Abstract
A leakage sensor for a heating unit of an absorption cooling device for a recreational vehicle, a heating unit, an absorption cooling device, a vehicle and a method for operating an absorption cooling device are provided. The leakage sensor uses sensor pins to detect cooling fluid leaking from the boiler of the heating unit of the absorption cooling device into the boiler insulation by measuring the electrical resistance and/or conductivity within the boiler insulation.
