HS Element Digitally profiled thin-film capacitive (32 bit mathematics) U.S. Patent 5844138 Accuracy at 25°C from 10-80% ±1% at 12-60% RH (Multi-point calibration NIST traceable)Reset Rate** 24 hoursStability ±1% @ 20°C (68°F) annually for two years Operating Humidity Range 0 to 100% RH (non-condensing)Hysteresis 1.5% typicalLinearity Included in accuracy spec.Temperature Coefficient ±0.1% RH/°C above or below 25°C (typical)Analog Output 4-20mA mode: 2-wire polarity insensitive (clipped and capped); 0-5V/0-10V mode: 3-wire observe polarityScaling 0-100% RHOperating Temperature Range 10° to 35°C (50° to 95°F) Input Power*** 4-20mA mode: loop powered 12-30VDC only 30mA max.; 0-5V/0-10V mode: 12-30VDC/24VAC 15mA max.Temperature Transmitter Output Digital 4-20mA (clipped and capped) or 0-5V/0-10V output; accuracy ±0.5°C (±1°F) typical*Specified accuracy with 24VDC supplied power with rising humidity. RTD/Thermistors are not compensated for internal heating of product.**Reset Rate is the time required to recover to 50% RH after exposure to 90% RH for 24 hours.***One side of transformer secondary is connected to signal common so an Isolation transformer or dedicated power supply may be required.Shielded cabling is required for conformance to EMC standards.
