Abstract

The present disclosure relates to an in-line compact measuring device, for example for optical measurements, comprising a housing having a process connection intended to be connected to a process vessel connection complementary to the process connection; at least one sensor assembly arranged in the housing; and a measuring circuit that is connected to the sensor assembly and is arranged in the housing. The in-line compact measuring device has at least one fluid line in thermally conductive contact with at least one housing wall of the housing, which fluid line can be connected to a cooling fluid supply arranged outside the housing.

First claim

The invention claimed is:

1. An in-line compact measuring device, comprising:
a housing having:
a front end and a rear end, wherein the housing is embodied cylindrically about an imaginary Z-axis extending from the front end to the rear end;
a process connection disposed toward the front end and embodied to attach the in-line compact measuring device to a complementary process connection; and
an electronics compartment disposed at the rear end and extending from the rear end toward the process connection, wherein the electronics compartment has a cylindrical side wall;

a sensor assembly arranged in the housing;
a measuring circuit connected to the sensor assembly and arranged in the electronics compartment of the housing;
a cylindrical metal cooling plate disposed within the electronics compartment about the imaginary Z-axis and running along the side wall of the electronics compartment; and
a fluid channel integrated into a wall of the housing and arranged between the process connection and the electronics compartment, wherein the fluid channel includes an inlet opening and an outlet opening in the wall of the housing enabling the fluid channel to be connected to a cooling fluid supply arranged outside the housing.

2. The in-line compact measuring device according to claim 1 ,
wherein the sensor assembly includes a radiation source arranged in the housing and a radiation receiver arranged in the housing, and
wherein the radiation source and the radiation receiver are connected to the measuring circuit.

3. The in-line compact measuring device according to claim 2 , further comprising:
at least one measurement window integrated in a wall of the housing.

4. The in-line compact measuring device according to claim 1 ,
wherein the electronics compartment is sealed tightly against the environment.

5. The in-line compact measuring device according to claim 1 ,
wherein the cooling plate is formed from copper, silver, gold, or aluminum.

6. The in-line compact measuring device according to claim 1 ,
wherein the cooling plate is in thermally conductive contact with the fluid channel.

7. The in-line compact measuring device according to claim 1 , wherein the fluid channel runs annularly about the imaginary Z-axis of the housing.
