Omega Pressure Switches
Omega pressure switches are built for dependability. They offer reliable, repeatable switching performance across most applications. Measurement devices in the commercial, industrial, and scientific arenas often need to make precise decisions based on pressure readings. That makes pressure switches a key part of a huge number of systems. For switching applications, pressure switches take pressure as their input. When the pressure reaches a certain threshold, the device changes its output state, most often going from a normally closed (NC) state to a normally open (NO) state or vice versa.
Omega provides its pressure switch line with comprehensive documentation, a wide range of customization options, and robust industry compatibility, allowing them to work effortlessly with all sorts of controllers, PLCs, pumps, motors, and safety circuits. Their standing in the industrial automation and engineering fields is built on decades of consistent product performance, technical know-how, and sensing technology innovations. Above all, they are known for offering what might be the trifecta of performance in pressure switches: reliable, configurable, and durable.
FAQs
What applications are Omega pressure switches used for?
Omega pressure switches are commonly used in industrial automation, HVAC systems, pumps, compressors, hydraulics, pneumatics, and process control environments where accurate pressure monitoring and safe system shutdown are required.
How accurate are Omega pressure switches compared to other brands?
Omega pressure switches are known for high repeatability, consistent set-point accuracy, and durable construction, often outperforming general-purpose switches in demanding industrial conditions.
Are Omega pressure switches compatible with hydraulic and pneumatic systems?
Yes, many Omega models are designed for both hydraulic and pneumatic service, with pressure ranges that support low-pressure air systems up to high-pressure fluid applications.
What materials are Omega pressure switches made from?
Depending on the model, Omega pressure switches may be constructed from stainless steel, brass, aluminum, or corrosion-resistant polymers to support harsh industrial or chemical environments.
How do I choose the right Omega pressure switch for my application?
Select your switch based on pressure range, media compatibility, electrical rating, set-point adjustability, connection type, and whether the application requires weatherproof or explosion-proof housing.
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).
