DESCRIPTION

The Kele KHR, KHD, and KHO Series Humidity Transmitters

are speciﬁcally designed for use in HVAC/BAS applications. These

instruments measure relative humidity from 0% to 100%. The

standard two-wire, 4-20 mA output provides low-cost humidity

monitoring for building control. The RH transmitters are available with

thermistor or RTD temperature sensors. They come in room (KHR),

duct (KHD), and OSA (KHO) mounting styles.

FEATURES

• Calibration-free interchangeable sensors

• Twelve-point computerized calibration

• ±2% accuracy (5% to 95% RH)

• Replaceable sensor probe (no re-calibration)

• No need to remove box to replace sensor probe

• Attractive room enclosure design

• Two-wire, 4-20 mA output, 0% to 100% RH

OPERATION

The transmitter converts the relative humidity into a 4-20 mA

signal with the latest microprocessor capacitive design. Multipoint

factoryautomated calibration improves accuracy and repeatability.

The optional temperature sensors, thermistor or RTD, offer direct

connections to most automation systems.
