The transducer uses a MIL-C-5015 connection interface and offers mounting hardware option 02 with stud 3/8-in 24 to 1/2-in 20. Agency approval option 01 includes CSA/NRTL/C (Class I, Division 1) and ATEX/IECEx/CSA (Class I, Zone 0/1) certifications.

Industry Applications

In petrochemical plants, the 190501-02-00-01 monitors vibration on critical pumps and compressors operating in hazardous areas. Its intrinsic safety approvals (Ex ia IIC T4, AEx ia IIC T4) allow installation in Class I, Division 1 environments without compromising safety. The transducer's wide frequency response captures both low-speed and high-speed machinery faults, from imbalance to bearing defects.

Power generation facilities benefit from the sensor's ability to operate continuously at temperatures up to +85°C, making it suitable for turbine bearing housings and generator end windings. The 316L stainless steel case resists corrosion in humid and chemically aggressive atmospheres.

For water and wastewater treatment, the transducer's 100% condensing humidity tolerance ensures reliable operation in wet environments. The internal electronics remain isolated from the case, preventing ground loops that can corrupt vibration signals.

Installation & Setup Guidance

Proper mounting is essential for accurate vibration measurement. The Bently Nevada 190501-02-00-01 accepts any orientation, simplifying installation on horizontal or vertical shafts. Use the specified mounting torque of 4.5 N-m ± 0.6 N-m to ensure consistent mechanical coupling without damaging the sensor threads.

Connect Pin A to the positive signal lead and Pin B to common. When velocity is from base to top of the transducer, Pin A goes positive with respect to Pin B, confirming correct polarity. Maximum cable length is 305 metres (1,000 ft.) using cable part number 02173006, with no signal degradation.

For hazardous area installations, follow drawing 167536 and observe temperature class T4 with ambient limits of -40°C to +100°C. The transducer's internal electronics are isolated from the case, eliminating the need for special grounding considerations in most installations.

Maintenance & Reliability

Routine inspection of the mounting surface and connector integrity ensures long-term reliability. The 316L stainless steel construction resists corrosion, but periodic checks for physical damage or loose connections help maintain measurement accuracy. No internal adjustments or calibration are required under normal operating conditions.

The transducer's transverse response is less than 5% of axial sensitivity, minimizing cross-axis errors that can mask true vibration levels. With a shock limit of 5000 g pk, the sensor withstands occasional mechanical shocks without damage.

Buying Guide

Before ordering the 190501-02-00-01, verify your required agency approvals and mounting hardware configuration. This unit ships with agency approval option 01 (CSA/NRTL/C, ATEX/IECEx/CSA) and mounting hardware option 02 (stud 3/8-in 24 to 1/2-in 20). Ensure your application's environmental limits fall within the -40°C to +85°C operating range.
