The Basics of Digital Multimeters

By Jim Gregorec, Ideal Industries
A digital multimeter (DMM) may look complicated and intimidating at first glance, but once you understand the display, dial, and port panel, you'll have a better grasp of DMM basics. Click here to read full article...

Why Use Temperature Transmitters Instead of Direct Wiring?

When making temperature measurements, two ways have traditionally been employed to get process readings back to a monitoring and control system. One method is to utilize sensor extension wires to carry the low-level signals (ohm or mV) generated by field-mounted RTD or thermocouple sensors. Another is to install temperature transmitters at or near the measurement point. The transmitter amplifies and conditions the sensor signal, and transmits it over a twisted wire pair back to the control room. Read full article.

10 Tips for Choosing Temperature Transmitters

While there are many practical and economic advantages to using temperature transmitters, the most basic are to ensure measurement integrity and to convert a temperature sensor’s low-level (ohm or mV) signal to a standard 4-20mA current signal that can be readily accepted by a monitoring and control system, such as a DCS or PLC. Advancing technology has made the use of temperature transmitters affordable, even in cost-sensitive applications. Here are few things to consider when choosing one. Read full article.
