Pt100 Ex Resistance Thermometer
Ex Proof Heat Tracing Equipment - Pt100 Ex Resistance Thermometer
The device is perfectly suited for application areas that require a high degree of flexibility and interchangeability (e.g. chemical and power plants) and is specially designed for use in potentially explosive areas.
Pt100 Ex Resistance Thermometer
- Very fast response time
- Compact dimensions, compact design
- Wide temperature range
This Pt100 Ex sheathed resistance thermometer has been particularly designed for use in potentially explosive areas. As it meets the requirements of the Ex 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 mineral insulated cable with different lengths. This light mineral insulated 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 Ω 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 Pt100 Ex are converted into a temperature value and displayed by a control unit.
Application Areas:
- Oil and gas industry (refineries, platforms)
- Chemical industry (chemical plants)
- Mining
- Paint industry
- Flour and sugar factories
- High temperature furnaces (in hazardous areas)
- Heat treatment plants (in hazardous areas)
- Hazardous material storage
- Extruder Heating (in hazardous areas)
- Hot press applications (in hazardous areas)
- Heating cable applications (in hazardous areas)
- Sensor connections (in hazardous areas)
- All applications requiring temperature measurement in hazardous areas.
