Installation and maintenance - of bimetallic thermometer is analysed Shanghai dragon instrument electric appliance co. , LTD

Bimetallic thermometer is in custody, installation, use and transportation process, should try to prevent collision pipe maintenance, do not make. To protect the tube bending and deformation. The device, it is forbidden to twist instrument shell. Instrument should be in - 30 ℃ ~ 80 ℃ environment temperature in normal work. Instrument can often work temperature * good at 1/2 to 3/4 of scale range. Bimetallic thermometer maintenance tube immersed in the measured medium length must be greater than the length of the thermal components, common in greater than 100 mm in length, 0 50 ℃ range into greater than 150 mm in length, to ensure the accuracy of measurement. All kinds of bimetallic thermometer should not be used to measure open containers within the medium temperature, electric contact thermometer should not be in the control loop of vibration larger workplace. Bimetallic thermometer in custody, using the device and transportation, should prevent collision pipe maintenance, do not make the maintenance of tube bending variant and use table when the wrench. Thermometer in normal use shall be under the condition of periodic inspection. It is advisable to common to every six months. Electric contact thermometer is not allowed to work under intense shaking, lest affect the strong sexual contact. Should be paid attention to for the installation of the bimetallic thermometer, temperature measurement accuracy, safety examination and maintenance is convenient. And do not affect the equipment operation and production operations, to meet the above requirements, in the choice of thermal resistance of the installation site and insertion depth should pay attention to the following: in order to make the measurement of thermal resistance end and had good heat exchange between the measured medium, should choose the observation points, try to avoid the valve, elbow and pipe and equipment near the corner of installing heat resistance.
