Elesa+Ganter HRT.20-32 Oil Level Indicator
The Elesa+Ganter HRT.20-32 oil level indicator is a push-fit fluid level sight glass developed for industrial reservoirs and machine lubrication systems. It provides a simple but highly practical way to monitor oil level directly through the tank wall, helping maintenance teams make faster and better-informed service decisions.
Built for Clear Level Reading
One of the strongest features of the HRT.20-32 is its readable visual layout. The unit combines a transparent polyamide window with a white lacquered aluminium contrast screen and a red level line. This makes the fluid level easier to identify during routine checks, even in environments where lighting conditions are not ideal.
The body itself is made from black polyamide-based technopolymer with a matte finish. That combination gives the product a balance of light weight, durability, and industrial-grade appearance.
Technical Features of the HRT.20-32
The Elesa+Ganter HRT.20-32 oil level indicator is intended for push-fit installation and uses optimized ribbing to support secure assembly. Sealing is provided by an NBR synthetic rubber O-ring, which is a key factor in maintaining dependable performance on reservoirs with limited pressure.
For this specific size, the catalog values include a 32 mm reference dimension, A 10.5, B 4.5, D 36, inner reading-related reference d 18, minimum wall-related dimension Smin 8, and a 32 mm mounting hole reference. The maximum continuous working temperature is 100°C.
Why This Size Is Popular
The HRT.20-32 offers a useful middle ground in the product family. It is larger than the most compact option, which can improve visibility, but it still remains easy to integrate into many reservoir designs. For that reason, it is often chosen for general industrial machinery, hydraulic units, process equipment, and lubrication circuits where engineers want a practical visual check point without taking up unnecessary space.
In service environments, clear level monitoring reduces guesswork. That can help prevent underfilling, overfilling, and avoidable downtime caused by delayed fluid checks.
Application Perspective
The Elesa+Ganter HRT.20-32 oil level indicator is well suited for oil tanks, gearbox lubrication housings, hydraulic power packs, and compact industrial reservoirs. It supports maintenance planning by making fluid condition checks part of a simple visual routine.

FAQ
What is the main purpose of the Elesa+Ganter HRT.20-32 oil level indicator?
Its purpose is to provide a direct visual reading of fluid level in a reservoir or machine tank without opening the system.
What kind of mounting does the HRT.20-32 use?
It uses a push-fit design. The ribbed outer form supports secure positioning, while the O-ring helps create the seal.
Why is the contrast screen important?
The contrast screen improves readability by creating a clearer visual background for the fluid level and red indicator line.
Can the HRT.20-32 be used in industrial hydraulic systems?
Yes. It is particularly appropriate for hydraulic reservoirs and similar systems operating with limited pressure where visual level monitoring is needed.
What is the continuous working temperature limit?
The maximum continuous working temperature listed for the HRT product family is 100°C.
