Measuring technology for explosive areas
September 2004
Maintenance, Test & Measurement, Calibration
From simple control measurements to long-term measurements with user-friendly data processing and analysis via PC, the new Ex range offers an ideal solution for every application in explosive areas. All products in this range are certified under the new Ex-protection-standard ATEX. The Ex range offers the following for hazardous/explosive areas:
High precision portable temperature measuring instrument: Ex-Pt 720 (Ex II2(1)G EEx ia IIC T4)
Its large measuring range (-50 to 400°C), high accuracy (within ±0,2 to ±0,5°C), 4-wire technology and the option to connect immersion, penetration or surface probes, the Ex-Pt 720 is a suitable handheld instrument for control measurements. Measured values are clearly readable on the large display and custom-made probes can be developed to suit extraordinary needs.
Professional data logger: Ex 171-0 (Ex II2G EEx ia IIC T4)
Robust and watertight, this temperature data logger in its (IP68) metal housing guarantees high measuring accuracy for long-term measurements. The Ex 171-0 can record up to 55 000 measured values, which cannot be manipulated. All recorded data is transferred to a PC-interface that is connected outside the explosive range. Graphical or tabular analysis of data is carried out via user-friendly software, Comsoft 3.
Electronic thermo hygrograph: Ex 171-3 (Ex II2G EEx ia IIC T4)
The thermo hygrograph has the benefits of the Ex 171-0 and also guarantees a high measuring accuracy for long-term humidity measurements. The Ex 171-3 is capable of recording up to 20 000 measured values which also cannot be manipulated. Control and calibration is possible via a calibration set.
Both the Ex 171-0 and Ex 171-3 have clear identification in the form of an explicit serial number. There is also the possibility of protecting the measuring program from unauthorised access with an instrument password.
