Sensor Description:

The DT026 sensor is a Thermocouple type J Temperature sensor with a sensing range of 0 - 750 °C. It is extremely accurate, and has a maximum error of 2% over entire range. The DT026 consists of a Fourier Systems' egg-shaped sensor case and a 20-cm Ther-mocouple wire.

How it works:

A Thermocouple consists of two long wires made of different metals being connected at one end and being very close (but not connected) at the other end. When the connected end of the thermocouple is placed into an area of higher temperature than the other end, a voltage builds up between the wires at the other end. This is the principle, which the DT026 works by. The DT026 is equipped with an additional internal temperature sensor designed to compensate for room temperature. Finally, the voltage received after correcting this offset is amplified and adjusted to a range of 0-5 Volts, accepted by the analog-digital converter. The proper result is than recorded into the Logger's memory.

Calibration:

The DT026 is fully calibrated, and does not require further calibration. However, there might be degradation in the accuracy over the time. For further calibration the DT026 is equipped with a simple calibration mechanism. In order to calibrate the sensor you need a reference temperature. This temperature must be higher than 0°c, and must remain steady during calibration. Insert the end of the wire into the water, and then start recording data. While recording data, insert a flat screwdriver into the calibration hole on the back of the sensor case and slowly turn the screw inside until the measured value matches exactly the reference value. The sensor is now calibrated.

What is it used for:

The DT026 sensor is mainly used for measurements of high temperatures, monitoring chemical processes occurring at high temperatures, or simply monitoring ovens. The high accuracy and reliability of the DT026 makes it an excellent tool for education and industrial use as well.
