4121-G-F-J, infrared detector, $2195.

2120-6-2516-T1-7-1-2 polymelt probe, $1170.

The 4121 Polymelt System offers a unique non-contact method of measuring polymer melt temperatures. Unlike thermocouples, its 10 millisecond response time provides unsurpassed real-time temperature data and tighter process control. Since the probe tip is flush with the barrel's ID, it “looks into” the melt and is completely non-intrusive, producing no error due to polymer shear effects or heat sinking.

This compact and rugged system allows maximum installation flexibility and requires a minimum amount of space for installation. The 4121 polymelt system offers a fast and accurate method to monitor polymer temperature in the extruder nozzle or barrel or in the injection molding cavity.

The polymelt transducer system incorporates a chopper stabilizing detector for drift free operation and is directly interchangeable with thermocouple instrumentation such as meters or controllers with cold junction compensation. The 4121 is manufactured using advanced laser

soldering technology and incorporates surface-mount devices for exceptional reliability and compactness.

The 4121 polymelt system consists of a patented polymer probe with a rugged, flexible fiber optic cable assembly. The probe tip contains an abrasion resistant sapphire window which is capable of withstanding 30,000 psi pressure. The standard Hastelloy tip allows use on more abrasive polymer materials. The fiber optic assembly easily connects to the transducer. The 4121 polymelt system output ties directly to dataloggers, process controllers, and recorders. It incorporates a digital emissivity control for precise and repeatable setting of emissivity.

Series 2120 standard polymer probe is available in lengths from 165 to 305 mm (6.5 to 12.00") and is installed as shown below. The fiber optic cable is permanently attached to the bolt assembly. The air purge fitting is at 90° from the probe body.

Series 2108 $1290

Series 2108 quick-disconnect polymer probe, measuring as small as 76 mm (3") overall, is used where the available mounting space is at a premium. The fiber bundle exits the probe at a right angle and is easily removable from the probe body by a knurled twist nut. Air purge fitting is at 60° from the probe body.
