OMEGAs new wireless relative humidity transmitter features a stand-alone, compact, battery
powered design that transmits measurements back to a host receiver up to 120 m (400') 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. 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.
The UWRH is compatible with the UWTC-REC family of wireless receivers, which can accept signals from
up to 48 wireless transmitters, and display them on a PC. Receivers are available with optional display
and analog output. An analog output can be used to interface with a process controller, PLC or data
acquisition device. Each unit includes free software that converts your PC into a monitor, chart recorder
or data logger. Readings can be saved and later printed or exported to a spreadsheet file.
