The OS151-USB Series measures temperatures
from -40 to 1000°C (-40 to 1832ºF) accurately and
consistently, with an outstanding response time of
240 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
OS151-USB has 15:1 optics making it suitable for most
applications. OS301-USB is specially designed for
distant targets and has an optical resolution of 30:1.
OS801-USB is designed for small targets and
measures a spot size of 5 mm (0.20") diameter at
100 mm (3.9") distance. All 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 an OPC (open process control) 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.
