Dwyer Industrial Sensors
Dwyer industrial sensors provide reliable measurement of pressure, temperature, humidity, flow, air quality, level, and other conditions in your industrial process. They are known for their accuracy and consistent performance in HVAC, process automation, manufacturing, and environmental systems. These sensors withstand harsh environments and deliver repeatable readings that operators can depend on.
Dwyer designs housings, sensing elements, and internal electronics for rugged operation, even in dusty, humid, or high-vibration areas. Engineering expertise in robust sensor platforms means their products remain stable under heavy, continuous use. Dwyer’s instrumentation maintains accuracy over time, making it a go-to for utility plants, refineries, cleanrooms, and commercial buildings where reliability reduces downtime.
Dwyer offers sensors for differential pressure, static pressure, relative humidity, CO2 concentration, air velocity, liquid level, and more. Many of their sensors output analog signals or digital communication, simplifying integration to controllers, BAS systems, or SCADA. Field-selectable ranges and flexible sensor options make them compatible with many process requirements.

Analog and Digital Control Signals: The Basics
Digital Signals
Digital signals are represented in either a true or false. There is no gray area with digital signals. An example of this might be a light switch. A light switch is either on or off. Another example of this might be a motor that is running or not running. Digital signals can be generated with both AC and DC circuits with varying voltages, currents and resistance. Some practical examples of using digital signals in an industrial environment might be if a pump is running or not running or a whether a valve is open or closed.
Analog Signals
Analog signals convey information in the form of a range. A light switch might be on or off as a digital signal, but a dimmer switch would be an analog signal. It can be on or off, but it can also be somewhere in between. A practical example of using analog signals in an industrial environment would be if there is a need to measure the level of a tank; whether it's full, empty or somewhere in between. Analog signals can take many different forms with some of the more common being a 4 to 20 milliamp signal or a 0 to 5 or 0 to 10 volt signal.
Communication
Communication in a device can either be sent or received. Whether that data is sent or received depends on the type of information. Is there a need to monitor the status of something? If so, an input needs to be received about that information. Is there a need to control something? If so, an output needs to be sent about what needs to occur. Receiving inputs and setting outputs are both things that can be accomplished by using both digital and analog signal types. Therefore, the signals are referred to as analog outputs (AO), analog inputs (AI), digital inputs (DI) or digital outputs (DO).
