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 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. When used with host receiver UWTC-REC1, data from up to 48 wireless transmitters can be received and displayed. Each compatible receiver 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
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.
