Optical Temperature Sensor Spots

  • Contactless Optical Temperature Sensor Spots
  • For temperature measurements in closed containers
  • True Temperature Compensation of Optical Oxygen Sensor Spots
  • For oxygen measurements in closed containers
  • Works in gas and in liquids
  • >3 years shelf time 

The new optical temperature sensors from PyroScience are based on an innovative technology utilizing temperature-sensing properties of luminescent indicators. Optical temperature sensor spots allow contactless measurements within closed containers through a transparent window (plastic or glass). The sensor spot is fixed at the inner side of the window with e.g. silicone glue (SPGLUE). Several optical fibers and adapters are available for read-out of the temperature sensor spots with the FireSting devices from PyroScience. The contactless temperature sensor spots can be used for true temperature compensation of oxygen sensor spots from PyroScience, if both are glued into the same sample container and read-out simultaneously with a 2- or 4-channel FireSting devices.

Silicone Glue for Sensor Spots (SPGLUE). This silicone glue can be used for gluing sensor spots (e.g. OXSP5) onto the inner side of the containers, where the oxygen measurement should be performed in. Generally, every transparent silicone glue based on acetic acid can be used for this purpose. The actual delivered brand of silicone glue might differ from the product image.

     
 

Basic Spot Adapter (SPADBAS). Set of 4 basic spot adapters providing precise fixation for the optical fibers PICFIB2 or the optical fiber rod PICROD2 at transparent container walls. The spot adapter should be glued to the window with an appropriate adhesive (e.g. epoxy glue or silicone glue SPGLUE).

     
 

Lens Spot Adapter (SPADLNS). The lens spot adapter provides a precise fixation for the optical fiber SPFIB at transparent containers with a wall thickness of ca. 2-6mm. A flexible re-adjustable cable binder is included, allowing quick positioning e.g. on laboratory flasks. Not applicable if submersed in water.

 

     
 

Optical Fiber (SPFIB). The optical fiber SPFIB is used for connecting the spot adapters SPADBAS or SPADLNS to the optical oxygen meter FireStingO2. There are ST-connectors at both ends. Standard cable lengths of 1m or 2m are available.

 

     
 

Bare Optical Fiber (SPFIB-BARE). The bare optical fiber SPFIB-BARE is used for connecting the basic spot adapter SPADBAS to the optical oxygen meter. It has a straight cut polished fiber end, which has no metallic parts. Therefore, SPFIB-BARE can be used in water baths or salt water applications.
