General

Honeywell Humidity and Temperature Wall Mount Transducers, SCT Series, are an ideal environmental solution for indoor applications such as building automation and HVAC systems in residential and office buildings. The SCT Series utilize Honeywell HumidIcon™ humidity/temperature sensors to accurately and reliably sense humidity and temperature in the area to enhance user comfort.

The SCT Series offer a variety of options and features. The transducers can be equipped with or without a legible LCD display which shows the ambient temperature along with the relative humidity or dew point. The stylish cover trim is available in either silver or gold.

Standard output of humidity and temperature is either 4 mA to 20 mA or 0 V to 10 V. The temperature output signal may also be configurated with an NTC 10 kOhm, 20 kOhm or PT1000 sensor.

Features

• Enhanced accuracy:
  • ±4 %RH (10 %RH to 90 %RH at 25 °C), ±5 %RH (10 %RH to 90 %RH at 5 °C to 50 °C)
  • Enables the customer to potentially reduce/eliminate transmitter recalibration cost and supports and optimizes system accuracy and uptime
• Long-term stability:
  • Humidity: ±0.05 %RH typ. and ±1.2 %RH max. drift over five years
  • True temperature-compensated humidity element enables customers to potentially reduce/eliminate the transmitter recalibration cost with enhanced stability over next best alternatives
• Enhanced reliability: The humidity sensor element’s multilayer construction provides resistance to most application hazards such as dust, dirt, condensation, oils and common environmental chemicals, enhancing reliability
• Standard humidity output: 4 mA to 20 mA or 0 V to 10 V
• Cost-effective
• Choice of cover trim color (silver or gold)
• Full 0 %RH to 100 %RH measurement range
• Available with or without LCD display
