3500/94M 120M8155-01 Bently Nevada 10-Inch VGA Touch Screen Monitor

Product Overview

The 3500/94M 120M8155-01 is a high-performance visualization terminal designed to bridge the gap between complex machinery diagnostics and frontline operations. This 10-inch Advantech display utilizes a high-contrast LCD with LED backlighting, ensuring that critical vibration levels and system alarms are clearly visible even in varied lighting. Its design allows for multiple mounting configurations—including face, rack, and panel mount—providing flexibility for both cabinet-integrated and standalone monitoring stations.

Core Technical Advantages

1. Advanced GFG Resistive Touch Technology

The screen utilizes Glass-Film-Glass (GFG) resistive technology, which offers superior durability compared to standard plastic touch screens. This industrial-hardened surface is resistant to chemical exposure, moisture, and scratching, and it remains fully operational when used with heavy-duty industrial gloves.

2. Comprehensive Hazardous Area Compliance

Safety is paramount in oil, gas, and chemical processing. This unit is fully certified for hazardous locations, meeting ATEX/IECEx Zone 2 standards and North American Class I, Div 2 (Groups A, B, C, D) requirements. The IP54-rated housing ensures protection against dust ingress and water spray, maintaining operational integrity in volatile environments.

3. Extended Operating Temperature Range

Engineered for the extremes, the 120M8155-01 operates reliably in temperatures as low as -20°C (-4°F) and as high as 65°C (149°F). This thermal resilience allows for installation in remote instrument enclosures and facilities across diverse geographic climates without sacrificing performance.

Technical Specifications

Installation Considerations

• Mounting: Supports Face Mount, 19" Rack Mount, and Panel Mount. Please note that mounting screws are not included with this specific part number.
• Thermal Management: If the unit is expected to be exposed to temperatures below -20°C (-4°F), a heated enclosure must be utilized to prevent hardware damage.
• Panel Cutout: For panel mount installations, the required cutout dimensions are 342.9 mm (13.5 in) x 228.6 mm (9.0 in).

Technical FAQs

Q1: What is the benefit of the LED backlight on this model?

A1: LED backlighting provides consistent brightness across a wide temperature range, uses significantly less power than CCFL displays, and offers a longer operational life in continuous industrial use.

Q2: Does this unit include a power supply?

A2: Yes, a 24 Vdc power supply is included with the 120M8155-01. The unit can operate on a permissible voltage range between 10 Vdc and 28 Vdc.

Q3: Is the touch interface sensitive enough for industrial environments?

A3: Absolutely. The GFG (Glass-Film-Glass) resistive technology is specifically chosen for industrial settings because it relies on pressure rather than electrical conductivity, making it reliable for use with gloves and in dusty or oily conditions.
