We now have an oil level switch for heat pumps and similar applications called HBSO-MT. The switch is suited for applications where the oil temperature is between 40°C and 90°C (104°F and 194°F). The product is physically similar to HBSO, but it has a different switch point which comply to increased oil temperatures and the increased pressure. Read more about the sensors for heat pumps.
