The OS-TX-USB-series infrared temperature transmitters can accurately and consistently measure temperatures from -40 to 2000ºC (-40 to 3632ºF) and have an excellent response time of 200 ms. The sensor will operate with 4 to 20 mA, 2-wire output (loop-powered), the USB cable, or both. When using only USB output, no external power is required.

The free OmegaConfig software is a simple application that can be configured via the included USB cable, displayed in real time, graphed and recorded in CSV text files. User-configurable settings include 4 to 20 mA output scale, emissivity, average, peak / valley, and reflected energy compensation. MODBUS over USB communication also allows measurement data to be configured and read through other compatible applications or user-written software.

The USB cable has an IP65 connector on the sensor side. The IP65 cap protects the sensor when the USB cable is not connected.

Can this unit be calibrated?

Asked by: Jen1
It does not appear to have been calibrated in the past but send a follow up to temp@dwyeromega.com and it can be reviewed.
