HPT 500 was specially developed to provide a cost-efficient solution for the measurement of differential pressure. A piston movement inside of the device is evaluated by means of a Hall sensor, which enables to determine the occurring differential pressure and makes available an analogue output signal for the integration into a controller. The particularity about this measuring principle is that even with high pressures, e.g. in a 350 bar system, high-precision measurement of very low differential pressures (i.e. < 2 bar) is possible.
The differential pressure transmitters with the ignition protection type "flameproof enclosure" combine ATEX, IECEx and CCSAUS approval for the North American market. This allows universal world wide use of the sensor in potentially explosive atmospheres.HPT_500_PressTrans.jpg
