Product overview
Combined Metal-Crank Wiper and Upright Lamp Construction
This sight glass integrates two vessel-observation accessories onto a union-retained circular sight port: a manual wiper driven by a central metallic crank handle, and an upright cylindrical wireless lamp on a side bracket. Rotating the crank sweeps the internal blade across the inner glass face to clear condensation or splash without opening the vessel.
Distinction from Lever-Wiper and Wiperless Union Sight Glasses
Within the union sight glass family, this configuration is distinguished by its bent metal crank arm and upright cordless lamp barrel, whereas sibling union sight glass options use either a black polymer lever handle with a slim tube lamp or an un-wiped lens assembly. The weld-in base neck is offered in SS304 and SS316L.
Base Port Reference Dimensions and Drawing Scope
The page embeds the base port reference drawing (DN65 to DN150 with neck OD D from 70 to 154 mm and neck height from 31 to 45 mm; 2.5" to 6" with D from 63.5 to 152.4 mm). Because the base port reference depicts the wireless-light base port without the crank wiper, it serves only as a base port reference and does not establish crank swing radius.
Operating Limits and Installation Checks
Available in vacuum to 10 bar and a temperature range of -10°C to 150°C for the port (-10°C to 80°C with lighting). Confirm the wiper blade elastomer, shaft seal material, and rotational clearance between the crank knob and side lamp.
