1 Relative Humidity Transmitters Standard Accuracy Series 730,732, ± 2% RH or Low Cost 733 and 734 Design ± 3 % RH Analog : 2-Wire (4-20mA) or User-Selectable (0-1V, 0-5V, 0-10V or 0-1mA) CE-approval TYPICAL APPLICATIONS Energy management Food Processing Bakery Products Tobacco Greenhouses Paper HVAC Textiles Warehouses Fruit Storage Clean Rooms Museums Grain Storage Meat Storage The Relative Humidity Transmitter continiously measures the ambient humidity and provides an analog output directly proportional to the Relative Humidity. The output signal is given from 0-100% RH. The 2-wire model provides a passive 4-20mA output requiring a current loop supply of 8-30Vdc. The outptu of the 3/4-wire model is userselectable: 0-1V, 0-5V, 0-10V or 0-1 ma. (The unit is factory set at 0-10V). The Relative Humidity Transmitter can be combined with a temperature transmitter or a single Pt100 or Pt1000 element. Customized versions on request The transmitters are available in a standard accuracy of ± 2 RH or as a low-cost version with an accuracy of ± 3 %RH between 30 %RH and 80 %RH. Options include teflon and stainless steel filters to protect the sensors in dusty environments, a weather protection cap for Meteo applications; and a mounting flange.
