OMEGA’s new Wireless Relative
Humidity transmitter features a
stand-alone, compact, battery
powered NEMA design that
transmits measurements back to
a host receiver up to 90 m (300')
away. When activated the wireless
transmitter will transmit readings
continuously at pre set time interval
that was programmed by the user
during the initial setup. Each unit
measures and transmits: Relative
Humidity Reading, Ambient
Temperature, RF Signal Strength
and Battery Condition to the
receiver and is displayed on your
PC screen in real time using the
provided software. When used
with host receiver model UWTC­REC1 data from up to 96 wireless
transmitters can be received and
displayed. Each unit includes free
software that converts your PC into
a strip chart recorder or data logger
so readings can be saved and later
printed or exported to a spread
sheet file. When used with host
transceiver model UWTC-REC2

wireless data from one unit can be
re-transmitted out of the receiver
by a wired connection as a analog
voltage or current signal to interface
with a controller, PLC or data
acquisition board.
