  • Page 4: 2Note

    TWL 4 Regulation Use The temperature sensors of series TWL are suitable for all applications where processes involving fluids, solid bodies or materials, or gases, require temperature recording and measurement. Our temperature sensors are suitable for use in the following industrial areas: chemicals, petrochemicals, water, feed, food, sanitary, etc.
  • Page 5: 5Operating Principle

    5 Operating Principle Resistance thermometers work by using the continuous change of resistance of metals subject to temperature rising and decreasing. The most common resistance material used is platinum, as it is very stable and has very good repeatability. The temperature coefficient of platinum is positive, so its resistance increases as the temperature rises.

  • Page 7: 7Use In Hazardous Areas

    This measuring principle acts to check and measure the temperature also in explosion-proof areas. TWL devices can be with a standard 4 to 20 mA signal transmitter, Hart protocol, Profibus/Fieldbus or with direct access to the sensor. They are appropriate for use in Group IIC and Categories 2G/D explosion-proof atmospheres.

    - Do not install the device near material airflows or near steam outlets 7.5 Maintenance and repairs The instrument does not require maintenance or servicing. Repairs must be only carried out by Kobold Mesura (manufacturer) 7.6 Storage Measuring instruments should be protected against humidity and dust.
