Enabling the Extraordinary To Fly To Rower To Live MEGGHT Piezoelectric dynamic pressure sensor MAIN KEYWAY Key features • +986°F (+530°C) operation; +1040°F (+560°C) intermittent operation • Small dynamic pressure measurements even under high static pressure • Balanced differential output • Hermetically sealed • Integral hardline cable • All Inconel and stainless steel construction INCHES (MILLIMETERS] Meggitt model 522M37A is a high quality piezoelectric pressure sensor designed to measure small dynamic pressure fluctuations, even in the presence of high static pressure. The sensor can also operate at very high temperatures; up to +938°F continuously and up to +1040°F intermittently. Model 522M37A features an all welded, Inconel and stainless steel construction with a metal-sheathed, mineral-insulated integral hardline cable. Output is via an integral three-pin (one pin not used) receptacle. The output signal is a balanced, differential signal. A differential input charge amplifier is appropriate for use with this sensor. Common applications include: gas turbine combustion monitoring, high pressure steam and propulsion system testing. Recommended compatible cables are the 6917M169-ZZZ, 6917M170-ZZZ and 6917M171-ZZZ or equivalent (ZZZ designates cable length in inches) which are low noise, twisted pair cable assemblies terminating to pigtail, BNC and PC06A-8-2P connector respectively.

MEGGHT Piezoelectric dynamic pressure sensor Specifications The following performance specifications conform to ISA-RP-37.2 and are typical values, referenced at +75°F (+24°C), 4 mA, and 100 Hz, unless otherwise noted. Calibration data, traceable to National Institute of Standards and Technology (NIST), is supplied.

Piezoelectric dynamic pressure sensor 1. Intermittent temperature exposure is defined as 5 minutes over a 30 minute period. 2. For short cable lengths, provision must be made to ensure receptacle is not exposed to temperatures greater than +500°F (+260°C). Minimum cable length is 12 inches. Cable length “ZZZ”is in inches and is determined by model dash number, i.e. 522M37A120 has a cable length of 120 inches. 522M37A – ZZZ Integral hardline cable length in inches Basic Model Number Continued product improvement necessitates that Meggitt reserve the right to modify these specifications...
