Pressure Measurement
MC6-T supports the use of external pressure modules, EXT, when
they are connected to MC6-T's PX connector. MC6-T also includes an
optional internal Barometric Module for measuring barometric pressure
and together with a gauge EXT module, MC6-T indicates the absolute
pressure of any pressure the EXT module is capable of measuring.

cable (PX).
Note: The pressure measurement requires knowledge of
pressure types (absolute pressure, gauge pressure and
differential pressure). Measuring pressure with inadequate
knowledge of pressure types and the dangers of pressure
devices may result in false measurement results and/or serious
accidents. Please read the warnings in chapter MC6-T Safety.
Connecting and Disconnecting External Pressure Modules
When an external pressure measurement module is connected and when
applicable, MC6-T opens a dialog. Among other information, the dialog
includes a possibility to choose where to use the connected external
pressure module.
An external pressure module may be disconnected at any time. MC6-T
indicates that an external pressure module was removed. If the module
was used for a measurement, the measurement stops.
Warning: Select a pressure module that has a suitable
measurement range for your pressure signal. Too low/high
measurement range on the pressure module results in faulty
modules, imprecise readings or even accidents.
