Bimetal thermometers or gas-actuated thermometers ? the decision on the sort of thermometer alone depends on several factors. Probably the most important selection criteria may be the response time of the measuring Instrument.<br\/>With regards to speed, there is no way around gas-actuated thermometers. Generally of thumb, these thermometers take about 30 seconds for a temperature adjustment from 10\u00ef\u00bf\u00bdC to 90\u00ef\u00bf\u00bdC.  <a href=\"http:\/\/protectdefenderhub.xyz\">\u0e40\u0e01\u0e08\u0e27\u0e31\u0e14\u0e41\u0e23\u0e07<\/a>  would display the same final value after 90 seconds. Due to their short response times, gas-actuated thermometers are particularly suitable for integration into switching requirements.<br\/>The difference in speed is explained by the various functional principles of the two thermometer types ? unlike the bimetal thermometer (which uses the principle of different expansion coefficients), the measuring system of a gas-actuated thermometer is filled with helium under pressure. Any change in temperature causes an instantaneous change in internal pressure in the stem. The pressure deforms the measuring tube and the deflection is used in the pointer with a movement.<br\/>Thermowells affect the response time<br\/>Much like other measuring instruments, in critical processes, mechanical thermometers must be combined with a thermowell. It must be considered that such a sleeve may also have an influence, to some extent significant, on the response time of the thermometer. To what extent, depends on the material and wall thickness of the thermowell.<br\/>Note<br\/>Further information on mechanical thermometers can be found on the WIKA website beneath the headings Dial thermometers and Thermometers with switch contacts.<br\/>See also our articles<br\/>Selection criteria for mechanical thermometers (2): process temperature<br\/>Selection criteria for dial thermometers (3): Capillary<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Selecting suitable mechanical thermometers for an activity is not an instant task.
