Transport shock according to DIN EN 60068-2-27 15 g / 11 ms / 3 axes
Pressure port 1) G1/4 threaded port according to DIN 3852 form E
Housing materials V4A (1.4404), PEI, HNBR
Material process interface with measuring cell 1.4542 (17-4 PH / 630); seal ring NBR
Throttle material 1.4305
Throttle element In the pressure channel of the process interface. It corresponds
to a nozzle of 0.3 mm and reduces the risk of damage during
highly dynamic effects such as pressure peaks or cavitation.
