The OS150-2USB Series of infrared pyrometers measures temperatures from 45 to 2000°C (113 to 3632ºF) accurately and consistently, with an outstanding response time of 240 ms. The selectable 0 to 20 mA or 4 to 20 mA output is compatible with almost any indicator, controller, recorder, data logger etc. without the need for special interfacing or signal conditioning. All OS150-2USB Series sensors are fully configurable from a PC using the OMEGA software and USB cable supplied. This user friendly software enables the user to set the temperature range and emissivity setting compensates for reflected energy; apply filtering; select max, min, average or instantaneous readings; and configure peak or valley hold processing. These features can also be monitored and adjusted by an OPC client. Other features include data acquisition, alarms and a scrolling graphical display. The sensor will operate with the 4 to 20 mA cable connected, the USB cable connected, or both. The USB cable has an IP65 connector at the sensor end. An IP65 cap protects the sensor when the USB cable is not connected.
