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.

OEM pressure sensors are accurate and repeatable when their sensing technology, materials, calibration and construction work together to deliver consistent pressure measurements over time and under real-world operating conditions.

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).

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. 

As a leader in pressure and temperature instrumentation, Ashcroft recommends customers apply ASME B40.100 guidance, which suggests choosing a gauge range that keeps normal operating pressure near the middle of the scale. This simple best practice supports accuracy, reliability and overall performance.

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.

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

Pressure gauge failure can be attributed to one or more of these eight reasons: mechanical vibration, pulsation, extreme temperature, pressure spikes, overpressure, corrosion, clogging, and mishandling/abuse.

Many industries use RTDs for measuring temperature, and the sensor in the majority of those devices are either Pt100 or Pt1000. These two temperature sensors have similar characteristics, but their difference in nominal resistance may determine which one you choose for your application.

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.

In many industrial processes, sudden pressure spikes—from water hammer, startup surges, pump cycling or valve events—can place measurement instruments under extreme stress. When a gauge cannot withstand these surges, the result is often permanent damage, unexpected downtime and avoidable maintenance costs.

Across industries like manufacturing, energy, HVAC, and process control, accurate pressure measurement is critical to maintaining safety, efficiency, and product quality. Over time, even high-quality pressure transducers can experience drift — a gradual deviation between actual and measured pressure caused by vibration, temperature changes, or normal wear.
 

When measuring pressure in challenging environments involving extreme temperatures, your instrument must perform accurately and reliably. Temperature exposure can come from many sources, including the process media and the ambient temperature surrounding the sensor. Each affects the transducer differently, but media temperature has the most direct impact because it acts on the sensing diaphragm and internal components. As media temperature rises or falls, it can distort readings, shorten sensor ...

Pressure gauges are instruments designed to deliver reliable and accurate readings in demanding applications. Yet, even the most durable gauges can lose accuracy or fail prematurely if they aren’t stored correctly. Many issues that appear as calibration drift or pointer error actually begin long before the gauge is installed—during storage and handling.

Pressure gauges can be found in virtually every industry. Depending on your application, these instruments play an important role in measuring the air, gas or liquid pressure in your system to keep it running safely and smoothly. However, for optimum efficiency, you will need to make sure the pressure range you choose for your gauge aligns with your application requirements and a few other factors. 

Selecting the correct electrical connection for a pressure transducer helps ensure your equipment continues to operate effectively, even when affected by vibration, moisture, dust, or temperature extremes that can compromise performance. From off-road equipment to process automation systems, choosing the wrong connector can lead to signal loss, premature failure, or even safety risks.

In industries where temperature extremes, vibration, or hazardous process environments are part of daily operations, accurate and reliable temperature measurement becomes a serious challenge. In these environments, operators need instruments that deliver accurate readings from a safe distance, reducing the need to approach hazardous areas.

Monitoring low-pressure processes comes with unique challenges. In industries ranging from food and beverage to wastewater treatment to liquefied natural gas (LNG) transfer, even modest changes in pressure can affect efficiency, product quality, or safety.
