Please note this series has been upgraded to the new A models which are dimensionally different to the previous models. See dimension drawing below

The OS301A-USB Series measures temperatures from -40 to 1000°C accurately and consistently, with an outstanding response time of 200 mS. The 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.

OS301A-USB is specially designed for distant targets and has an optical resolution of 30:1. The OS801A-USB is a close-focus model, designed for small targets and measures a spot size of 5 mm diameter at a distance of 100 mm.

All of these sensors are fully configurable from a PC using the software and USB cable supplied. This user friendly software enables the user to set the range and emissivity, compensate for reflected energy; apply filtering; select max, min, average or instantaneous readings; and peak or valley hold processing. These features can also be monitored and adjusted by MODBUS over USB communications, allowing use with other software. 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.
