The DMA572 Thermohygrometer by Lsi-Lastem was installed on 2007 on Dosdè station. It is a probe for measuring air temperature and air relative humidity with replaceable sensitive element for simplify calibration and maintenance. LSI-Lastem supplies a precise and reliable set of probes, suitable for a continuous measurement in severe environments, in presence of deep thermal and hygrometric ranges with high sun radiant heat. An important feature of this set of sensor is that the thermohygrometric sensitive element is easily replaceable, in order to have a simple and rapid ordinary maintenance and avoiding calibration. The Thermohygrometer has supported a considerable improvement, owing to a deep technical and styling development process: a fan ensures a continuous air change around the sensor in order to eliminate temperature fault caused by radiant heat. DMA572 Specifications: Power supply: 10 – 14 Vdc Power consumption: 2 mA R Load Max (mA output) : CE compliance : EMC standard EN50081-1, EN50082-1 Electric protections: tranzorb, on outputs and power supply Housing: alluminium Weight (cable attached): 440g Connection cable: L. 5 m Temperature Range: -30÷70°C, -50÷50°C, 0÷100°C Sensitive element: Pt 100 1/3 DIN-B Sensitive element replacement: ML3021 Plug-in by connector Accuracy (repeatability+hysteresis): ± 0,1°C (0°C) Electronic accuracy: ± 0,15°C Operating temperature: -40°÷95° Output: Pt100 (Ohm) Relative Humidity Range : 0÷100% Sensitive element: Capacitative Sensitive element replacement: ML3021 Plug-in by connector Accuracy (repeatability+hysteresis): 1,5% (5÷95%, 23°C) * 2% (<5>95%, 23°C) * Resolution: 0,12% Long term stability: <1% year Temperature dependence (+6+45°C/ 11-90% RH): ± 1,5 % Operating temperature: -40° ÷95° Output: 0÷1V
