L.J. Star, the leader in process observation equipment and technology, offers a complete line of sight glass accessories that corresponds with its complete line of sight glasses, lights, sanitary fittings and level gage instrumentation.

Metaglas® Sight Glass Discs are resistant to impact, pressure, thermal and mechanical stresses. Metaglas prestressed glass provides reliability against total failure, simplified installation, and extremely long and continuous service. And Metaglas can be reused in the same or other applications, where conventional borosilicate sight glass discs cannot.

L. J. Star also supplies light port glass discs for Lumiglas® light ports and custom sizes, including Borosilicate Glass to DIN 7080; Soda Lime Glass to DIN 8902; and Quartz Glass.

We also provide wipers for the manual cleaning of the inside glass surface of light ports and sight ports. Sight glass wiper blades are available in Teflon or Silicone, and are a great addition to when used in combination with a spray ring or spray nozzle.

Luminaire timers permit direct or indirect switching of an Ex or Non-Ex Light where observation is only occasional and brief. Illumination is limited to the required period, and luminaires are not left switched on unintentionally, reducing power consumption and heat build up, and increasing halogen lamp life.

The new TCI ClampConnect™ sanitary clamp virtually eliminates the dead space associated with a standard ferrule. This patent pending clamp design eliminates the need for tools by using a standard sanitary clamp and gasket for assembly. Unlike other designs, there are no acorn nuts or studs that can be lost or cross threaded.
