Omega Pressure Gauges
Precision, durability, and versatility define Omega pressure gauges, making them suitable for many applications across industry, commerce, and lab environments. The gauges are designed to provide not only accurate but also stable pressure readings. Their operation is such that once you set a gauge onto a system, it almost immediately tells you whether that system is behaving in a safe or normal manner.
What is also quite common across many different types of Omega pressure gauges is that they are made out of materials eschewing what the industry has deemed "coarse paths to failure." Successive layers of enclosures, housing, and internal components protect the gauge from a harsh operating environment (lots of vibration, a broad range of temperatures, even exposure to chemical vapors or moisture). The gauges you see in chemical plants, for instance, are a type of Omega pressure gauge.
FAQs
What are Omega pressure gauges used for?
Omega pressure gauges measure system pressure in pumps, compressors, hydraulic systems, pipelines, HVAC units, and industrial process equipment.
What types of pressure gauges does Omega offer?
Omega provides stainless-steel gauges, dry mechanical gauges, glycerin-filled gauges, and specialty low-pressure and high-accuracy models.
Why choose a glycerin-filled Omega gauge?
Glycerin-filled gauges reduce vibration and pulsation, improving needle stability and extending gauge life in dynamic pressure systems.
Are Omega pressure gauges suitable for corrosive or chemical environments?
Many models use stainless steel and corrosion-resistant materials designed specifically for aggressive fluids and harsh industrial conditions.
Do Omega pressure gauges work for low-pressure applications?
Yes, Omega offers diaphragm and low-pressure models ideal for air, gas, filtration, and draft monitoring.
Instrumentation: Elements & Transmitters
2 pieces of hardware used in modern day instrumentation: measuring elements and transmitters.
Measuring Elements
Measuring elements are the part of the device that performs the measurement. For example, the measuring element of a pressure transducer is the part that is actually lowered into a tank that will take a pressure measurement. The measuring element of a flow meter is the part that actually measures the flow and an RTD or thermocouple takes the temperature measurement.
Transmitters
Transmitters collect information from measuring elements and sends the information to where it is needed. The transmitter interfaces with the measuring element and interprets the information. It then sends that information to a PLC, RTU or some other type of control unit. In many cases, the transmitter has the ability to communicate the information via multiple communication protocols. This may be necessary when the measuring element does not send the same type of signal that is needed by the controller. For example, it may be necessary to convert a temperature reading from a thermocouple to a 420 milliamp signal that can be received by a local PLC.
