177230-00-01-CN | Bently Nevada Seismic Transmitter 0-12.7 mm/s

Reliable Vibration Monitoring with the 177230-00-01-CN

When unplanned downtime threatens production, the 177230-00-01-CN from Bently Nevada provides the early warning you need. This seismic transmitter converts vibration into a standard 4-20 mA signal, making it easy to integrate with existing PLC, DCS, or SCADA systems. With a measurement range of 0 to 12.7 mm/s (0 to 0.5 in/s) and a frequency response of 10 Hz to 1 kHz, it captures the critical vibration data that helps you detect issues before they become failures.

Built for harsh industrial environments, this transmitter features a 316L stainless steel case and connector, ensuring long-term durability. Its compact design—25.4 mm diameter and 66.0 mm height—allows for easy installation in tight spaces. Whether you are monitoring pumps, fans, or motors, the 177230-00-01-CN delivers the accuracy and reliability you expect from Bently Nevada.

Key Features and Technical Specifications

The 177230-00-01-CN is engineered for precision and robustness. Here are the essential specifications you can rely on:

• Measurement Range: 0 to 12.7 mm/s (0 to 0.5 in/s) ±10%
• Frequency Response: 10 Hz to 1 kHz (600 to 60 kcpm) ±10%
• Output Signal: 4-20 mA current loop (proportional to RMS vibration)
• Excitation Voltage: 12 to 30 Vdc (current limited to 40 mA)
• Operating Temperature: -40°C to +85°C (-40°F to +185°F)
• Case Material: 316L stainless steel
• Connector: 3-pin MIL-C-5015, 316L stainless steel
• Mounting Hole: 1/4-28 UNF
• Weight: 131 g (4.62 oz)

One standout feature is the mounted resonant frequency greater than 12 kHz, which minimizes the risk of resonance-induced errors in your measurements. Additionally, the transmitter is hermetically sealed and can operate in up to 100% relative humidity (non-submerged), making it suitable for damp or washdown environments.

Applications and Use Cases

This seismic transmitter is ideal for continuous vibration monitoring on rotating equipment such as motors, pumps, compressors, and fans. By providing a real-time 4-20 mA signal, it enables predictive maintenance strategies that reduce downtime and extend machinery life. For example, in a chemical plant, the 177230-00-01-CN can alert operators to bearing wear before catastrophic failure occurs, saving thousands in repair costs. Its compatibility with PLCs, DCS, and SCADA systems means you can easily incorporate it into your existing automation architecture.

Installation and Setup

Installing the 177230-00-01-CN is straightforward. The mounting hole is 1/4-28 UNF, and mounting threads include M6 x 1 SI, M8 x 1.25 SI, and 1/4-28 UNF. Recommended mounting torque is 4 to 7 N-m (35.4 to 62.0 in-lbf). The 3-pin MIL-C-5015 connector simplifies wiring: Pin A is the 4-20 mA positive loop, Pin B is the loop return, and Pin C provides a dynamic acceleration signal. Ensure the excitation voltage is within 12 to 30 Vdc and that the power supply is current-limited to 40 mA. For best results, mount the transmitter securely to a flat surface to avoid measurement errors.

Maintenance and Reliability

Routine maintenance is minimal thanks to the rugged construction and hermetic sealing of the 177230-00-01-CN. Periodically inspect the connector and cable for damage, and verify that the mounting remains tight. Because the transmitter is designed for long service life, you can expect consistent performance over many years. The stainless steel case resists corrosion, and the ceramic/shear sensing element provides stable output. To ensure accuracy, recalibrate the loop as part of your regular preventive maintenance schedule.

Compatibility and Integration

The 177230-00-01-CN is designed for seamless integration with industrial control systems. Its 4-20 mA output is universally accepted by PLCs, DCS, and SCADA systems. The dynamic acceleration signal on Pin C can be used for additional diagnostics if your system supports it. No special software is required—just connect the loop and configure your input channel. This makes the transmitter a flexible choice for both new installations and retrofits.
