Temperature measurement(THERMOMETER) is the most measured physical parameter and is found in almost every field in the industry in laboratories and research.
There are 4 main types of thermometers:
Thermocouple sensors - their technical marking:
Thermocouple sensors make over 90% of temperature meters(THERMOMETERS) in industry and laboratory research.
-There are several types of thermocouples made of different metals and designed for different temperature ranges,The thermocouples differ from each other in the temperature range they operate and their accuracy.-For different thermocouples insulations in different colors to differentiate between them. The colors are set according to international American, European and Japanese standards.
Thermometers (temperature loggers) for laboratories and industry are divided into five main types:
- Small pencil-shaped thermometers for the pocket in which the temperature sensor is built into one unit with the display.-Pocket thermometers are limited to a narrow temperature range of up to about 200 degrees Celsius- Used in laboratories and research to measure the temperature of liquids in ranges of up to 100 degrees Celsius,- Food plants are used to measure temperatures of up to 200 degrees Celsius (mainly in poultry factories)- In buildings and roads for measuring the temperature of asphalt up to 300 degrees Celsius.
Thermometers for measuring the temperature in the room for hanging on a wall and for measuring the temperature in the refrigerators
The temperature gauges come without the sensors that are purchased separately.- Temperature meters come with one or more inputs for temperature sensors (usually thermocouples),The advantage that a wide range of Thermometers can be connected to the same temperature sensors:Sensors for immersion in liquids, for measuring area,Stabbing sensors, flexible sensors, high temperature sensors and moreTemperatures can be measured with them in large temperature ranges from 200 - Celsius to 1800 Celsius.- The connection to them is standard with a mini connector with flat legs.
-When it is necessary to map temperature in incubators or any other heating device,The thermometer has several inputs, 2 or 4 or 12 or moreThe temperature in several points and see the differences in temperature.In many cases TEMPERATURE DATALOGGER is used That sample the temperature in a timely mannerThe most common temperature sensor is a K-type with a yellow connector that allows temperature measurements over a wide range of200- Celsius to 1370+ Celsius.
When a Precision Thermometer is needed Especially for calibration, use a thermometer with an RTD PT100 resistance sensor
They are less accurate and are designed for places that cannot be reached or touched with a temperature sensor
