OS-TX-USB-Series
Fixed IR Temperature Transmitter with
4-20 mA and MODBUS over USB outputs
OS-TX-USB-Series infrared pyrometers
measure temperatures from -40°C to 2000°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 or data logger.
Offers easy connection without the need for
special interfacing or signal conditioning.
General-purpose (8-14 µm) models can
measure from -40°C to 1000°C. They are
suitable for measuring high-emissivity materials
such as paper, thick plastics, food,
pharmaceuticals, rubber, asphalt and painted
surfaces. These models are capable of
measuring very low temperatures, so they are
ideal for sub-zero measurements in the food,
logistics and storage industries.
Short-wavelength (2.2 µm) models have a
choice of temperature ranges from 45°C to
2000°C. They provide a more accurate reading
when measuring low-emissivity materials such
as many reflective metals. They are also
capable of measuring through glass viewports.
All models have USB communications. A USB
cable is included and free software is available
to download from the Omega website.
Data is transmitted via Modbus, so it is also
easy to configure and read temperatures from
the sensor using third-party software.
The USB cable has an IP65 connector at the
sensor end, and an IP65 cap protects the
sensor when the USB cable is not connected.
