Quick Detail

Description

The 177230-01-01-CN Seismic Transmitter is a sophisticated, loop-powered vibration sensing solution designed by Bently Nevada to provide continuous machinery protection. As a robust and reliable 177230-01-01-CN Seismic Transmitter, this device integrates a high-precision piezo-velocity sensor with a 4 to 20 mA signal conditioner into a single, compact housing. The 177230-01-01-CN Seismic Transmitter is specifically engineered to interface directly with Programmable Logic Controllers (PLCs) or Distributed Control Systems (DCS), making it an essential component for modern industrial asset management.

By utilizing the 177230-01-01-CN Seismic Transmitter, plant operators can monitor the casing vibration of rotating machinery without the need for a separate monitoring rack. This 177230-01-01-CN Seismic Transmitter features a velocity-based measurement range of 0 to 25.4 mm/s (0 to 1.0 in/s) peak, which is the industry standard for assessing the mechanical health of pumps, motors, and fans. The 177230-01-01-CN Seismic Transmitter is constructed from 316L stainless steel, ensuring it remains impervious to corrosive environments and extreme industrial conditions.

A key advantage of the 177230-01-01-CN Seismic Transmitter is its "CN" designation, which indicates compliance and documentation suitable for the Chinese market and international hazardous area standards. With a frequency response range of 10 Hz to 1,000 Hz, the 177230-01-01-CN Seismic Transmitter effectively captures the most common machine faults, such as unbalance, misalignment, and looseness.

Applications

The 177230-01-01-CN is widely applied in the continuous monitoring of general-purpose rotating machinery, such as industrial motors, centrifugal pumps, and small blowers. By mounting the transmitter directly onto the bearing housing, it converts mechanical casing vibration into a standard 4-20 mA analog signal. This allows plant engineers to track vibration trends directly on their control room HMI, enabling early detection of mechanical degradation before it leads to unplanned production stops.

In the power generation and HVAC sectors, this seismic transmitter is utilized to monitor cooling tower fans and large air handling units. Its 316L stainless steel housing and wide operating temperature range (-40°C to +85°C) make it ideal for these outdoor and high-humidity environments. The 10 Hz to 1,000 Hz filter range is specifically tuned to ignore low-frequency structural sway while accurately capturing the rotational vibration frequencies that indicate motor or gearbox wear.

For hazardous area applications in refineries and chemical processing plants, the 177230-01-01-CN provides a safe and certified monitoring solution. With its multiple approvals (CSA, ATEX, IECEx), it can be installed on reciprocating compressors or agitators in explosive atmospheres. The transmitter’s electrical isolation and low transverse sensitivity ensure that the vibration data remains accurate and free from cross-axis interference, even when surrounded by heavy electrical equipment and complex piping systems.

Specifications

Competitive Advantage

Integrated 4-20 mA Signal Conditioning The 177230-01-01-CN eliminates the need for external charge amplifiers or dedicated vibration monitors. By providing a direct loop-powered 4-20 mA output, it simplifies the system architecture and significantly reduces installation costs. This "all-in-one" design allows users to leverage their existing PLC/DCS infrastructure for sophisticated machinery protection.

Rapid Response and Settling Time Unlike many seismic sensors that require long stabilization periods, this transmitter features a settling time of less than 15 seconds. This ensures that accurate vibration data is available almost immediately after a machine starts up or after a power cycle. This fast response is crucial for protection logic where immediate and reliable data is required to prevent damage during transient machine states.

Exceptional Environmental Durability The use of 316L stainless steel for the case and a hermetically sealed design provides superior protection against moisture, chemicals, and salt spray. Combined with a mounted resonant frequency of greater than 12 kHz and high electrical isolation, the transmitter offers long-term stability and resistance to signal noise, ensuring a low total cost of ownership in the harshest industrial climates.
