Digital Humidity Temperature Sensors
Honeywell HumidIcon™ Digital Humidity/Temperature Sensors have an industry-leading Total Error Band that provides the sensor’s true accuracy of ±5 %RH over a compensated temperature range of 5 °C to 50 °C [41 °F to 122 °F] and 10 %RH to 90 %RH. Total Error Band, which includes all sources of error that a sensor might see, effectively eliminates individual sensor testing and calibration, supports system accuracy and warranty requirements, helps to optimize system uptime, and provides excellent sensor interchangeability.
“The Honeywell HumidIcon™ Series’ industry-leading features and Total Error Band accuracy provide our customers with a real competitive advantage,” said Valerie Rothermel-Nelson, Global Product Marketing Manager for Honeywell Sensing and Control. “When you also consider its ultra small SOIC8-pin package and low energy use, this sensor simplifies installation and offers the lowest total cost of ownership.”
The new series offers industry-leading long-term stability of 1.2 %RH over five years. Many competitive humidity sensors need to go through a 12-hour at 75 %RH rehydration process (which requires special equipment chambers) to correct reflow temperature offset. The Honeywell HumidIcon™ device only requires a 5-hour rehydration process under ambient conditions (>50 %RH). This long term stability minimizes system performance issues, helps support system uptime by eliminating the need to service or replace the sensor during its application life, and eliminates the need to regularly recalibrate the sensor in the application, which can be inconvenient and costly.
The laser trimmed, thermoset polymer capacitive sensing element, and the element's multilayer construction (which provides resistance to most application hazards such as condensation, dust, dirt, oils and common environmental chemicals), help provide industry-leading stability and reliability.
