LHi807 Datasheet PDF

APPLICATIONS

● Gas Sensing and Monitoring

FEATURES AND BENEFITS

● TO-5 metal housing
● Selection of narrow band Filters
● Thermal Compensation Product

DESCRIPTION

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. LHI 807 TC and PYS 4198 TC Parameter Responsivity, min.
