In a method for determining alignment of line formations of a web, a radiation source emitting radiation and a detector with numerous radiation sensors for sensing the radiation are provided. The radiation source and the detector are reciprocated together simultaneously transversely across the web. During reciprocation across the web, at least one measuring location of the web is irradiated by the radiation source and measured values, based on local radiation intensities are measured by the radiation sensors of the detector. The measured values are communicated to a computer. The computer generates, based on the measured values and the relative positions of the radiation sensors to one another, a local structural image of the at least one measuring location of the web.

Method and device for determining the alignment of line formations in areal, especially longitudinally moved, webs of a structural formed body

Sensor for radiation pyrometric temperature measurement at high ambient

Enthalpy quantities such as the degree of moisture of gases, the wetness of steam or the enthalpy of dry steam are measured by passing a specific amount or dosage of a gas or steam through a system such as a cooler or dryer wherein its thermal condition is changed while measuring the inlet and outlet temperature, and measuring heat radiated into the condition changing system whereupon the desired enthalpy quantity is obtained from a heat balance equation set up from the measured and known data.

Apparatus for determining enthalpy of a fluid medium

A thermal measurement of mass flow is obtained by passing a flowing mass through a hollow passageway, measuring the temperature of the mass at the inlet and at the outlet of said passageway and additionally measuring the heat flow released or absorbed through the walls of the passageway and then determining the mass flow by setting up the heat balance equation on the basis of the obtained data. Preferably, the data are fed into a computer to solve the resulting heat balance equation. The invention also comprises an apparatus wherein temperature sensors are arranged at both ends of a tubular passageway and wherein the heat flow meter comprises concentric wire coils of a thermic resistance material wound around the outer periphery of the tube and an interposed layer of predetermined thickness formed of a material of at most moderate heat conductivity.
