In The basics of 4-20mA current loop transmitters, I discussed the basics of 4-20 mA transmitters, a popular communication method to and from field elements in factory automation and other industrial ...

There are essentially four different types of pressure measurement transmitters. Absolute pressure transmitters measure against a vacuum, meaning that if no pressure is applied, the reading would ...

Recent advances in high-speed data converters now digitize or generate signals directly at radio frequencies up to several gigahertz, replacing traditional radio-frequency (RF) components like mixers, ...

Two-wire transmitter technology came about from an agreement among various instrument suppliers in the 1950s to standardize on 4-20 mA current loops as a means of sending a flow, temperature, pressure ...

At least once every year we take a look at new features in transmitters. LPFM is in our industry news quite a bit as of late, so we’ll look at some equipment that could be used for LPFM as well: small ...

Established transmitter suppliers have introduced several new product lines this year, with most of the action coming in FM at lower power levels. What other trends are notable in transmitters? We ...
