests are carried out at the incoming stage.
In case of components for which approvals do not exist, manufacturer with which the company has gained satisfactory experience are selected and then the components are procured. In such cases essential paramatric and any special test considered necessary in application are carried out at the incoming stage. |

• Programmable Safety Light Curtains |
|
Excella make programmable safety light curtains comprising of Transmitter and Receiver. This is solid state design, given guarantee of long life with minimum maintenance. The instrument has separate transmitters and receiver of operating modulated beam mode. This gives precise and reliable detection. |
|
Special Features : |
|
Invisible infrared beam transmitted to seperate reciver provides high reliability of detection |
|
Self checking circuitry monitors system failure. |
|
Provision for any number of channels to be enabled or disabled at the field. |
Advantage : |
|
Sleek and Attractive Unit |
|
Easy Mounting and Connecting Unit |
|
In Built power supply |
Use : |
|
High precise and reliable optical safety light curtain to operator's safety on machines like cutter, shears, brakes and presses etc. |
|

• Encoders
Incremental / Absolute Encoders : |
|
The Shaft Encoders are most precision measuring instruments i.e. Transducting angle speed & distance. Output is available in the form of pulses, incremental step by step in counter or processor. Direction can be obtained with the help of two trains of pulses in quadrature one index position pulse is available.

----------------------------------------------------------------------------------------------------------------------------------------------------- |
• Flexible Shaft Coupling
Spiral Coupling |
|
Features :
• Monolith Construction Backlash free - precision information transmission in both directions of motion without loss. This is possible due to the monolith construction of the body.
• Torsionally Flexible / Stiff - Producing constant velocity assuring smooth bearing loads.
• Takes misalignment - Leteral (typically 0.2mm) & Angular (Typically 5 degrees).
• Permits slight axial movement.
• Precise concentric integral set screw or collet / flange type clamping.
• Compact - space saving and lightweight with low interia.
• Suitable as diameter convertor.
• Import Substitute available. |
|
----------------------------------------------------------------------------------------------------------------------------------------------------- |
• Flock Printing Machine : |
|
Special Features :
This process gives velevet finish to the surface like wood, paper, Tin sheets, cloth etc. This machine with the strong electro static field gives uniform velvety touch to the products. Moreover, it is economical because there is no wastage of flock powder. The flock Powder lifts up the excess flock powder due to strong electro static influence. |
