Applications
- Gas Sensing and Monitoring Features and Benefits
- TO-5 metal housing
- Selection of narrow band Filters
- Thermal Compensation Product Description The LHi 807 TC series has become a standard solution for gas-sensing applications. It is available with a range of narrow band filters, as specified on page 4 of this brochure, for various gas species. The LHi 807 is usually supplied with temperature compensation by a separate “blind” sensing element. Similar features and benefits are included with the PYS 4198, which has a large element size of 2x2 to offer more signal for non-focused optical systems. It is offered with the thermal compensation element to compensate for thermal effects caused by temperature changes of the housing.
