Table 1

Thermopiles model PU 22T of the TNO (Delft).

Dimension of PU-T category of 1 mm thickness: sensitive area (), guard (), fixed wires (), minimum bending radius (),
and optional temperature sensor ()
Note: PU-T sensors can be bent but are quite rigid. Installation typically requires taping.
