What is an Air Handler?

Dwyer Instruments — Wed, 22 Mar 2023 14:09:52 +0000

Imagine you sit down at a restaurant on the outdoor patio, and as you’re waiting to order your food, you glance at the large HVAC system on top of the building across the street. Several questions cross your mind: Why do they need such a big system? And what goes into it? Today I want …

How to Choose a Proper Temperature Sensor

Michael Tischler — Wed, 15 May 2019 12:05:42 +0000

There are three main types of temperature sensors, and each one has its own strengths and weaknesses. Today we’ll be discussing the advantages/disadvantages of each RTD temperature sensors, thermistors, and thermocouples. A resistance temperature detector (RTD) is made from a sensing element that changes resistance with temperature. The majority of RTDs use a platinum temperature sensing …

RTD Temperature Sensors

Dwyer Instruments — Wed, 27 Jun 2018 12:32:41 +0000

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 …

Thermistor Temperature Sensors

Dwyer Instruments — Tue, 14 Nov 2017 16:00:47 +0000

Dwyer Instruments, Inc. manufactures and offers many temperature measuring products that use a thermistor as the sensing element. Thermistors are based on the principal that the electrical resistance of semiconductor materials is a function of the temperature. Thermistors work well over smaller temperature ranges with better accuracy than (RTD) but are very non-linear. They also generally offer …
