The difference is measurement accuracy. Using 2-wire resistance temperature detector (RTD) sensing provides good accuracy (maybe), the accuracy of 3-wire sensing is better, and 4-wire sensing provides the best accuracy. In addition, there’s the option of using Wheatstone bridge topologies to improve the performance of 2- and 3-wire RDTs. This FAQ begins with a review […]

RTD probes come in 3-wire and transmitter models
Tel-Tru Manufacturing has introduced an advanced line of 3-wire industrial RTD assemblies and temperature transmitters. These probes are designed for the applications common to food and pharmaceutical processing, refineries, chemical plants, water and wastewater facilities, breweries, dairies, HVAC, and the OEMs serving them. The temperature transmitters provide 4-20 mA or HART outputs. Standard RTD assemblies […]
How can sensors ensure safety for extreme temperature requirements?
The medical device industry requires extreme high temperatures in autoclaves to disinfect reusable devices and tools. As we have been reminded of recently with announcement of COVID-19 antibiotics, medicines as well as bio-samples require low temperatures for preservation in storage and transportation. Both of these extremes require sensors to monitor and maintain the proper temperature […]
SMBD-RTD miniature bolt down RTD
Harold G. Schaevitz Industries LLC (HGSI) has expanded its sensor products by offering a new line of surface mounted, bolt down miniature RTD sensors for applications requiring a temperature sensor to be installed in confined spaces. Made in the USA, the SMBD-RTD Surface Mount Bolt Down RTD sensor delivers high-performance temperature measurements, reliably and consistently. […]
How can you get digital temperature data?
At Sensors Expo 2018, Mike Mays from Analog Devices explains the LTC2983, a temperature to bits IC. The IC is designed to be extremely easy to use part. Everything necessary to measure temperature is performed by the chip and its output is in direct degrees C. In the display, an “EMI (electromagnetic interference) Hairball from […]
Endress+Hauser announces self-calibrating RTD temperature sensor
Endress+Hauser has announced the iTHERM TrustSens hygienic RTD, the world’s first self-calibrating temperature sensor. TrustSens’ self-calibration process functions in situ and provides the necessary documentation to meet the conformance requirements for various regulatory agencies. Traditionally, calibration cycles for standard temperature sensors in critical service are every six to twelve months. This leaves the potential for […]
What’s the temperature of this thing?
Of course, there are many follow-up questions regarding where or when such as: on just the surface, in the center, on average, instantaneously, or steady state, to name a few. The standard temperature measurement technique that many people first encountered was the mercury (Hg) thermometer to determine if they had a 98.6° or higher temperature. […]
IC Simplifies Digital Temperature Measurements
At Sensors Expo 2016, Mike Mayes, a Design Engineering Section Leader from Linear Technology, demonstrates the capabilities of the LTC2983 temperature-to-bits converter that provides thermistor, thermocouple RTD and diode-based digital temperature measurements. For more information about the LTC2983, click here.
Measure Temperature While Meeting Hygienic Standards
Manufacturing processes in areas such as food, beverage and pharmaceutical industries need sensors for process monitoring and control. At the same time, these sensors must meet hygienic requirements from organizations such as the European Hygienic Engineering & Design Group (EHEDG) and 3-A Sanitary Standards Inc. (3-A SSI) as well as from regulatory agencies such as […]
