Sanitary Union Sight Glass with Wired Light

Wired Flat Lamp & Union Seat Construction

This sanitary union sight glass assembly combines a weld-neck base ferrule, a circular viewing lens with elastomer sealing gaskets, a slotted round union nut, and a flat cabled luminaire attached to a side mounting bracket.

Unlike top-mounted cordless push lamps, this model routes an external electrical cable from the lamp housing and pivots on a side bracket lug, allowing the light unit to sit low across the viewing window without an internal wiper shaft.

Wetted Materials, Elastomers & Operating Scope

The series specification specifies SS304 and SS316L stainless steel, while the embedded parameter table also lists SS304L and SS316 alongside Silicone, EPDM, FKM (Viton), and NBR seal options.

General table parameters indicate an operating pressure range of 1 to 10 bar and a continuous working temperature of -20°C to +135°C with EPDM or Silicone seals.

Sight Glass With Lamp Drawing Dimensions

While Available in DN25–DN150 and 1"–6", the dedicated Sight Glass With Lamp drawing table provides envelope dimensions for four metric sizes from DN80 to DN150.

• DN80: Height H = 90.0 mm, outer diameter B = 127.0 mm, weld neck diameter D = 87.0 mm

• DN100: Height H = 100.0 mm, outer diameter B = 148.0 mm, weld neck diameter D = 106.0 mm

• DN125 & DN150: H = 90.0 to 96.0 mm, B = 178.0 to 210.0 mm, D = 132.0 to 157.0 mm

Power Supply & Specification Checks

The embedded series schedule reuses generic tubular sight glass text and does not state lamp supply voltage, wattage, or ingress protection rating. Confirm electrical specifications, cable gland rating, and exact weld-neck dimensions before ordering.
