· Most thermometers used in analytical application are bimetal types that are simple to use and rugged. Occasionally, however, remote reading vapor, gas actuated, or mercury thermometers are required. Your AnalyzerComponents.com representative can help you find the exact thermometer that will best meet your requirements.
· Like a bimetal thermometer, a thermocouple uses two dissimilar metals welded together to measure temperature. A small voltage between these two metals varies with temperature and this is converted to an electrical signal. Thermocouples are relatively rugged and inexpensive. AnalyzerComponents.com can help you find the best thermocouple for your application.
· Temperature switches can be used for simple jobs where an alarm is sounded or a process is turned on or off when a temperature set point is reached. These can be provided with analog or digital displays. AnalyzerComponents.com can help you select the right switch for your application.
· Temperature controllers are really small computers. Typically working off thermocouple or RTD input, these devices can be programmed to hold temperature for a given time, then raise or lower it, and then continue to process the temperature output over multiple steps. They can also send out remote signals for alarms or to turn on or off remote equipment. The choices are many - so ask your AnalyzerComponents.com representative for help in selecting the controller that will best meet your needs.
· Temperature transmitters, typically using a thermocouple or RTD input, can send a variety of output signals to local or remote displays. Your AnalyzerComponents.com advisor can help you select the best transmitter for your application.
· RTDs work on the principal that electrical resistance in the RTD's circuits changes with temperature. This information can be converted to a varying voltage signal that is generally more stable and accurate than that provided by a thermocouple - but at a slightly higher cost. Your AnalyzerComponents.com advisor can help you select the best device for your job.
· Using either steam or electrical resistance, heaters can warm a sample or enclosed space. Selecting the right unit requires information about the size of the space to be heated, ambient temperature, and insulation available. AnalyzerComponents.com personnel can help you find the most economical heater that will meet your job needs.
