Oven Web Temperature

Oven Web Temperature Censor Interface Enclosure

Oven Web Temperature Censor Interface Enclosure

Precise, repeatable measurement and control of material temperature while in an oven can offer marked improvement in a line’s productivity, energy costs and product quality.  In the drying process of solvent and aqueous coatings on films, papers, textiles and other webs, material may span well over 100 feet and remain in the oven over several minutes.  Ensuring that the web temperature is in specification during this time can be the difference between making high quality product or scrap.  Harsh, high temperature oven environments require robust sensor designs.

We offer oven web temperature measurement sensors that feature:

  • Intrinsically safe, non-contact, sensor design that is suitable for use in EXP (Solvent) or Non-EXP (Aqueous) environments

  • Two sensor designs:

    • Standard Temperature design for webs from 0-250°C (32-482°F)

    • High Temperature design for webs from 0-426°C (32-800°F)

  • Measurements that are insensitive to different material colors and clarity.  The measuring principle is based on exchange of thermal radiation between the material to be measured and the temperature sensor’s surface.  This is not an IR device – excellent measurements on clear films.

  • Real time response

  • Resistive to soiling

  • No calibration required after initial set up

  • Insensitive to condensation

  • Typical measurement accuracy: +/- 1%

  • Measurement Signals: 0/4-20mA or RS485 Serial Communications (Modbus)

  • Multiple sensors are normally fitted along the length of the oven and/or several sensors are applied in a single cross direction row for left – center – right web temperatures monitoring

  • Sensor Stand-Off Distance to Material: 20-120 mm (0.8-4.7”)

Temperature Sensor Stand-Off Distance / Measurement Diameter

 

  •  Circular temperature measurement area on material is based upon the material stand-off distance from sensor:

    • 140 mm (5.5”) measurement diameter at 20 mm (0.8”) stand-off distance from web

    • 300 mm (11.8”) measurement diameter at 60 mm (2.4”) optimal stand-off distance from web

    • 550 mm (19.7”) measurement diameter at 120 mm (4.7”) distance stand-off distance from web

  • Straight forward installation - Sensor cables, mounting brackets, oven grommets and sensor interface enclosure are included as necessary with all quotes
