The LT-IRP infrared temperature sensors offers intelligence in a rugged, easy-to-use package. The LT-IRP is centered around a high-speed microprocessor that continuously monitors and adjusts the complete system. While performing the complex algorithms determining the output, it calibrates itself about once every second, removing any concerns over drift or sudden changes. Other advanced features include emissivity shift compensation and ambient radiation error correction. The rugged housing withstands thermal and mechanical shocks. The built-in air purge prevents dust, dirt, or condensing vapors from depositing on sensor optics, assuring long-term accuracy under all environmental conditions. The integral heat exchanger eliminates drift by automatically warming (or cooling) supply air to match the optical aperture temperature.
The delivery set includes the LT-IRP sensor with the 1-m air conduit and the air purge pump.
Standard output cable length is 4 meters.
Every sensor is individually tested and calibrated within the measurement range.
