While the end of the calendar year is busy for many Sales Departments focused on hitting their quotas, the Engineers at Dwyer Instruments, Inc. put in long hours each December to release the latest innovations for the HVAC market. In 2017, Dwyer released three award winning products (the PredictAir® Software App for the Smart® Air Hood Balancing Instrument, the Series AVUL Air Velocity Transmitter, and the 490A-HKIT Hydronic Balancing Manometer Kit) for the AHR Expo. For next week’s 2018 edition of AHR, the Dwyer team raised the bar another level with a slew of new product innovations. Continue reading “Check Us Out at AHR 2018!!!”
There’s No Time for Downtime | Insertion Electromagnetic Flow Transmitter
With the release of the Insertion Electromagnetic Flow Transmitter, Dwyer Instruments, Inc. provides performance, accuracy, and reliability with same day field configurability.
Previously, insertion flow transmitters on the market did not offer much flexibility to configure products in the field. Dwyer addressed these concerns, delivering a solution with their new unit. Continue reading “There’s No Time for Downtime | Insertion Electromagnetic Flow Transmitter”
What is Deadband? Switch Actuation and Deactuation
Dwyer Instruments offers many electrical switch products that make or break a contact based on sensing a parameter such as pressure, temperature, level, and so on.
Most switches are single pole double throw, often referred to as SPDT. This type of switch has one normally open contact and one normally closed contact. Switches can also be double pole double throw, or DPDT, that have two normally open and two normally closed contacts. Single pole single throw switches with just one contact are also available and are specified to be either normally open or normally closed.

Variable Area Flowmeters
Dwyer Instruments, Inc. offers many flow measuring products including our very popular variable area flowmeters, often called rotameters. Dwyer manufactures variable area flowmeters in polycarbonate, poylsufone, fluoropolymer, acrylic, glass, and metal. Please see the Dwyer website for more details on these products.
Infrared Thermometers
Dwyer offers several temperature measuring products that use infrared sensors as the sensing element.
Infrared Thermometers infer the temperature of an object by measuring the infrared thermal radiation emitted from the object. Objects at thermal equilibrium must balance the energy that is entering the object with the energy that is leaving the object. Often, the energy leaving the object is emitted as electromagnetic radiation. Continue reading “Infrared Thermometers”
