DEVICE FOR MEASURING THE TEMPERATURE OF A MEDIUM THROUGH A WALL

摘要

A measuring device for determining the temperature of a medium in a container or a pipe has at least one temperature sensor, arranged on the outside of a container or pipe wall; an output for the temperature registered thereby; and an output for the measurement result obtained thereby. The device connects at least one first differentiator, capable of determining at least one first derivative of the progression over time of the temperature registered by the temperature sensor; at least one first multiplier for multiplying the derivative by a first factor which is a value for the time constant of the heat transfer through the wall; and;at least one adder,;between the output of the temperature sensor and the output of the measuring device.

1. A measuring device configured to determine a temperature of a medium in a container or pipe, the device comprising:
a measuring device output for a measurement result (TM); a temperature sensor, is arranged on an outside of a wall of the container or pipe; a temperature sensor output for a temperature (TF) registered by the temperature sensor; a first differentiator, capable of determining at least one first derivative of a progression over time of the temperature (TF), registered by the temperature sensor; a first multiplier configured to multiply the first derivative by a first factor (F1), the first factor (F1) being a value for a time constant of heat transfer through the wall; and an adder, wherein the first differentiator, the first multiplier, and the adder are connected between the temperature sensor output and the measuring device output, wherein a first adder input is connected to a first multiplier output, wherein a second adder input is connected to the temperature sensor output independently of the first adder input, and an adder output is connected to the measuring device output for the measurement result (TM).
