High Temperature Accelerometersnnn288 ºC accelerometerElectrically ground isolated10/32 connector (side or top exit)These units are structured with a piezoelectric ceramic sensing element, operating in a shear mode geometry,for stable operation in the presence of thermal transients and base bending. Welded, hermetically sealed,titanium construction prevents any influx of dirt or moisture. Electrical ground isolation prevents ground loopproblems and noise pick-up from the surface of the monitored device.Since the output of these accelerometers is at a very high impedance, a high degree of insulation resistanceis required of the signal transmission path. Low noise cables are recommended for routine, high temperatureapplications and hardline cables are advised for radiation environments. The use of an in-line charge converteris recommended to convert the measurement signal to a lowimpedancevoltage for long distance transmission.Technical SpecificationsHigh Temperature ChargeOutput AccelerometerModel 357B53n Sensitivity: (±15%) 100 pC/gn Measurement Range: ±150 g pkn Frequency Range: (±5%) 3 kHzn Electrical Connector: 10-32 coaxial jackProduct shown at actual size1.13 1.13in(28.6 (28.6) mm)13/16 Hex10-32ConnectorLock Wire HoleLock (2 Places) Wire Hole(2 places)10-32 Mtg Mounting Hole HoleHigh Temperature ChargeOutput AccelerometerModel 357B54n Sensitivity: (±15%) 100 pC/gn Measurement Range: ±150 g pkn Frequency Range: (±5%) 3 kHzn Electrical Connector: 10-32 coaxial jackProduct shown at actual size1.44(36.6)10-32Connector13/16 Hex HexLock Wire Hole(2 places) Places)10-32 Mtg Mounting Hole HoleModel Number 357B53 357B54Performance100 pC/gSensitivity (± 15 %)10.2 pC/(m/s²)± 150 g pkMeasurement Range± 1,470 m/s² pkFrequency Range (+5 %) 3 kHz [2]Frequency Range (+10 %) 3.5 kHz [2]Frequency Range (+3 dB) 5.5 kHz [2]Resonant Frequency≥ 12 kHzNon-linearity ≤ 1 % [3]Transverse Sensitivity ≤ 5 %Environmental± 2,000 g pkOverload Limit (Shock)± 19,600 m/s² pk-100 ºF to 550 ºFTemperature Range-73 ºC to 288 ºC0.0002 g/µεBase Strain Sensitivity0.002 (m/s²)/µε [1]Radiation Exposure Limit≤ 10(Integrated Gamma Flux)8 radRadiation Exposure Limit≤ 10(Integrated Neutron Flux)10 N/cm²ElectricalCapacitance 930 pF [1]Insulation Resistance≥ 10(at 550°F)8 ohm [1]Insulation Resistance≥ 10(at 70° F [21°C])12 ohmOutput PolarityNegativeElectrical Isolation (Base)≥ 10 8 ohmPhysicalSensing ElementCeramicSensing GeometryShearHousing MaterialTitaniumSealingHermetic3/4 in x 1.13 in 3/4 in x 1.43 inSize (Hex x Height)3/4 in x 28.7 mm 3/4 in x 36.3 mm1.80 ozWeight51 gm [1]Electrical Connector10-32 Coaxial Jack (side)Mounting Thread10-32 FemaleSupplied AccessoriesModel 081B05 Mounting Stud(10-32 to 10-32) (1)Model ACS-1 NIST traceable frequencyresponse (10 Hz to upper 5% point).

For 288 ºC to 650 ºCoperating environments, PCB ® offers a range of both singleended output (measurement output as a signal and ground)and differential output (measurement output as a plus andminus signal) sensors. The former tend to be smaller andmore suitable for short term testing needs, while the latterare more appropriate for long term monitoring applications.Obviously, the environments in which these sensors operateare challenging. In fact, in some of the highest temperatureoperating environments, the operating sensor measuresvibration signatures while glowing red hot.

Such circumstances place extremedemands on vibration sensors and require use of accelerometerswith special design characteristics that extend their useabletemperature range beyond that of other conventional units. Forthese demanding situations, IMI Sensors offers two styles ofhigh temperature industrial vibration sensors.A variety of ICP ® piezoelectric industrial accelerometers areavailable with high temperature “HT” option, which extendstheir usable range to 163 ˚C. This option replaces their standard,internal signal conditioning circuitry with circuitry specificallydesigned and tested to reliably withstand elevated temperatures.These accelerometers, though equipped with the “HT” option,will operate in the same manner and with the same cable, datacollection and signal conditioning equipment as standard, ICP ®industrial accelerometers.For extreme, high temperature requirements, charge outputaccelerometers are recommended. Designed to withstandtemperatures to 649 ˚C, charge output accelerometers donot contain internal signal conditioning circuits which imposetemperature limits on standard piezoelectric ICP ® accelerometers.However, since there is no signal conditioning circuitry withincharge output accelerometers, alternative cable and signalconditioning equipment are required. To simplify installation ofthese sensors, IMI Sensors offers complete kits that include thenecessary low noise cable and in-line charge converter to adapta charge output accelerometer to conventional ICP ® sensorsignal conditioners and data collection equipment.
