Temperature Sensors: Plastic Applications Thermocouples

Transcription

1 emperature Sensors: Plastic pplications hermocouples he Plastic, Rubber and Packaging Industry sensors contained in the following pages are the most commonly used sensors in these three industries. he hermocouple and RD measuring elements all have insulated fiberglass leads inside the various sheath configurations. ll are rated for use up to 900 F () maximum temperature. Some applications, because of higher temperature demands, physical abuse, grounding problems, or other problems particular to a given process, may require the use of a MgO insulated type of sensor construction. he process may also require a special construction type of sensor to solve a particular application problem. Our team of engineers invite your inquires to solve your sensor application problems. Helpful Hints Generally, plastics industry thermocouples are type, and are enclosed in Stainleess Steel sheaths that are 3/16 in diameter. Plastics industry sensors are not to be used in process applications above 900 o F (700 o F for type ), as their construction uses 900 o F rated fiberglass insulated thermocouple wire inside the sheath. Use stranded conductor leadwire where continuous or frequent flexing of the leads occur. Ungrounded thermocouples are demanded in many applications due to MF stray and instrument grounding requirements. Most plastic instrument sensors can be supplied with this option, but in some cases a MgO insulated type of thermocouple may be required. he use of sensors with short leads, used in conjunction with extensions connected to permanent instrument connected junction boxes of jack panels, may be desirable in high sensor replacement applications. he cost of replacing long leads with each sensor replacement may not be cost effective. Our adjustable immersion G3 and H3 styles will replace almost all fixed bayonet style sensors as long as the lead length and cold end terminations are compatible with the sensors currently being used. RD sensors usually are the DIN Standard with a.00385α temperature coefficient. Hot tip immersion with RD sensors usually require a minimum immersion of 1 1/4 because of length of the RD measuring element inside the sheath.
