Auxiliary device for measuring pressure and/or temperature at devices and when installed (in operation). This is only possible if some thought has already been paid during the planning stage for a system as to where measurements will subsequently need to be taken for inspection purposes.
The mini measuring device (for on-line operation) consists of a measuring coupling attached to a device or fitting and which enables it to record measured variables via suitable ports (Figure M 25). To make it easier to use, the measuring device required is accommodated inside a measuring case.
