Temperature & Humidity Sensors Dubai UAE

Temperature Sensors is a resistance Thermometers are used widely from -200 to +850°C in different process. Especially at low temperature, resistance thermometers are prefered since their accuracy is much better than thermocouples. Up to 400°C standard types and between 400-850°C special types are used. The maximum immersion length of the resistance thermometers should be determined by considering the measurement errors that may be caused by heat transfer occurring along the protecting tube and R/T element. The fluid speed where the resistance thermometer is immersed is a factor affecting the measurement sensitivity. In general, R/T should be perpendicular to the flow direction. Copper conductive cables are used between resistance thermometer head and the instruments. Up to 10 meters, 2×1.5 mm copper cable, up to 150 meters 3×1.5 mm copper cables, after 150 meters 4×1.5 mm coppercable are used.

Straight Thermocouple with metal ceramic protecting tubes are widely used in a variety of processes between -200°C and 1600°C. The maximum operating temperatures given in the catalogue apply to the air where there are no corrosive gases. In general the thermowells chosen for the installation is governed mainly by the corrosion conditions the well will face. The high polish given to all stainless wells provides maximum corrosion resistance. Occasionally, the material consideration is one of the strength rather than corrosion resistance.

Below are some types of each cateogry.
