Capacitance Polymer Humidity Sensors
Humidity sensors are one of the most common types of sensors used for HVAC equipment and building management systems. With proper humidity monitoring, energy efficiency of a building can be improved. By using environmental conditions in conjunction with an economizer to reduce the building load, cool outside air is used to cool the indoor space of a building. Dampers, humidity sensors, and temperature sensors are used to verify optimal outdoor conditions for maximizing energy cost savings. Continue reading “Capacitance Polymer Humidity Sensors”
Analog vs. Digital Device Signals
In today’s industry, the number of device output signals continues to grow. Each signal is different; so how do you figure out which one is right for your application? The easiest way to hone-in on the correct signals for your application is to decide whether you want a digital communication signal or an analog signal. Continue reading “Analog vs. Digital Device Signals”
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. Continue reading “What is electrostatic discharge and how can it be prevented?”
