LTS-100 Laser Temperature Sensor
LTS-100
MetroLaser, Inc., an innovator in the field of laser-based instrumentation, has developed the LTS-100TM laser temperature sensor to enable measurement of gas temperatures up to 4000 °F with proper calibration.
Simple, Robust Design
The wavelengths of the LTS-100TM sensor are closely spaced and fall within the band used by telecommunications equipment. This allows a single communications-grade laser source to be used, leading to a simple, robust measurement system.
Insensitive to Obscurities
Obscurities in the beam path that may be caused by soot, dirty windows, or broadband absorption by other molecules are not a problem. Such obscurities have similar effects on each absorption feature, such that the absorption ratio remains constant. As a result, the LTS-100TM is essentially unaffected by these interferences.
High Temperature Capability
The highest measurable temperature is limited solely by the absorption characteristics of H2O molecules, since there is no physical contact with the gases being measured. Currently, the system has been validated up to 2800 °F, but future validations are planned for temperatures up to 4000 °F.
Physical Robustness
The laser beam is transmitted through a fiber-optic line that can be essentially unlimited in length. This property enhances the mechanical robustness of the system by allowing physical separation of the processing unit from the harsh combustion environment.
LTS-100 Laser Temperature Sensor
This laser-based sensor is well-suited for temperature measurement in the harsh environments found in power plants and aerospace, since the sensor is non-intrusive and has low sensitivity to particulates and other obscurities.
MetroLaser’s goals in marketing the LTS-100TM are to improve the reliability and quality of traditionally challenging high temperature measurements.
