Abstract
An apparatus for monitoring at least one physical or chemical process variable, comprising at least one measurement branch and a compensation branch connected in parallel therewith for compensating the influence of at least one environmental parameter on the process variable and/or on the measuring of the process variable. The measurement branch includes at least one primary sensor unit and a primary electronics unit for signal registration, evaluation, and/or feeding. The compensation branch includes at least a secondary sensor unit and a secondary electronics unit. The secondary sensor unit is so embodied that it registers a physical or chemical variable characteristic for the at least one environmental parameter, wherein the secondary electronics unit is so embodied that it draws the required energy from the measurement branch, and that it produces from the characteristic physical or chemical variable a compensation signal, which it transmits to the primary electronics unit of the measuring branch.
