WSS-501 Φ150mm Dial Diameter Axial Installation Bimetal thermometers are widely used, and different application fields have different requirements for bimetal thermometers. Therefore, everyone must pay attention when purchasing, then what factors should be considered in advance for purchasing? The most basic of course is the classification of bimetal thermometers. Let me introduce you to the selection of bimetal thermometers. Classification of bimetal thermometers:
According to the connection direction of the bimetal thermometer dial and the protection tube, the bimetal thermometer can be divided into four types: an axial type, a radial type, a 135° type, and a universal type.
Axial type bimetal thermometer: The pointer plate is connected perpendicularly to the protection tube.
Radial type bimetal thermometer: The pointer plate is connected in parallel with the protection tube.
135°-oriented bimetal thermometer: The pointer plate is connected to the protection tube at 135°.
Universal bimetal thermometer: The angle of connection between the pointer plate and the protection tube can be adjusted freely.
In order to meet the needs of actual production, bimetal thermometers have different mounting and fixing forms: movable externally threaded pipe joints, movable internal threaded pipe joints, fixed threaded joints, ferrule threaded joints, ferrule flange joints and fixed flanges. Selection considerations:
(1) When selecting a bimetal thermometer, it is necessary to fully consider the actual application environment and requirements, such as dial diameter, accuracy grade, installation and fixing method, type of medium to be tested, and environmental hazard. In addition, we must pay attention to factors such as cost performance and maintenance workload.
(2) During the transportation, installation and use of the bimetal thermometer, the temperature probe should be avoided. To ensure the accuracy of the measurement, the length of the probe inserted into the measured medium should not be less than 2/3 of the length of the probe. Do not twist the instrument case.
