The change in resistance of platinum in relation to the temperature to be measured is used for temperature measurement with the KOBOLD Pt 100 temperature sensors LTS. The devices are connected electrically with 2-, 3- or 4 -wire technology, depending on the input of the evaluation device and the line length. Alternatively, the thermal sensor can be connected to a 4 - 20 mA current input (2-wire current loop) through the built-in 2-wire transmitter. The temperature sensors with a connection that is cavity free (...T, ...M) are fitted with a food-compatible metallic sealing system, that forms a hygienic measuring point in conjunction with the associated weld-in sleeve LZE (confirmed by the EHEDG and 3-A report). The temperature sensors with neck well LTS-NH are suited for measuring permanently high temperatures (up to 250 °C). Sensor tips and response times All temperature sensors are available with tapered tips to ensure faster response times. The times specified below refer to a Pt 100 temperature sensor immersed in boiling water.
