Since the beginning of 2017, MIKE3, 20l Siwek sphere, Sipcon and Sippower are distributed together with Cesana AG. Formerly, these devices were supplied by Kühner AG (Birsfelden). TÜV SÜD Schweiz AG will be responsible for production and distribution of these instruments as well as providing training and support whilst Cesana AG will be responsible for software, technical development and organization of the traditional calibration round robin tests CaRo
Apparatus for determining the minimum ignition energy of dust/air-mixtures
For an assessment of the hazard situation in dust-processing installations, knowledge of the minimum ignition energy is indispensable. This value can possibly determine the extent and hence the cost of protective measures. The minimum ignition energy (MIE) is the lowest energy value of a high-voltage capacitor discharge required to ignite the most ignitable dust/air mixture. This characteristic can be determined according to international standards:
EN 13821: Determination of minimum ignition energy of dust/air mixtures
ASTM E 2019: Standard Test Method for Minimum Ignition Energy of a Dust Cloud in Air
EC 61241-2-3: replaced by ISO/IEC 80079-20-2:2016
ISO/IEC 80079-20-2:2016: Explosive atmospheres. Material characteristics. c
replaced by the SIPCON data acquisition and control system.
Up to 4 different test equipment can be run simultaneously while recording the respective temperatures of the substance. For processing and storing, data are transmitted to a standard personal computer. Results can be displayed and printed numerically and graphically. The software on the personal computer contains a wealth of functions to evaluate the test results. When switching off the personal computer, Sipcon continues on its own. Sipcon itself contains no manual control elements and is intended to be operated right beside the test apparatus, the sensors being directly connected to it. Up to 6 Sipcon units running up to 12 test apparatus may be connected to a personal computer by means of a simple network.
