DESCRIPTION

The Kele Series H_30K Humidity Transmitters have been

speciﬁcally designed for use with HVAC/BAS applications.

These instruments measure relative humidity from 5 to 90%

with 3% accuracy and produce a two wire, 4-20mA linear

output. All can come equipped with an optional passive RTD

or thermistor. The duct and OSA versions may also be ﬁtted

with a 4-20mA temperature transmitter.

FEATURES

• 3% accuracy (5% to 90%)

• Two wire, 4-20mA RH output

• Optional temperature thermistor

• Optional temperature RTD

• Optional temperature 4-20mA (Duct or OSA)

OPERATION

The temperature compensated circuitry converts the relative

humidity into a 4-20 mA signal. The optional temperature

sensors, RTDs or thermistors, offer direct connection to most

automation systems. On duct and OSA units, an optional 4-20

mA temperature transmitter may also be employed and is

rangeable from -30° to 250°F (-34° to 121°C).
