The SMD Engineering team includes experienced electronics engineers who can design fully integrated sensor solutions to provide precise and accurate outputs. RTD  |   } Output signals produced by temperature measurement sensors require conditioning to convert them to a form that can be used for further processing. Thermocouples The most popular transducer for measuring temperature is the thermocouple. }); PID Controllers  |   Over a range from 0 to 1000°C, RTDs have an accuracy of ±0.5 to 1°C. Ethernet is another form of differential high speed serial transmission that supports up to 1 GB/second transmission. However, the operating temperature range of thermistors is much narrower. /* ]]> */ Additionally, calibration curves indicate that the nonlinearity of thermocouples results in increased error over a wider temperature range. Sensors sometimes require voltage or current excitation, and signal conditioning/sensor interface products from Microstar Laboratories provide this excitation as required, along with processing the signal.
