A test gauge is a high-accuracy pressure measurement instrument serving as a reference to verify the performance of other pressure devices, such as working gauges, pressure switches or transmitters. Over time, pressure gauges and sensors in process and industrial systems can drift due to wear, temperature changes, vibration or process conditions. Having a reliable reference helps ensure that your pressure reading can be trusted.

If you work in an industry that involves high-heat processes, such as oil and gas and petrochemical applications, you know the challenge of keeping your pressure and temperature measurement instruments working effectively. These instruments are put to the test daily with exposure to extreme temperatures, abrasive chemicals and other elements that may not be compatible with the wetted components (parts that are in contact with the process).

The Naftosense ethanol leak detection system is designed specifically for alcohol-based products. It’s immune to water and can detect ethanol and other alcohols at concentrations as low as 20 percent, even when dissolved in groundwater.

A differential pressure (DP) gauge is used to measure flow by converting the pressure drop created by a flow restriction into a readable flow rate based on established fluid dynamics principles. In many industrial applications, engineers need a reliable way to monitor liquid or gas flow but may not require the complexity or cost of an electronic flow meter. In these cases, a DP gauge provides a simple, mechanical solution for flow indication.

Material compatibility in pressure instrument selection matters because even well intended material upgrades can introduce hidden risks when components interact in real process environments. 

Resistance temperature detectors (RTDs) are passive components whose resistance changes with a change in temperature. This can be measured very accurately, enabling an RTD to translate temperature into a stable electrical signal, even in demanding industrial environments.

The National Institute of Standards and Technology (NIST) is the U.S. National Metrology Institute responsible for maintaining primary measurement standards. ISO/IEC 17025 is the internationally recognized standard for testing and calibration laboratories. Both organizations provide widely recognized calibration frameworks used to ensure accurate, reliable measurement results across many industries.

Most pressure gauges around the world have either an NPT or G (metric) connection for insertion into processes. It is useful to know their differences – and also how to recognize which type is in use – without having to remove the entire assembly.

Thermocouples are among the most popular temperature measurement instruments in industrial applications because of their versatility and ease of use. However, measurement errors can occur. This article discusses the six most common causes of thermocouple errors.

Pressure measurement is all about PSI. That’s because pounds per square inch (PSI) is the most common unit for measuring pressure in the U.S. It’s important to understand what PSI means and how it is used, as pressure measurement is an important part of life in the 21st century.

Almost everyone uses the terms pressure sensor, pressure transducer, and pressure transmitter interchangeably, and that’s okay!

The magnetic level indicator working principle is used in level instrumentation. The interaction between the float magnets inside the chamber and magnetic flags outside the chamber provides continuous level information. This type of level indicator doesn’t require power, making it ideal for a variety of applications across industries.

Are your gauges installed properly? WIKA’s industry experts know that all too often this isn’t the case. Improperly installed gauges can lead to premature gauge failure and prevent you from troubleshooting issues with equipment or processes. Don’t let this happen at your plant. Use these six tips for proper gauge installation.

Motion architecture may look fine on paper until the cycle rate increases, the available space shrinks, and the “simple” pick-and-place head becomes far more complicated than expected.

Differential pressure transmitters are designed to measure pressure before and after the fluid encounters an interruption, such as a filter or pump. However, this pressure instrument can also be used to measure liquid levels. 

By measuring differential pressure, users can easily and accurately monitor filter conditions, liquid levels in closed tanks, liquid flow rates inside a pipe, and even the output torque of hydraulic motors.

When installing thermowells in a pipeline, a user must first answer several questions regarding their location, quantity, stem length, distance from each another, and effects on the process media.

Many factors go into the decision of which industrial pressure gauge to purchase. Asking the “STAMPED” questions regarding Size, Temperature, Application, Media, Pressure, “Ends,” and Delivery time will help buyers determine which gauges are right for their specific situation.

One of the most challenging elements to motion control is the integration of robots.  However, the benefits that can be achieved through this type of integration cannot be understated.

Heating, ventilation and air conditioning (HVAC) systems are the backbone of building comfort and safety. Because these systems operate continuously and consume significant energy, even small inefficiencies can drive up operating costs.

Learn how proper sizing, flow rates, and system parameters impact coalescing performance in three-stage liquid filtration. Improve efficiency and ensure accurate separation.

In many industrial and pneumatic systems, pressure control is essential. But not all pressure regulators are created equal. Two of the most commonly used devices—pressure regulators and back pressure regulators—perform very different roles. Choosing the right one depends on where you need to control pressure in your system.

If you've ever found yourself asking "What exactly is a linear servo motor positioner versus a linear servo motor actuator versus a linear servo motor stage?" you're not alone. Let’s break this down clearly and simply.
