Bimetallic thermometers are spherical thermometers that measure the temperature through a bimetallic spiral that rotates depending on the temperature thanks to the constant distance of dilatation of the two metals.
Bimetallic thermometers consist of a graduated sphere where the position of the needle shows the temperature and a bulb where is placed the bimetallic spiral.
The accuracy of the system goes between a 1 and 2%. The constrictive characteristics offered by SENSOTEC instruments in the rang of bimetallic thermometers is the following:
-Sphere diameter. We offer diameters between the 26 mm and 150 m.
-Bulb diameter and length. Diameter from 4 mm to 9,5 mm and length up to 1000 mm.
-Connection. Thread connection between 1/4” and 1” GAS NPT or metric thread.
-Thermometer shape. We have different types of inmersor output. Vertical output, for the lower part of the bulb, rear output centred, salida posterior acodada or rear articulated output where the angle can vary.
-Measurement temperature. The bimetallic system enables measurement between -70 and 600ºC.
