In aerospace applications, pressure transducers and switches play critical roles in monitoring many systems throughout the aircraft—from hydraulics and electromechanical systems to avionics. Braking, propulsion, wing flap control, cabin pressure and countless other functions rely on pressure transducers and switches to ensure that the process is happening correctly. Accuracy is critical.
Because these devices are constantly subjected to extreme vibration, frequent ambient temperature changes...

Investing in calibration automation software (also referred to as calibration management software) is a major undertaking for any laboratory. While many metrologists and lab managers see the potential benefits, there’s a steep learning curve and a litany of decisions to research along the way. Beyond the financial cost, cal labs must consider the investment of staff time in learning to use and configure the software, and questions about how best to integrate automation software into their...

A technician calibrating an analog pressure gauge with a Fluke 2700G reference gauge
Analog pressure gauges are still widely used because they are relatively inexpensive and can do the job for many applications. Digital pressure gauges may be more expensive than an equivalent analog gauge because they are generally more accurate due to the nature of the display and the technology behind it.
There is a fair amount of overlap in applications where you can use a digital or analog gauge...

A rotameter, also called variable area flowmeter, is inherently a volumetric flow measurement device. The word origin is rota(tion) + messer/measure/meter. The scale can be in mass flow units if the volume flow rate is multiplied by a specified density, and in dimension units (mm) or percent.
An indicator floats at a steady value when the forces on it are equal. The main forces are the weight of the float (downward) and the drag force of the fluid (upward). Other forces are the difference in...

One of the most frequently asked questions I hear from customers is “what is the best type of calibration standard for analog pressure gauge calibration or digital pressure gauge calibration?” My initial answer is always the same…”it depends.”
The only way to fully answer that question is to dig deeper into the details of your specific workload. There are a lot of variables that effect the pressure calibration standard you choose. The following is a list of key questions that can guide you to...

The Fluke 5790B AC Measurement Standard is a multi-purpose ac measurement standard that combines the accuracy you’d expect from a thermal transfer standard with the ease of use of a digital multimeter.
In this article, electrical calibration expert Marty Kidd explains why someone needs this type of product. He also explains why owners of an old Fluke 5790A should consider moving up to a new 5790B.
Why does someone need a 5790B?
They need a 5790B measurement standard if they have some...

Technicians calibrating an infrared thermometer temperature gun
Because of the COVID-19 pandemic, there is a lot of interest in measuring human body temperature. I’m sure you’ve seen articles or you had your own temperature measured as you entered a public place like a store or medical building. Most of the interest in measuring human body temperature is in the area of non-contact or infrared (IR) temperature measurement. Infrared measurements are ideal for this fever screening because making...
