When installing, ensure the sensor is mounted to a clean, flat surface to optimize frequency response and prevent resonance artifacts. For proximity-based monitoring systems, verify gap voltage validation (-10 VDC targets) if the accelerometer output is being compared against displacement data for correlated rotor dynamics analysis. The stainless steel, hermetically sealed housing serves as an EMI shield, providing cross-talk suppression by minimizing the impact of radiated electrical noise on the low-level signal conditioning circuit. During calibration, confirm the transducer sensitivity against the 100 mV\/g baseline to ensure accurate integration of acceleration data into velocity or displacement units within the 3500 rack.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 169337 accelerometer be used in conjunction with Bently Nevada proximity probes for X-Y shaft analysis?\u003c\/p\u003e\n\u003cp\u003eA: Yes. While proximity probes provide radial shaft displacement data, the 169337 accelerometer offers complementary data on high-frequency casing vibration, which is essential for comprehensive diagnostic coverage of turbine and compressor assemblies.\u003c\/p\u003e\n\u003cp\u003eQ: What are the requirements for the constant current excitation (2–20 mA) when using the accelerometer?\u003c\/p\u003e\n\u003cp\u003eA: The accelerometer requires a regulated constant current source within the specified range to power the internal signal conditioning amplifier. If the loop current is too low, the signal will clip; if too high, the internal circuitry may overheat.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Use a stainless steel mounting stud to fasten the 169337 accelerometer directly to the machinery case. Avoid using magnetic bases for permanent installations, as they introduce non-linear resonant behavior.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCabling:\u003c\/strong\u003e Utilize shielded, twisted-pair cabling for the accelerometer loop. Terminate the shield at the 3500 I\/O module end only to prevent ground loops that could introduce DC bias into the vibration signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Supply Setup:\u003c\/strong\u003e For the power supply variant, verify that the input AC supply voltage matches the configured internal transformer taps.
