OMEGA’s new infrared sensor with wireless transmitter features a remote IR sensor and radio wireless transmitter in a NEMA enclosure. The miniature sensor head is ideal for measuring temperatures from
-18 to 538°C (0 to 1000°F) in confined, hard-to-reach places and harsh environments. The wireless transmitter is mounted in a NEMA 4X (IP65) plastic enclosure. When activated the unit will transmit readings continuously at pre-set time interval that was programmed by the user during the initial setup. Each unit measures and transmits IR sensor reading, ambient temperature, RF signal strength and battery condition to the host and is displayed on the PC screen in real time. Each compatible “UW” Series receiver 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.
