Product Description

The 41 X digital low pressure transducer incorporates a capacitive ceramic diaphragm specifically designed for measuring low pressures.  The capacitance sensing technology also offers a high overpressure rating to protect the pressure sensor from pressure surges which are much higher risk at low pressures.

For interfacing with your own digital network the 41X digital low pressure sensor has inbuilt fully configurable and addressable RS485 communication electronics which can be linked together with a number of other digital sensors.

For installations requiring a total solution for connecting to a PC computer there is a USB and RS232 data cable option which when used with the supplied software enables real time logging of the pressure and temperature readings plus the plotting of graphs and export of data files.
