Causes of Measurement Errors in Thermocouple Thermometry
Reliable temperature measurement is dependent on several factors that, more or less, inexorably lead to measurement errors. In this article we discuss the common causes of measurement errors in thermocouple thermometry. Key causes of measurement errors in temperature measurement include: Thermal Shunting A temperature sensor conducts heat, which gives what is referred to as thermal…

Biomedical Sensor Specifications
The need for accurate medical diagnostic procedures places stringent requirements on the design and use of biomedical sensors. Depending on the intended application, the performance specifications of a biomedical sensor may be evaluated in vitro and in vivo to ensure that the measurement meets the design specifications. The following definitions are typically employed when describing…

Clinical Applications of NTC Thermistors
Thermistors are certainly the most used transducers for medical temperature measurements. Their properties facilitate clinically difficult measurements that include: hypothermia, transcutaneous measurements during cardiopulmonary bypass, testicular temperature measurements in reproductive medicine, continuous monitoring of preterm infants and personal heat strain monitoring in occupational medicine. Thermistors are also extensively used in a variety of clinical and…
