AP3500T2-Z1
Bently Nevada Case Mounted Accelerometer
Product Overview
The AP3500T2-Z1 is a case mounted accelerometer from Bently Nevada. It delivers 500 mV/g sensitivity with ±5% accuracy at 25°C. The unit measures up to 10 g peak with amplitude nonlinearity of 1%. Frequency response is ±10% from 0.4 to 1000 Hz and ±3 dB from 0.2 to 2300 Hz. Resonant frequency is 15 kHz. The accelerometer uses PZT ceramic shear sensing element with 316L stainless steel case. Hermetic sealing ensures reliable operation in harsh environments. Operating range spans -50°C to 120°C.

Oiltech Controls’s Insight
The AP3500T2-Z1 is a proven solution for bearing housing vibration monitoring. The 500 mV/g sensitivity provides strong signal output for long cable runs up to 100 feet. We recommend using shielded twisted pair cable to minimize EMI pickup. The 316L stainless case offers excellent corrosion resistance for marine and chemical environments. For installations above 120°C, consider alternative high-temperature models. Always verify bias voltage (10 Vdc) during commissioning. The case isolated design eliminates ground loop issues common in industrial settings.

Frequently Asked Questions
- Can the AP3500T2-Z1 be used with Bently Nevada 3500 monitors?
Yes, the AP3500T2-Z1 is fully compatible with Bently Nevada 3500 system accelerometer inputs. Verify monitor configuration matches 500 mV/g sensitivity. - What is the maximum cable length for this accelerometer?
Recommended cable length is 100 feet maximum. Longer runs may degrade signal quality due to capacitance effects. Use low-noise coaxial or twisted pair cables. - How do I verify proper operation after installation?
Measure bias voltage at 10 Vdc between Pin A and Pin B. Apply a known vibration source and check output signal. Compare sensitivity against specification using a reference vibration standard. - Can this unit be used in hazardous locations?
Standard AP3500T2-Z1 is not intrinsically safe. Contact our technical team for ATEX or IECEx certified versions if required for explosive atmospheres. - What is the difference between top exit and side exit connectors?
Top exit connectors (MIL-C-5015 style) allow easier installation in tight spaces. Side exit versions are available but may require special ordering. Confirm connector orientation matches your existing installation.
