Google Patents US7798017B2 - Ram pressure probe having two ducts and a differential pressure increasing element Valve does not hold in “retract” position.US7798017B2 - Ram pressure probe having two ducts and a differential pressure increasing element The opposite happens when solenoid “B” is energized. Solenoid is energized to position “A,” oil port “A” becomes pressurized to extend cylinder piston. Operation with double-acting cylinder: Port “A” is connected to “advance” port of cylinder, oil port “B” connects to cylinder “return” port. Sequence: When energized to position “A,” oil port “A” becomes pressurized and clamps the fixture connected to oil port “A” oil port “B” becomes a “return” port for cylinder connected to oil port “B,” and retracts it. Operation with multiple single-acting cylinders: A pressure line from one bank can be connected to oil port “A” and the other to oil port “B” on the valve. When solenoid is energized to position “B,” oil port “A” becomes the return port. With port “B” plugged, solenoid is energized to position “A,” oil port “A” becomes pressurized. Operation with single-acting cylinder: Either oil port “A” or “B” must be plugged on valve. View Catalog - Gauges - US ‖ UK ‖ DE ‖ ES ‖ FR Agency Compliance / Approval: RoHS, CE, ASME B40.7, UL, cUL 61010-1.Includes automatic-off battery conservation, pressure tare, minimum pressure memory and maximum pressure.Five pre-programmed engineering units allow technicians to read pressure in the unit of measure most applicable to the process.The laser welded stainless steel sensor & socket and the IP67 weatherproof rating make this product suitable for use in the most demanding of applications.Digital gauge is easier to read and offers better accuracy than a conventional analog gauge.Operating temperature of 0 to 140☏ for the electronic display and -20 to 180☏ for the transducer.ĩ042DG & 9042DG1500 Digital Pressure Gauges.Fast blinking display alerts if limit is exceeded. A slow flashing display indicates pressure below the low limit."Peak" hold feature with reset toggle switch and "Peak On" indicator Hi/Low set point feature with relay outputs for Hi/Low alarms and/or control signals. ![]() When power cable is connected to gauge, display will scroll all characters, performing a self-diagnostic routine. Pressure values are displayed on large red LEDs in 10 psi or bar increments.Accurate to within 1%, Long-life pressure transducer.Gauges are calibrated and comply to ASME B40.1 Grade B.4" and 6" (101,6 mm and 152,4 mm) dry gauges can be filled with silicone (Kit #9046).Stainless steel cases and lens locking rings.High strength steel bourdon tube ensures high cycle life.Gauges feature an easily readable and highly visible, red Day-glo® needle.
