Specifications:
The HL98 level indicator is designed to operate at a maximum working pressure of 1 bar (14.5 psi). It features external protection made of anodized aluminum, reinforced nylon terminals, a transparent polyamide central body, and a polyamide float. Fixing screws and nuts are made of zinc-plated steel, while seals are available in Buna and Viton materials. The working temperature range for Buna seals is -30 to 90 °C (-22 to 195 °F) and for Viton seals is -20 to 110 °C (-4 to 230 °F).

Fluid Compatibility:
The indicator is compatible with various fluids, including mineral oils (HH, HL, HM, HR, HV, HG) with Buna seals, and synthetic fluids (HS, HFDR, HFDU, HFDS) with Viton seals. It also supports water emulsions (HFAE, HFAS) with Buna seals.

Technical Features:
The HL98 includes a visual level indicator and a normally closed (N.C.) electrical contact that activates when the float reaches the minimum level. It is designed for high impact resistance and features external protection in anodized aluminum.

Dimensions:
The HL98 level indicator is available in two types: HL98-20 and HL98-30. The HL98-20 weighs 0.17 kg (0.37 lb) with dimensions of 170 mm (6.8 in) in length, while the HL98-30 weighs 0.21 kg (0.46 lb) with a length of 294 mm (11.76 in). Both types have a width of 20.5 mm (0.82 in).
