1. A probe for sensing a physical quantity, comprising:a process connection; a metal rod having a first end connected to said process connection; a first gasket provided between said process connection and said metal rod forming a seal between said metal rod and said process connection; and a cylinder, located between said process connection and said metal rod, wherein: said cylinder is surrounded by said first gasket; and said first gasket defines a minimal distance between said process connection and said metal rod, the minimal distance ensuring a defined compression force exerted on said first gasket. 2. The probe according to claim 1, further comprising:a metal tip connected to a second end of said metal rod; a sheath covering said metal rod; and a second gasket provided between said metal rod and said metal tip which forms a seal between said metal rod and said sheath by abutting on a front surface of said sheath and an adjacent front surface of said metal rod facing towards said metal tip, wherein: said first gasket forms a seal between said sheath and said metal rod by abutting on a front surface of said sheath and an adjacent front surface of said metal rod facing towards said process connection. 3. The probe according to claim 2, wherein:said sheath consists of a plastic with a chemical resistance, in particular of polytetraflourethylen (PTFA) or perfluoroalkoxy (PFA). 4. The probe according to claim 2, wherein:said metal tip comprises an extension with a smaller diameter than the remainder of said metal tip, extending through said second gasket into said metal rod. 5. The probe according to claim 4, wherein:said metal tip extension comprises a thread and is screwed into said metal rod. 6. The probe according to claim 2, wherein:said metal rod comprises an extension that extends through said second gasket and is screwed into an axial bore in said metal tip. 7. The probe according to claim 2, wherein:a cylinder located between said metal tip and said metal rod, in particular a mid section of said metal tip or a section of said metal tip, said cylinder being surrounded by said second gasket, and wherein: said second gasket defines a minimal distance between said process connection and said metal tip; and the minimum distance insuring a defined compression force exerted on said second gasket. 8. The probe according to claim 1, wherein:said metal rod comprises an extension with a smaller diameter than the remainder of said metal rod, extending through said first gasket and said cylinder into said process connection. 9. The probe according to claim 8, wherein:said metal rod extension comprises a thread and is screwed into said process connection. 10. A measurement device for monitoring one or more predetermined levels (L1, L2, L3) comprising a probe for every predetermined level (L1, L2, L3) to be monitored, each probe comprising:a process connection; a metal rod having a first end connected to said process connection; a first gasket provided between said process connection and said metal rod forming a seal between said metal rod and said process connection; and a cylinder, located between said process connection and said metal rod, wherein: said cylinder is surrounded by said first gasket; and said first gasket defines a minimal distance between said process connection and said metal rod, the minimal distance ensuring a defined compression force exerted on said first gasket.
