Humidity Sensor 2% Accuracy RH Overview

Wall-mount humidity sensor with 2% accuracy for relative humidity. This sensor requires external power from RIM-1000 or an external power supply and attaches to one of the analog inputs on the RIM-1000.

Key Features and Benefits

• Operating Humidity Range: 0-100% RH noncondensing
• Input Power: 4-20mA mode: loop powered 12-30VDC only, 30mA max. or 0-5VDC/0-10VDC mode: 12-30VDC/24VAC, 15 mA max.
• Output: 4-20mA mode: 2-wire, not polarity sensitive (clipped and capped); 0-5VDC/0-10VDC mode: 3 wire, polarity sensitive
• Humidity Sensing Element: Digitally profiled thin-film capacitive (32-bit mathematics)
