Circuit Grounding & Why it’s Important: Electrical Ground Rules Whitepaper

Why is circuit grounding important? This whitepaper is Part 1 of a three-part Grounding Electrical Equipment Best Practices series that looks at grounding and its role in protecting personnel, equipment, and ensuring the integrity of electrical signals. In this part, we will review circuit grounding and its importance to you, as well as the US…

Signal Isolation: What it is and Why it’s Important – Whitepaper

Why do we need signal isolation? Acromag is in the business of signal conditioning. We manufacture circuits that amplify, isolate, filter, and convert one signal form to another. Most of these circuits also provide electrical isolation. However, added isolation has a cost. Thus, sometimes customers either question their need for isolation or fail to recognize…

Strain Gauge Transmitters & Strain Measurement: Introduction White Paper

Introduction to Strain Gauge & Strain Measurement This paper discusses strain gauge and load cell input transmitters and strain and load measurement, as related to Acromag strain modules and transmitters in particular. However, the principles may be extended to other strain gauge or load cell instruments as well. Strain gauges change resistance in proportion to…

How to Get the Most for Your Money with Signal Conditioning: Whitepaper

This article reviews signal conditioning equipment features such as accuracy, adjustability, isolation, surge withstand capability, RFI/EMI protection, packaging, and repairability. Where possible, it also examines the relative importance of various features. Accuracy, Linearity, and Repeatability Accuracy, linearity, and repeatability specifications are described in many different ways. Accuracy specifications should include the combined effects of repeatability,…

Temperature Measurement Using RTDs White Paper

The Basics of Temperature Measurement Using RTDs Temperature reigns as the most often measured process parameter in industry. Most industrial applications require that a temperature be measured remotely, and that this signal be transmitted some distance. An industrial transmitter is commonly used to amplify, isolate, and convert the low-level sensor signal to a high level…

Temperature Measurement Using Thermocouples White Paper

The Basics of Temperature Measurement Using Thermocouples Choosing a temperature sensor for an application is not as simple as picking a thermocouple type with a compatible temperature range. You must give consideration to the sensor material type, the application temperature range, the relative sensitivity of the sensor, the limitations of its insulation material, and its…
