This Pt 100 Ex sheathed resistance thermometer has been particularly designed for use in potentially explosive areas. As it meets the requirements of the EEx m type of protection, intrinsically safe circuits can be dispensed with. Thanks to the pliable part of the resistance thermometer, the device is excellently suitable for application areas requiring a high degree of flexibility and replaceability (e.g. chemical and power plants).Structure
The resistance thermometer is made of a 3 mm thick light plastic-sheathed cable with different lengths. This light plastic-sheathed cable is filled with magnesium oxide. The pliable part of the resistance thermometer starts after 50 mm. Via a transition gland, the connection to a flexible supply cable is created.Function
Metals increase the electrical resistance with rising temperatures. The platinum element of the resistance thermometer has a resistance of 100 Ohm at 0 ?C. This characteristic is used for this type of resistance thermometers to get an image of the temperature. The resistance changes of the Pt 100 Ex are converted into a temperature value and displayed by a control unit.Tehnilised andmed (väljavõte)
