Applications and Use Cases

The 190501-01-00-CN is ideal for monitoring vibration on pumps, motors, fans, compressors, and other rotating equipment. Its wide frequency response captures both low-speed and high-speed machinery vibrations, making it versatile across industries such as manufacturing, power generation, and oil and gas.

Because the transducer operates from -40°C to +85°C, it suits harsh environments, including outdoor installations and process areas with temperature extremes. The 100% condensing humidity limit ensures reliable performance in wet conditions, provided the unit is not submerged.

Installation and Setup

Mounting the 190501-01-00-CN is straightforward with the included stud option (3/8-in 24 to 3/8-in 24). Apply the recommended mounting torque of 4.5 N-m ± 0.6 N-m (40 in–lbf ± 5 in-lbf) to ensure proper coupling and accurate readings.

The MIL-C-5015 connection interface provides a secure, industrial-grade electrical connection. The transducer can be mounted in any orientation, giving you flexibility in tight spaces. For best results, follow the manufacturer's installation drawing and use the specified cable (part number 02173006) to maintain signal integrity over long distances.

Maintenance and Reliability

Regular inspection is key to long-term reliability. Periodically check the mounting torque and connector integrity, especially in high-vibration environments. The 316L stainless steel construction resists corrosion, reducing maintenance frequency.

Because the 190501-01-00-CN has no moving parts, it offers excellent long-term stability. Its temperature sensitivity variation of -8% to +5% typical over the operating range ensures consistent performance, helping you avoid false alarms and missed faults.

Compatibility and Integration

The 190501-01-00-CN is designed to work with Bently Nevada monitoring systems and other data acquisition equipment that accept velocity transducer inputs. The output bias voltage of 10.1 Vdc ± 1.0 Vdc is standard for many vibration monitoring systems.

For hazardous area installations, the 190501-01-00-CN offers intrinsic safety approvals (Ex ia IIC T4, AEx ia IIC T4) as per the agency approval options. However, the specific CN option indicates country-specific approval, so verify your area classification before ordering.
