(if possible), pumps should be brought up to power slowly, and valves opened slowly. to avoid damage from both fluid hammer and surges, a surge chamber should be installed. symptoms of fluid hammer and surges dam- aging effects: ? digital gauge exhibits large zero offset. ? digital gauge pressure display remains constant regardless of pressure ? error code is displayed on screen. freezing: prohibit freezing of media in pressure port. unit should be drained. (mount in vertical po- sition to prevent possible overpressure damage from frozen media.) 3. installation: this procedure requires the use of a 1 1 M 16 ? (27mm) hex wrench for tightening the in- strument to the process connection. apply teflon tape or a suitable sealing compound to npt threads of the gauge. take using the wrench, tighten 1 turn beyond hand-tight or until a leak-proof seal has been achieved. caution: tightening the product by grasping or putting a tool on the plastic housing can cause permanent damage to the product. 5 warning! read before installation 1. general: a failure resulting in injury or damage may be caused by excessive overpressure, excessive vibration or pressure pulsation, excessive in- strument temperature, corrosion of the pres- sure containing parts, or other misuse. consult omega engineering before installing if there are any questions or concerns. 2. overpressure: pressure spikes in excess of the rated over- pressure capability of the gauge may cause irreversible electrical and/or mechanical damage to the pressure measuring and con- taining elements. 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. pressure surges: surges are particularly damaging to pressure gauges if the pipe is originally empty. to avoid pressure surges, fluid lines should remain full http://www..net/ datasheet pdf - http://www..net/
