Omega Instrumentation

All over the industrial world, Omega instruments stand for precision, durability, and an almost unimaginable range of measurement technologies. It has built its reputation on one of the largest selections of sensors for temperature measurement—including thermocouples, RTDs, and thermistors designed to work in conditions from the lab to the manufacturing line. While Omega has become known for temperature measurement, it has long since evolved far beyond it, becoming in the process a common go-to resource for instrumentation in countless industrial settings that need accurate and dependable data to keep processes running smoothly and, above all, safely.

What stands out in the Omega catalog is the incredible breadth of what they offer. They make and sell pressure, flow, level, humidity, load, pH, and conductivity sensors with the same level of mastery they bring to temperature measurement. They offer advanced controllers, signal conditioners, data loggers, and calibration tools that let you string together an entire measurement system from one brand, with full assurance of compatibility and consistent quality.

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).
