Abstract:
1. A hand-guided work apparatus comprising: a combustion engine having a crankcase defining a crankcase interior; a crankshaft rotatably mounted about a rotational axis in said crankcase; a pressure sensor and a temperature sensor; a sensor housing common to both of said sensors; said temperature sensor and said pressure sensor being arranged in said sensor housing; said work apparatus being configured to have a set-down position wherein said work apparatus is placeable on a horizontal rest surface; said pressure sensor and said temperature sensor being beneath a plane containing said rotational axis and said plane being parallel to said rest surface when said work apparatus is in said set-down position; said sensor housing defining a connecting channel for causing said pressure sensor to communicate with said crankcase interior; said connecting channel having a base which slopes down toward said crankcase interior when said work apparatus is in said set-down position on said rest surface; a board held in said sensor housing; and, said pressure sensor and said temperature sensor both being arranged on said board; wherein said pressure sensor, said temperature sensor and said board are potted in said sensor housing.
