Can the expansion of the remote reading thermometer

Here small make up is not the suspense, expand remote reading of the thermometer is what? This is we often used to pressure type thermometer, small make up today and you introduce this thermometer. Pressure type thermometer is the use of sealed container of liquid, gas or saturated steam heated volume expansion and pressure changes as the signal. Its basic structure is made up of bulb, capillary and indicator of three parts. It is one of the earliest methods of temperature control applied in the production process. Pressure type temperature measuring system now is still on the instructions and control is widely used in the temperature measurement method. Pressure type thermometer is: the advantages of simple structure, high mechanical strength, is not afraid of vibration. The price is low, does not need external energy. Defect is: limited temperature range, generally in - 80~400℃； Heat loss due to slower response time; Instrument sealing system ( Bulb, capillary, spring tube) Damage is difficult to repair, must be replaced. Measuring accuracy are greatly influenced by environmental temperature, temperature package installation location, accuracy is relatively low; Capillary transmission distance limit. Pressure thermometer often work scope should be 1/2 - of the measurement range - 3/4, and as far as possible make the display tables and bulb in a horizontal position. Install it using the bulb installation bolt can make the temperature loss caused by inaccurate, when installation should be heat preservation processing, and try to make the bulb work without vibration environment. This thermometer is easy to use, remote reading, solved many site indicating thermometers can do, but the accuracy of the thermometer relative instructions given there will be slightly less than the thermometer, so we choose the thermometer, should choose which kind of, that is about as the case may be.
