Universal Testing Machine
-
A Universal Testing machine, also known as universal tester, materials testing machine, is used to test the tensile strength and compressive strength of materials. It is named after the fact that it can perform many standard tensile and compression tests on materials, components and structures. Along with these, there are many more capabilities of this testing machine. There are variety of terms in the industry that are used to refer to a UTM. Most common are “tensile tester”, “compression tester” and “bend tester”. An earlier name for a tensile testing machine is a Tensometer. It is used to play out the numerous tractable pressure and compressive quality of materials or parts.

Manufacturers of electrical or electronic products are required by law to carry out an electrical safety test before placing them on the market. This final test takes place at the end of the manufacturing process and is therefore also referred to as an EOL test (end-of-line). Depending on the prescribed standard and directive, the following parameters are tested:- Leakage current and discharge current- Insulation resistance or the insulation strenth- Dielectric strength or electric strength- Correct installation of the protective conductor (ground continuity and ground bond test)- Faultless functioning of the product under the conditions defined for intended use (function or run test

Circuit Breaker Test Equipment
-
DV Power has released a new generation of circuit breaker test equipment for condition assessment of medium and high voltage circuit breakers.Field-portable instruments with standalone or PC controlled functionality, allow performing various tests during circuit breaker manufacturing, commissioning and maintenance stages.Applications supported by the DV Power test equipment include measurements of:Contact resistanceDRM (dynamic resistance measurement)Coil resistance and coil current (IEC 62271-100)Mechanism charging time (IEC 62271-100)Minimum trip voltage (IEC 56, ANSI C37.09)Undervoltage release (IEC 60694)The timing of a circuit breaker’s main, auxiliary and pre-insertion contactsSynchronization between the contactsMotion and velocity“First trip” testThe essential part of a circuit breaker condition assessment is the ability to compare the latest test results with the previous testing. Accordingly, our instruments store measured values and compare them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements. In order to obtain an accurate comparison, the tests need to be performed using identical test parameters. Consequently, any deviation and change in the test results may indicate the circuit breaker condition deterioration. Even more, to overcome this issue, DV-Win enables test plans and graph overlay features.Finally, as a final result of a circuit breaker maintenance process, the DV-Win provides analytical tools and customized report creations.

Automated System for Identification and Control of Pharmaceutical Codes
-
The automated system for identifying pharmaceutical codes includes two scanners of the pharmaceutical code, two sensors for the presence of an object and a data processing unit (BOD). When the box or instructions are passed under the object presence sensors, the farm code is read by the corresponding scanner and the results are transmitted to the computer via the Ethernet interface. The BOD verifies the correctness of the read out farm code by comparing this code with the reference farm code set at the beginning of the system operation. If the farm code has not been read or does not match the standard, the packaging machine stops and the type of error is displayed on the indicators.
