NBCIP ANNOUNCES FINAL REPORT ON PRODUCT TESTING OF DUCT-MOUNTED RELATIVE
HUMIDITY TRANSMITTERS
The National Building Controls Information Program (NBCIP) has released a
final report on the performance of relative humidity transmitters entitled
“Product Testing Report: Duct-Mounted Relative Humidity Transmitters”. This
product testing report can be downloaded from the NBCIP Web site at
www.buildingcontrols.org.
Because of their impact on energy use and the quality of the indoor environment,
NBCIP tested and evaluated the performance of resistive and capacitive
duct-mounted relative humidity transmitters used in typical building HVAC
applications. NBCIP developed an experimental procedure for testing the humidity
transmitters, and used this procedure to test products from six leading
manufacturers.
The NBCIP Product Testing Report provides an overview of factors to consider
when purchasing a humidity transmitter, presents manufacturer data for
transmitters selected for testing, describes the test procedure and test
apparatus used by NBCIP to evaluate transmitter performance, and presents test
results for accuracy, repeatability, linearity, and hysteresis for each humidity
transmitter model tested.
The Product Testing Report: Duct-Mounted Relative Humidity Transmitters was
developed with funding from our sponsors and is available free of charge. To
download a copy of the report, visit the NBCIP Web site at:
www.buildingcontrols.org.
The National Building Controls Information Program was created by the Iowa
Energy Center with support from the U.S. Environmental Protection Agency and
NSTAR Electric and Gas Corporation. NBCIP does not accept funding from product
manufacturers. NBCIP facilitates the adoption of energy efficient building
control products and strategies through testing, demonstration, education and
dissemination of product information. NBCIP provides unbiased, accurate,
reliable, manufacturer-specific information on building control systems to guide
and improve the selection, installation, operation and maintenance of control
products and strategies for building applications. |
