Specialty Gas Dynamic Sensors

Description

Physical Sciences Inc.'s (PSI) TDL Technology enables more than trace gas concentration measurement! Using precise spectroscopic techniques, absorption from individual molecules can be used to determine gas gemperatures and velocities. Simultaneous measurements of density, temperature, and velocity are reported with a 10 Hz bandwidth. Customized units, based on the TDL-1002 architecture, have been delivered to customers around the world, ranging from industrial furnaces to military flight vehicles. Any gas molecule detectable with the TDL-1002 architecture can be used for simultaneous gasdynamic measurements.
