Measure Temperature in Fluids and Gases as well as Dusts by Using Weld in Resistance Thermometer

For Explosion-hazardous Areas zone 1, zone 2

Resistance thermometers TW85 are applied as intrinsically safe equipment to measure temperature in fluids and gases as well as dusts.

These thermometers consist of a protective sleeve with various process connections, a terminal head and – depending on model – an exchangeable gauge slide. All components in touch with process media are leak tested. Pt 100 temperature sensors acc. to DIN EN 60 751 in tolerance classes A or B in 2, 3 or 4-wire circuit are used inside the protective sleeve. Models with 2 measuring circuits are possible. To transfer measurement as standard signal (e.g. 4…20mA) a transmitter can be integrated into the terminal head. Depending on usage and measuring task resistance thermometers can be delivered with various terminal heads. The instruments are solely to be used with provided protective sleeve.

• Measuring element: Gauge slide acc. To DIN 43762
• Max. Media temperature: 450°C
•Insertion tube: dia. 11mm, 165mm long.
