PX26 SERIES Pressure Transducers INSTRUCTION SHEET M1608/1018 Shop online at: omega.com e-mail: email@example.com For latest product manuals: omegamanual.info GENERAL INFORMATION Omega’s Pressure sensors are four-active piezoresistive bridge devices. When pressure is applied, a different output voltage proportional to that pressure, is produced. Wet/Wet Differential Pressure Sensors simultaneously accept independent pressure sources. Gage Pressure Sensors provide a form of differential pressure measurement in which atmospheric pressure is used as a reference. The PX26 is available in variety of PSI ranges and as differential and gage sensors: MODEL NUMBER (GAGE) PX26-001GV PX26-005GV PX26-015GV PX26-030GV PX26-100GV PX26-250GV RANGE 0-1 PSIG 0-5 PSIG 0-10 PSIG 0-30 PSIG 0-100 PSIG 0-250 PSIG MODEL NUMBER (DIFFERENTIAL) PX26-001 DV PX26-005DV PX26-015DV PX26-030DV PX26-100DV PX26-250DV RANGE 0-1 PSID 0-5 PSID 0-15 PSID 0-30 PSID 0-100 PSID 0-250 PSID UNPACKING Remove the packing list and verify that all equipment has been received. If there are any questions about the shipment, please call Omega Customer Service Department at 1-800-622-2378 or 203-359-1600. We can also be reached on the Internet at omega.com e-mail: firstname.lastname@example.org Upon receipt of shipment, inspect the container and equipment for any signs of damage. Take particular note of any evidence of rough handling in transit. Immediately report any damage to the shipping agent. NOTE: The carrier will not honor any claims unless all shipping material is saved for their examination. After examining and removing contents, save packing material in event reshipment is necessary. MEDIA COMPATIBILITY Input media are limited to those media which will not attack polyester, flurosilicon, or silicon, such as oils, lacquer thinner, hydraulic fluid, most petroleum products, water and salt water. Not recommended for freons. SOLDERING Limit soldering temperature to 600°F (315°C) for 10 seconds duration maximum. ELECTRICAL CONNECTION NOTCHED (PIN 1) – + + METER – 1 2 3 4 WARNING! READ BEFORE INSTALLATION Fluid hammer and surges can destroy any pressure transducer and must always be avoided. A pressure snubber should be installed to eliminate the damaging hammer effects. Fluid hammer occurs when a liquid flow is suddenly stopped, as with quick closing solenoid valves. Surges occur when flow is suddenly begun, as when a pump is turned on at full power or a valve is quickly opened. Liquid surges are particularly damaging to transducers if pipe is original empty. To avoid damaging surges, fluid lines should remain full (if possible), puts should be up to power slowly, and valves opened slowly. To avoid damage from both fluid hammer and surges, a surge chamber should be installed, and a pressure snubber should be installed on every transducer. Symptoms of fluid hammer and surges damaging effects: a) Pressure transducer exhibits an output at zero pressure (large zero offset). If offset is less than 10% FS, user can usually re-zero meter, install proper snubber and continue monitoring pressures. b) Pressure transducer output remains constant regardless of pressure. c) In severe cases, there will be no output.
