• Lens or mirror optics
• Ambient temperature compensation
Product Description
e module range of Excelitas consists of a thermopile sensor mounted on a PCB with a connector. e
PCB can also provide for optional features such as voltage regulation and a noise-reduction lter.
e module includes the integrated temperature compensation for a dened temperature environment
and the calibration to a certain object temperature range. Modules cannot be programmed individually
at the customer site. us, when ordering, the correct ambient and object temperature ranges need to be
specied.
For requirements of dened spot sizes, we oer sensors with a eld of view dened by optical
apertures, internal lenses or external mirror optics. e mirror orientation M(y) can be specied and
a protective external lter may be supplied with the module.
e module types are available with dierent versions of pcb P(x). For the external mirror version,
we supply the mirror in dierent viewing orientations M(y); y = L (le) / y = F (front) / y = R (right).
Customization: As the modules are always calibrated to target temperature range customized versions
are available.
For the various object temperature ranges we oer the following pre-calibrated modules:
External mirror types
• -20 ... 60° C: TPM 1T 0234 OAA060 P(x) M(y) • -20 ... 140° C: TPM 1T 0134 OAA140 P(x) M(y)
• -20 ... 250° C: TPM 1T 0134 OAA250 P(x) M(y) • -20 ... 180° C: TPM 1T 0134 OAA180 P(x) M(y)
Integral lens types
• -20 ... 60° C: TPM 1T 0236 L5.5 OAA060 P7 • -20 ... 120° C: TPM 1T 0136 L5.5 OAA120 P7
• -20 ... 180° C: TPM 1T 0136 L5.5 OAA180 P7 • -20 ... 250° C: TPM 1T 0136 L5.5 OAA250 P7
• -20 ... 300° C: TPM 1T 0136 L5.5 OAA300 P7
A temperature reference output is included. On request the modules can be supplied as an “OBA”
version, which is calibrated but without internal temperature compensation. In this case the customer
will do the temperature compensation externally with the use of the supplied reference output.
