Indoor air quality Dual Wavelength NDIR measurement methods Range 0...2000 ppm CO2 Ad in 6 stages over LED green-yellow-red Output 0/4...20 mA or 0...10 V Wall enclosure for mounting on flush-mounted switch box Power supply 24 Vac or 24 Vdc Better air quality reduces fatigue and loss of concentration! In many environments, the motivation decreases when the air quality deteriorates. The simplest solution is to open a window! However, this is not in any work environment possible. The CO2 monitor CM2 helps to keep the air quality at a constant level and to counteract fatigue. It measures the CO2...

Eisdicke erreicht Controlled ice production for cooling purposes Combination of sensor and evaluator Ice thickness selectable by 4 stages Changeover contact when reaching the preselected ice thickness The ice thickness controller – EDR2 improves the automatically production of ice. Vorwahl Eisdicke Normally, ice is produced, in a filled basins in which cooling plates are positioned. On those plates ice layers grows continuously till the freezing process is switched off. A continuous constant ice thickness cannot be achieved via the conventional method. The EDR2 was developed in order to improve...

O2T - flue gas tester for O2 Oxygen measurement directly in the flue gas Outputssignale for O2-content and flue gas temperature The flue gas analyser O2T is a transducer for measuring the oxygen content and temperature of the flue gas. The transmitter operates with a zirconia probe for O2 determination and with a measuring resistor Pt100 for temperature measurement. It is installed directly into the flue gas duct. A gas treatment is not required. Specifications Measured armature: Case: Weight: Supply voltage: Power consumption: EMC: stainless steel pipe, D=60mm, lenght 250mm stainless steel tube,...
