Heater for optical gas sensors, gas sensors including the heater, and methods

A heater for use on an optical gas sensor including at least one window comprising:

• a heating element positioned over at least a portion of the at least one window of the optical gas sensor without being secured directly thereto, the heating element comprising transparent material positioned across an optical path of the optical gas sensor to provide a substantially unobstructed optical pathway through the at least one window.

A transducer for use in an optical sensing technique for measuring at least one gaseous or vaporized material, the transducer comprising:

• a transducer body configured to be removably secured to an optical gas sensor;
• and
• a heating element that is substantially transparent to al least one wavelength of electromagnetic radiation coupled to the transducer body.

A transducer for use in an optical sensing technique for measuring at least one gaseous or vaporized material, the transducer comprising:

• a transducer body configured to be removably secured to an optical gas sensor;
• and
• a heating element coupled to the transducer body, the heating element having a configuration that permits a substantially unobstructed optical pathway through at least one window of the optical gas sensor upon assembly of the transducer with the optical gas sensor.
