What is electrostatic discharge and how can it be prevented?

At one point or another we have all been exposed to some form of an electrostatic discharge (ESD) event, even something as simple as walking across a carpeted space, touching a door knob, and receiving an unexpected jolt. These types of events are very common in instrumentation applications. Today we will discuss what ESD is, the effects it has on instrumentation, and the steps that Dwyer Instruments has taken to prevent damage to sensors susceptible to these events.

Mystery Solved! Dwyer Solves the Wall Mount- Relative Humidity Error Problem

Wall mount humidity sensors for building automation system (BAS) applications are produced and sold by several different companies and have a reputation of poor accuracy despite specifications from suppliers. There is a rational reason why these instruments appear to read outside of their stated accuracy, which in turn causes users to be frustrated with the results.
