Reflex and Transparent Flat Glass Gages – Pressures Up To 4000 PSI @ 100°F / 2775 PSI @ 600°F
Northeast Controls Models RH and TH are high pressure armored level gages engineered for demanding applications requiring elevated pressure ratings while maintaining accurate liquid level indication. Manufactured from solid bar stock with forged covers and precision-machined chambers, these gauges provide dependable service in high-pressure process systems.
Available in both single and multiple section types 1 through 9 with a one-piece liquid chamber. Machined from solid bar stock of cold rolled carbon steel, stress relieved and assembled complete with drop forged steel covers, tempered borosilicate glass, gaskets, bolts and nuts — making the gauges resistant to thermal shock, heat, corrosion and abrasion.
REFLEX GAUGES (Model RH) — Equipped with flat reflex glass comprising reflecting prisms that cause the liquid inside to appear black. The vapor space above appears silvery in direct contrast, assuring a distinct reading of the liquid level. No external illuminator required.
TRANSPARENT GAUGES (Model TH) — Equipped with two flat plain glass sections, one on either side of the liquid chamber, allowing light to pass through for clear observation of liquid level, color, interface layers, and product clarity. Plastic or MICA shields can be furnished for caustic or acid service. Supports external illuminators.
CONNECTION STYLES — Available with end, side, or back connections in 1/2" and 3/4" NPT. Offset close hook-up, union end connected, and standard close hook-up configurations also available.
OPTIONAL CONFIGURATIONS — Frost Proof models available for temperatures as low as -325°F (all stainless steel construction below -150°F). Heated/cooled models available for viscous liquids. Large chamber models (RHC/THC) available for surging or boiling liquids.
