2 Pressure decay sensor 00 % pneumatic Also available in ATEX version for use in potentially explosive atmospheres in accordance with 94/9/EC Directive Pressure decay sensor Operatin pressure 8 Flow at 6 s NI/min 00 Trippin point with 6 supply b 0. Connection Subbase pae 4 Operatin temperature C +0 operations Connections Without flow restrictor With flow restrictor Sinal when cylinder is in Sinal when cylinder is out Fitted inline between the cylinder and the control valve, the sensor will ive an output when the pressure in this line is exhausted and the cylinder is at end of stroke. For the correct usae of sensors on a fallin pressure, it is recoended that the practical cylinder load is limited to 60% of the theoretical force. Evolution of pressure within a doubleactin cylinder Pressure in the cylinder Circuit pressure Workin pressure Pressure difference Operation of the sensor on a fall in pressure Exhaust pressure Cylinder response time Control valve chaneover Cylinder travel time Startin point End of stroke of cylinder Time ATEX version products are available in the followin catoloues: Pneumatic products for explosive atmospheres or on our website
