2 Resistance Thermometers according to DIN TWL Exia Description The KOBOLD resistance thermometers model TWL comprise a rugged installation fitting made of stainless steel with thread, flange or weld-on, a form B out of aluminium casting and a removable measuring insert (exceptions are models TWL-ST, -SN and -SA). The measuring insert can be replaced without emptying the process (TWL-ST, -SN, -SA excepted). The instruments are supplied with the ignition protection Exia as a standard and therefore can be installed in relevant hazardous areas. A Pt 100 temperature sensor according to IEC 751, category A or B is fitted in the measuring insert as standard. Depending on customer request the temperature sensor can be carried out as 2-, 3- or 4-wire circuit. Alternatively these sensors can be designed as single or double resistance thermometers. Exceptional the 4-wire version, which can only be build with one Pt 100 due to lack of space. As an option the resistance thermometers can be supplied with a. Transmitter with a standard 4-20 ma signal and with or with Fieldbus are there to choose from. Beside the available resistance thermometers according to DIN-standard, there are customised versions relating to the immersion, the, the materials, the process or the tolerance classes deliverable on request. Transmitter Resistance thermometers with are used whenever a measuring signal must be transported long distance without any disturbance. The which is encapsulated in epoxide resin is located right in the and delivers a temperature-linear output signal of 4-20 ma. The is available with standardised communication systems just like or Fieldbus. Applications The resistance thermometers are favourably used for the temperature measurement in liquids, solids and gaseous media. The reliable watertightness of this installation method for gauge pressure and vacuum is an important criteria for selection. Application areas are located in the air-conditioning and cooling industry, the heating-, furnace-, mechanical- and apparatus construction as well as in the complete industry. For all applications in hazardous areas, the instruments are supplied with the ignition protection Exia.
