White Paper: Introduction to Strain and Strain Measurement

Strain Gauge & Load Cell Input Transmitters 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. Strain gauges change resistance in proportion to applied forces that…

WHITEPAPER: The Basics of Temperature Measurement Part 2: Using RTDs

The Basics of Temperature Measurement Part 2: 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…

WHITEPAPER: The Basics of Temperature Measurement Part 1: Using Thermocouples

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…

WHITEPAPER: Minimizing Measurement Error When Making Thermocouple to Transmitter Connections

HOW TO PREVENT TEMPERATURE MEASUREMENT ERRORS This white paper will benefit you in 3 ways: It will give you a keen understanding of the three basic laws of thermocouples: Homogeneous materials, Intermediate Metals, and Successive/Intermediate Temperatures. It is helpful in weeding out potential sources of error in a thermocouple measurement system. It’s also valuable in…

WHITEPAPER: Why You Need USB Isolation

USB Isolation and Industrial I/O The USB port has become the most popular method for connecting virtually anything to a computer such as simple flash drives to complex industrial I/O equipment. Most computers built in the last 5 to 10 years have at least 1 USB port with newer computers having upwards of 6 or…

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…

WHITEPAPER: Electrical Ground Rules Part 3

Best Practices for Grounding Your Electrical Equipment This Electrical Ground Rules paper is Part 3 of a three-part series that takes a look at grounding and its role in protecting personnel and equipment, and ensuring the integrity of electrical signals. Consideration of ground can be very complex and application specific. But in many of these…
