Dwyer Pressure Gauges
Dwyer pressure gauges are known for their reliable performance, sturdy construction, and clear readability. They have become some of the most trusted instruments in industrial, commercial, and HVAC applications. When a technician in any of these fields uses a Dwyer pressure gauge, they do so confident in the knowledge that the instrument will provide a consistent, accurate reading for the operational pressure of any given system.
Dwyer makes both mechanical and electronic pressure gauges, with the majority of their models falling under the former category. These standards of the industrial gauge world are well-regarded for their affordability and the durability of their design. When using their standard bourdon-tube mechanical gauges for basic pressure monitoring tasks in any kind of system with a nominal pressure rating, operable under the conditions of a basic industrial environment, one can expect unfailing accuracy and clear readability even at a distance.
FAQs
What are Dwyer pressure gauges used for?
They monitor system pressure in pumps, compressors, filtration systems, HVAC units, pipelines, and industrial machinery.
What types of pressure gauges does Dwyer offer?
Dwyer offers bourdon tube gauges, glycerin-filled gauges, stainless-steel process gauges, diaphragm gauges, and specialty low-pressure models.
Why choose a glycerin-filled Dwyer gauge?
Glycerin-filled gauges absorb vibration and pulsation, helping stabilize the needle and extend gauge life in dynamic systems.
Do Dwyer pressure gauges work for low-pressure applications?
Yes, Dwyer manufactures diaphragm gauges and low-pressure models ideal for air, gas, draft, and filtration monitoring.
Do Dwyer pressure gauges integrate with control systems?
Mechanical gauges do not output a signal, but many operators pair them with transmitters or switch gauges for automation integration.
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.
