The types of thermocouples

A thermocouple consists of two dissimilar metal wires connected at one end. When properly configured, is provided by measurements in a wide temperature range. Known for its versatility as temperature sensors thermocouples are manufactured in many different versions: a normal conductor, with connectors, adapters, infrared etc.

Calibration

Thermocouples are available in different combinations of metals, usually, there are two versions — for normal measurements and increased accuracy. To select the thermocouple you need to perform the pre-calibration temperature measurement to determine the measurement accuracy and set the acceptable error. Each calibration is calculated for the temperature range and the type of environment, although the maximum temperature depends on the diameter of the wire used in the thermocouple.

How to choose a thermocouple

The selection of the suitable thermocouple is made in the following sequence:

  • Defines the node or device, which will operate the thermocouple;
  • Analyzed the highest temperature range, which will be measured by the thermocouple;
  • Sets the durability of the thermocouple and its ability to withstand adverse external conditions (usually it is chemically aggressive environments);
  • Evaluates the durability and operability of the thermocouples in the conditions of vibration and shock loads;
  • Take into account the requirements for mounting thermocouples (must be compatible with existing equipment: holes, cavities, etc.).

Time constant is defined as the time required for the sensor to reach 63.2% of a step temperature change in a given set of conditions.

Technical characteristics

Thermocouple open connection ensures a quick response. The smaller the diameter of the sheath of the probe, the faster the response, but the maximum temperature may be lower. Thermocouple with sheath is available with one of three junction types: grounded, ungrounded or open. At the tip of the grounded jumper probe wire thermocouple is physically attached to the inside of the wall of the probe. This leads to heat transfer from the outside, through the wall of the probe in the connection of the thermocouple. In an ungrounded probe connection thermocouple detaches from the wall of the probe. In recent years a proliferation of wireless thermocouple, which connects to a smartphone or tablet to record and control temperature measurements. These transmitters measure different sensor inputs, while data transmission is wireless via Bluetooth technology to a smartphone or tablet with the app installed.
