Strain and Strain Measurement an Introduction White Paper

Introduction to Strain & Strain Measurement This paper covers the topic of strain gauge & load cell input transmitters and strain and load measurement as related to Acromag strain modules and transmitters, but may be extended to other strain gauge or load cell instruments.

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…

Why You Need USB Isolation for Industrial IO White Paper

USB Isolation and Industrial I/O Isolation is achieved by removing any direct electrical connection between two devices or portions of a circuit, but having them work as if they were electrically connected. Isolation is generally rated by how high a low current AC voltage can be set before there is arcing across the isolation barrier….

WHITEPAPER: Introduction to the Two-Wire Transmitter and the 4-20mA Current Loop

In two-wire 4-20mA control loops, we use 2-wire transmitters to convert various process signals representing flow, speed, position, level, temperature, pressure, strain, pH, etc., to 4-20mA DC for the purpose of transmitting the signal over some distance with little or no loss of signal. This paper reviews the operation of this transmission standard and its…
