摘要： PURPOSE: To measure the dew point accurately even on a contaminated sensor surface regardless of the type and extent of contamination by compensating for the action of contamination automatically. CONSTITUTION: A measurement detector 10 comprising a sensor element 12 fixed onto a Pettier effect element 14 and a temperature sensor 16 is arranged in a process. A humidity signal from the sensor element 12 forms a sensor capacity signal through an impedance evaluation circuit 20 while a temperature signal from the temperature sensor 16 forms the surface temperature signal of the sensor element 12 through a temperature evaluation circuit 22 and both signals are fed to a microcomputer 30. The microcomputer 30 compares the sensor temperature with a target temperature and delivers a temperature control signal to the Peltier effect element 14 thus keeping the sensor temperature constantly at a dew point. According to a program routine presented at a function block 38 of the microcomputer 30, a capacity being used as a guide amount for temperature regulation is regulated automatically to match the sensor capacity at the dew point accurately and contamination of the sensor is compensated automatically.

摘要： A microwave antenna having an exponentially expanding horn of circular outlet cross-section. The inlet opening to the horn has a rectangular cross-section. In a transition region from the inlet opening up to the point at which the circular horn cross-section circumscribes the rectangular cross-section, each cross-section of the horn corresponds to the combination of the exponentially expanding circular cross-section and the rectangular cross-section.
