So you have an old tube-type transmitter as a backup. It ran perfectly when you last turned it on two years ago to substitute for your then-ailing solid-state main transmitter. Now you need it again.

“While most current transformers may look the same on the outside, it’s what’s inside that counts,” according to Meramec Instrument Transformer Co. April 29, 2016 “While most current transformers may ...

We needed to detect motion in a commercial, stepper motor driven system and subsequently initiate motion in a servomotor based system we developed. Because both systems simulate human respiratory ...

Sensing of current going to a load is a critical and often mandatory requirement in many designs. While there are many contact and non-contact ways to accomplish this sensing, such as using ...

Courtesy of www.MikeHolt.com. Based on the 2020 NEC. Article 450 of the National Electrical Code (NEC) opens by saying, “This article covers the installation of all transformers.” Then it lists eight ...

Like many hackers, [Matthias Wandel] has a penchant for measuring the world around him, and quantifying the goings-on in his home is a bit of a hobby. And so when it came time to sense the current ...

Common methods used to measure current. A new approach to current sensing: GaNSense technology. For any electrical control system, input signals of both voltage and current are critical for the system ...

Facing unprecedented lead times and skyrocketing costs, the transformer supply chain crisis threatens the backbone of the electric power industry, driving urgent calls for increased manufacturing ...

Instrument transformers provide reliable and accurate input for the protection, control and monitoring of power grid assets such as motor control centers, UPS systems, utility metering, low and medium ...
