The Importance of Calibration for Manufacturing

In scientific labs, instruments are calibrated to help maintain their performance and accuracy. Hence, it’s a process that is an integral part of any instrument. The manufacturer has to keep in mind the calibration factor and design the product accordingly. This article gives a basic understanding of the level of importance calibration holds to the manufacturer of the device. Calibration and its Relevance to Manufacturing Calibration is the process of finding the relationship between two unknown readings. Broadly speaking, it is a process of comparison. The readings may be shown by an instrument such as a voltmeter. Every value that … Continue reading

How to Control Use of a Group Lockout Box for Isolations

The importance of effective and total energy isolation cannot be over-emphasised at every possible instance, given the heavy damage accidental re-energisation of equipment under maintenance continues to cause. Be it due to the lack of awareness, the absence of clear-cut processes and guidelines, or poor implementation of Lockout Tagout processes, it has been observed that de-energisation is a key contender for close attention, especially when working with automated and integrated processing systems. Energy Isolation in Complex Systems It is but natural for complex and integrated systems comprising a series of heavy machinery to be powered by multiple energy sources – … Continue reading

Thermal Imaging & Infrared Cameras

There is a wide variety of uses for Thermal imaging cameras or infrared cameras depending on the information required for a particular task. It is important to understand the differences between these types of camera’s and what they are capable of before investing in equipment which may not be suitable in the application they are required for. Infrared cameras differ from thermal imaging cameras as they use short wavelength infrared light to illuminate the required location or point of interest and as fragments of the infrared energy gets reflected back into the camera it is then turned into an image … Continue reading


Advantages of Thermal Imaging in Preventative Maintenance

Reactive maintenance and repair costs due to equipment failure can be quite aggravating and costly for companies. Thermal imaging can play an important role in enabling maintenance professionals to monitor equipment performance and therefore schedule planned maintenance while also extending the lifespan of essential machinery and equipment. What is Thermal Imaging? Heat generation is often an early indication of equipment failure or damage, making it vital to monitor. Thermal imaging uses infrared-sensitive cameras to inspect the infrared energy emitted by electrical equipment, machinery or buildings and produce thermal or heat pictures to help maintenance technicians locate faults commonly related to … Continue reading


What is a PAT Tester?

What is a PAT Tester? PAT tester is short for Portable Appliance Tester. A PAT Tester is an electrical safety testing device that tests any appliance in which a plug top is fitted. The idea behind the PAT test is to ensure that the electrical safety parameters i.e earth continuity/insulation resistance that were embedded by the product manufacturer have not been compromised while the equipment is in service.


10 Reasons To Get PAT Testing Training

Electric Arc Protection – Protection through Layers

Electrical hazards at the workplace range from mild electric shocks and burns to more severe injuries and health complications that result from brief yet powerful arc flashes. Electric arc flashes and blasts are capable of causing severe burns. The extreme heat and acoustic waves can damage vision, hearing or even trigger concussion and memory loss. The impact of such blasts can prove fatal, especially when workers are thrown off elevated work platforms, scaffoldings or ladders. Employers can ensure safety of workers, who are prone to electric arc risks as a part of the their daily jobs, by opting for suitable … Continue reading

The Importance of Applying a Tag When Locking Out an Energy Source

OSHA standards related to control of hazardous energy require companies to formulate effective energy isolation processes that best suit their workplace, after careful consideration of the different energy sources being used in the manufacturing facility. When Locking Out an Energy Source each type of energy source should be locked out by applying the right lockout device and tagged appropriately to visually warn people who share or use the same work area. While ball, gate and butterfly valves serve to lockout pneumatic and hydraulic systems, electrical energy is isolated by using suitable Miniature Circuit Breaker (MCB) lockout toggles or pin-in/pin-out devices … Continue reading


Fluke Process Calibration – Loop Calibration and Maintenance

Calibration is generally done for instruments that are used for obtaining accurate results. The outcome of a measurement is referenced with some standard values and checked for precision. Many manufacturers offer to pre-calibrate instruments prior to sale. The calibration documents are given with the device for the safety of the customer and for service purposes. Calibration enables both the users and businesses to be assured in the results that they record and control. Calibration is starting to diminish within domestic confinements and has taken over the field of manufacturing. As a result, devices in the market have become highly reliable, since the possibility … Continue reading


What is calibration?

Calibration is a comparison between two measurements – one of known level or correctness with one device (known as the standard) and another measurement made in as similar a way as possible with a second device (known as the unit under test).
