Overview
Pyroelectric detectors for GAS MONITORING Single-Element Pyro Detectors For Gas Monitoring LHi 807, PYS 4198 – High-Sensitivity Pyros 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.
