Threaded or smooth casing
The CMA sensor assembly serie offers a very versatile range of pakaged pressure sensors designed for
measuring dynamic pressure either in air, water, steam.
The sensor assemblies consist of absolute or relative pressure die mounted onto smooth or threaded
casings. The sensors are coated with hydrophobic RTV ensuring their operation in water and steam. The
pakaged sensors are available for the most stringent applications requiering either high pressure
sensitivity or operation up to 220°C.
The sensors can be either operated in a constant current or constant voltage mode, and can be interfaced
on any standard signal conditionning and monitoring systems. The sensors are delivered fully calibrated
with integrated temperature compensation, if requested.

Options:
− The sensors can be ordered with LSc’s wireless data aquisition system (please refer to: wireless multisensor measurement system productsheet). The sensors will be delivered calibrated with the on-board
electronics, and a set of polinomial calibration coefficient will be provided to be used with LSc’s
monitoring software.
− The sensors can be ordered with integrated temperature compensation
− The sensors assemblies can be delivered with a perforated cover onto the sensor membrane for
operation in harsh environment
