Humidity - Room Recessed

  • 2 or 3% accuracy
  • 0-5V/10VDC RH/Temp (thermistors optional)
  • Field-calibration potentiometer
  • Durable and attractive low-profile design

Applications

  • HVAC room humidity and temperature measurement and control
  • Energy management/building control

Description

The HR series is designed for use in energy management systems in buildings. They combine excellent stability with reliable operation and provision to offset the RH reading +/-5% for in-field calibration. Thermistor options accommodate any installation. Housing is offered in multiple color choices to match any decor.

Attractive recessed design is attractive and durable

  • Match colors and existing interior decor
  • Fits in most standard wall plates
  • No exposed screws; unobtrusive tamper resistant design
  • Ideal for schools

Field calibration poteniometer

  • Field calibration scaled adjustment allows easy adjustment of calibrated RH value as needed to maintain certification.
  • 0-5V/0-10V output—jumper selectable

Choose from a range of accuracy and options

  • 2% and 3% RH accuracy options
  • Thermistor outputs for temperature optional

Superior RH sensing

  • On-board temperature compensation for RH. Eliminates temperature coefficient errors and achieves an excellent measurement accuracy as well as high repeatability and offset stability.

  1. One side of transformer, secondary is connected to signal common. Dedicated transformer is recommended.
  2. Time for reaching 63% of reading at 25° C and 1 m/s airflow.
  3. Long term exposures to conditions outside normal range at high humidity may temporarily offset the RH reading (+3%RH after 60 hours).
  4. 15-30VDC/24VAC power supply voltage required for 10 volt output.
