Bently Nevada 350901-010 HTVAS Field Interconnect Cable

350901-010 Bently Nevada HTVAS Field Interconnect Cable

Product Introduction

The Bently Nevada 350901-010 is a robust and reliable interconnect cable specifically engineered for use with velocity sensors in critical machinery monitoring applications. As part of the 350900 series, this 10-foot (3.05-meter) cable ensures secure signal transmission from the sensor to the monitoring system. Its rugged construction, featuring a 300 series stainless steel overbraid and mineral insulation, provides exceptional durability and protection against mechanical stress and harsh environmental conditions. Furthermore, this cable supports a wide operating temperature range and is approved for use in hazardous locations, guaranteeing dependable performance where it matters most.

Technical Specifications

The 350901-010 delivers precise signal integrity with minimal interference. Its velocity output sensitivity is rated at 3.94 mV/mm/s (100 mV/in/s) ±5%. Additionally, the frequency response remains within ±5% from 40 Hz to 1 kHz (2400 cpm to 60 kcpm) and within ±3 dB from 25 Hz to 2 kHz (1500 cpm to 120 kcpm), both with a full 305-meter cable length.

Moreover, the cable's electrical characteristics include a quiescent current of 6 mA nominal with no load and an output bias voltage of -10.0 ± 2.0 Vdc. The transverse sensitivity is less than 5% of the axial sensitivity, and the amplitude linearity is ±1% up to 4900 m/s² (500 g) peak acceleration. The system also features a case-isolated grounding design to prevent ground loops.

Key Electrical Parameters at a Glance:

• Input Voltage: -18 to -30 Vdc (-18 to –28 Vdc for hazardous areas)

• Velocity Range: 1270 mm/s (50 in/s)

• Broadband Noise Floor: 0.05 mm/s rms (0.002 in/s rms) max from 5 Hz to 2 kHz

• Mounted Resonant Frequency: Greater than 15 kHz

Mechanical and Environmental Durability

This cable is built to withstand extreme conditions. Constructed from 300 series stainless steel with mineral insulation and a stainless steel overbraid, it resists abrasion, corrosion, and high temperatures. Specifically, the Bently Nevada 350901-010 maintains system sensitivity within ±10% when the sensor operates between -54°C and +399°C (-65°F to +750°F) and electronics between -54°C and +125°C. For even more demanding applications, it retains ±15% accuracy with sensor temperatures up to +482°C (+900°F). The cable diameter is 6.35 ± 1.27 mm (0.25 ± 0.05 in), and it has a minimum bend radius of 51 mm (2.0 in), allowing for flexible installation in tight spaces.

Hazardous Area Approvals

The 350901-010 is certified for use in potentially explosive atmospheres, providing versatility across various industries. Its approvals include:

• cNRTLus: Ex ia IIC T4/T492 °C Ga; Ex ia IIB T4/T492 °C Ga

• Class I, Zone 0: AEx ia IIC T4/T492 °C Ga; AEx ia IIB T4/T492 °C Ga

• Class I, Div. 1 & 2: Groups A, B, C, D; Class II & III, Div. 1

• Ex ec IIC T4/T492 °C Gc for Zone 2 applications

Consequently, this cable is suitable for a broad range of hazardous environments, from petrochemical plants to power generation facilities.

Installation Guidelines

Proper installation is crucial for optimal performance of the Bently Nevada HTVAS Field Interconnect Cable.

1. Cable Routing: First, plan the cable path to avoid sharp edges, excessive heat sources, and areas with high vibration that could exceed the 51 mm minimum bend radius.

2. Connection: Next, securely connect the integral cable to the sensor and the monitoring electronics. Ensure all connections are tight and properly sealed to prevent moisture ingress.

3. Grounding: Since the case is isolated, the system must be grounded according to the manufacturer's specifications to ensure safety and signal integrity.

4. Cable Length: Finally, be aware that the maximum cable length is 305 meters (1000 ft). Verify the total length does not exceed this limit to maintain signal integrity.
