How to calibrate pressure gauges - 20 things you should consider
Pressure gauges are very common instruments in the process industry. As any instruments, pressure gauges need to be calibrated at regular intervals to assure that are accurate. There are many things that need to be considered when calibrating pressure gauges. This white paper discusses 20 things you should consider when calibrating pressure gauges.
Data Integrity in Calibration Processes
As a concept, data integrity is by no means a new one, it has been around for several decades. Anyhow, in this article, we look at the data integrity more from the calibration process point of view, and focus mainly on the pharmaceutical and regulated industry. At first we take a look at the data integrity generally; what it is, why it is important and acute, what a breach could cause. Also, the ALCOA plus concept is briefly discussed.
Calibration in hazardous areas
This article discusses calibration in hazardous areas and what everyone needs to be aware of before entering into a hazardous area with calibration equipment. Other topics covered are flammable and combustible liquids, definition of a hazardous
area, the types of industries where hazardous areas are found, the different levels of hazardous zones, regulations, equipment classification and various
other practical and related issues.
Calibration uncertainty for non-mathematicians
This paper discusses the basics of uncertainty in measurement and calibration. The paper is designed for people who are not mathematicians or metrology experts, but rather to people who are planning and making the practical measurements and calibrations in industrial applications.
Pressure Units and Pressure Unit Conversion
There is a lot of different pressure units in use around the world and sometimes this can be very confusing and may cause dangerous misunderstandings.
In this article we will discuss the basics of different pressure units and different pressure unit families.
Also, an online pressure unit conversion tool is presented.
Temperature units and temperature unit conversion
In this paper we discuss temperature, temperature scales, temperature units and temperature unit conversions.
Read this white paper and find out:
- What is temperature?
- International temperature scales and units
- Conversions between temperature units
- Bonus: Free and easy to use temperature unit converter
Metrological Traceability in Calibration – Are you traceable?
What is metrological traceability in calibration and how you can be traceable?
This paper discusses what metrological traceability in calibration is and what you need to do in order to make your calibrations traceable.
In calibration, the metrological traceability is a fundamental consideration. If the calibrations you perform in your plant are not traceable, you don’t know if they are correct or not and therefore there is really no point in doing them.
Calibration Out of Tolerance (OoT) - What does it mean and what to do next?
Calibration Out of Tolerance – What does it mean and what to do next?
What is an OoT (Out of Tolerance) calibration, what does it mean and what you should do next if you run into an OoT situation? An out of tolerance calibration can have very dramatic effect, or no effect at all, depending on various parameters that are discussed in this paper.
The focus of this article is mainly for the world of process industry, but most of the principles are valid also elsewhere.
Calibrating WirelessHART transmitters
A modern transmitter is usually advertised as being smart and very accurate. Sometimes people may say that there is no need to calibrate smart transmitters.
The most common transmitter protocol today is the HART protocol. In this white paper, we will concentrate on WirelessHART transmitters.
Why calibrate
Calibration is an essential activity in the process industries. This white paper discusses how periodical calibrations of process instruments and test equipment influence plant performance, safety, maintenance, sustainability and product quality.
Calibrating smart instruments
So called “smart” instruments are ever more popular in the process industry. A modern process transmitter typically outperforms an older type of conventional transmitter in measurement accuracy and stability. However, they bring new challenges to the calibration and configuration processes.
How often should instruments be calibrated
Calibration is extremely important. If instruments at manufacturing plants drift out of their specification range, the consequences can be disastrous for the plant, resulting in costly production downtime, safety issues or possibly leading to batches of inferior quality goods. Still the time and resources for performing calibrations are often scarce.
The benefits of using a documenting calibrator
Documentation of the results is an essential element in every calibration. Documentation may be done manually using pen and paper, but it does not have to be! If you use documenting calibrator the documentation is done automatically.
A behind the scenes look at a calibration process change
Implementing an overhaul to a company's calibration process will not happen overnight. The biggest problems are usually caused by poor planning and inadequate resourcing.
The system implementation process can be broken down into six defined steps presented in this white paper.
New methods for calibrating loops
Instrument technicians are following practices that were set up many years ago and it is not uncommon to hear, "this is the way we have always done it." Measurement technology continues to improve and is becoming both more accurate and complex.
By reading this white paper you will learn how to analyze loop error and walk through various loop testing examples including wireless/fieldbus, multivariable and more.
When to calibrate in a workshop
In today's process industry, field instruments are often calibrated out in the field. Field calibration is often the best solution, but there are still various reasons why it is sometimes more convenient and effective to do calibration in a workshop.
This white paper discusses the most common reasons for workshop calibration.
