The Digital Temperature Switch, Series TSW, combines the trusted, reliable TS family of temperature controls with an installation friendly weatherproof enclosure. Units come standard with an easy-to-read LED display that will indicate the current output status and temperature measurement. The TSW is ideal for applications such as: chillers, walk-in coolers, wood boilers, and brewing systems.

Calibration is the comparison and adjustment of a reading from an instrument in correlation with the reading of a higher accuracy piece of equipment. The overall goal of this process is to minimize measurement uncertainty and ensure the accuracy of an instrument.
In today’s industry, the number of device output signals continues to grow. Each signal is different; so how do you figure out which one is right for your application? The easiest way to hone-in on the correct signals for your application is to decide whether you want a digital communication signal or an analog signal.

The primary goal of HVAC technology is to determine the most effective approach to heat/cool the interior of commercial sized buildings. One of the most effective ways of achieving this goal is through the use of chilled beam systems. Continue reading “Chilled Beam Systems”
Dwyer Instruments, Inc. offers a wide variety of temperature sensors that use RTDs as the sensing element.
RTDs are based on the principal that the electrical resistance of the wire is a function of the temperature, with the resistance increasing as temperature increases. The resistance varies nearly linearly with temperature per the Callendar Van-Dusen equation. The wire used in RTDs as the sensing element is usually constructed of platinum, copper, or nickel. Platinum is the best material for this element, as it has the widest useful temperature range of these materials. It also has a very repeatable and linear temperature to resistance correlation.
