Dwyer vs COVID-19 | Monitoring Air Flow & Pressure in Hospitals

Dwyer is committed to aiding in the fight against COVID-19. We have several products that are used in hospitals and the production of ventilators. Ventilators are used to aid COVID-19 patients who have low oxygen levels, support their breathing, and bring oxygen levels to a safe range.

Isolation Room Application

In addition, isolation rooms need to remain at specific pressures and air cycles, so as to not risk exposure of airborne contagions to other patients or healthcare professionals during treatment. Today we’ll be discussing some of the products that Dwyer manufactures that are used in these applications. Continue reading “Dwyer vs COVID-19 | Monitoring Air Flow & Pressure in Hospitals”

Pressure Transducers vs. Pressure Transmitters

What are the differences between pressure transducers and pressure transmitters?

Many readers have likely heard the terms transducer and transmitter used interchangeably without much confusion. When searching the internet for either term, search engines provide nearly identical results. Are there any differences? The short answer is “yes”.  Continue reading “Pressure Transducers vs. Pressure Transmitters”

Gas Mass Measurement

Energy costs are rising around the world. In the United States, the cost of electricity, natural gas, and coal are all expected to increase in 2020.[1] As oil prices increase, energy costs are rising in Britain, and in Australia, the cost of electricity has skyrocketed.[2] It will become increasingly necessary to manage costs by maintaining efficient operation of energy systems as energy prices continue to rise.

Steam is a common byproduct of energy generation in boiler systems. When energy is generated in a boiler system, heat energy is transferred to water, which generates steam used for heating. Measuring the steam produced by a boiler is the most logical way to measure boiler output, but it is extremely difficult to measure steam output accurately.[3] In a world where energy costs are only expected to increase, it is imperative that boiler output be measured accurately in order to conserve both money and energy.

What Are 3-Way Ball Valves?

3-Way NPT Stainless Steel Ball Valve, Series WE31

Dwyer Instruments offers a diverse line of 3-way ball valves with a variety of body materials such as brass, stainless steel, and plastic. We also have a variety of end connections to choose from, including: NPT (National Pipe Tapered threads), tri-clamp, flanged, or socket.

What is a 3-way ball valve?
A 3-way ball valve, also known as a multi-port valve, has 3 ports or openings, where one port is common to the other two.  This third port offers the fluid an alternate path of travel, which permits the valve to have one inlet and two outlets, or two inlets and one outlet. They also provide simple and economical flow shut-off and direction control in one valve body. Continue reading “What Are 3-Way Ball Valves?”

How to Set Up and Record with a SCD and Mini-Node™ Signal Converter

The DIN Rail Temperature/Process Controller, Series SCD, offers multiple PID loops in a compact size. Each SCD-1000 master controller can be combined with up to seven SCD-2000 slave controllers without any wires. Each controller has one universal input, one relay output, and one user selected output.

The Series SCD can be used with a Mini-Node™ Signal Converter for applications such as: oven, boiler, or chiller control; packaging equipment; environmental chambers; medical equipment; or food service equipment. The Mini-Node™ converter, Model MN-1, is a low cost device that converts half duplex RS-485 serial communications signals into a signal that can be read by any computer with a USB port.

Wiring up the MN-1 to an SCD controller can be accomplished in just a few steps, and the set up software is simple to use. Continue reading “How to Set Up and Record with a SCD and Mini-Node™ Signal Converter”
