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 …

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 …
