The 177230-01-02-CN is a high-precision, loop-powered seismic vibration transmitter designed to provide a 4-20 mA output proportional to vibration velocity. This 177230-01-02-CN unit is an essential component for monitoring the casing vibration of industrial machinery such as electric motors, centrifugal pumps, and medium-speed fans in the oil and gas, power generation, and mining sectors. By allowing for direct integration into a PLC or DCS without the need for an intermediate monitoring rack, this transmitter offers a cost-effective solution for asset protection. Its robust 316L stainless steel construction ensures reliable performance in corrosive and high-humidity environments, enabling early detection of mechanical imbalances and bearing wear to prevent catastrophic equipment failure.
The technical profile of the 177230-01-02-CN is defined by the following suffix configurations:
177230: Base model for the Seismic Vibration Transmitter series.
-01 (Measurement Range): Calibrated for a velocity range of 0 to 25.4 mm/s (0 to 1.0 in/s) peak.
-02 (Frequency Response): Provides a wide frequency bandwidth from 3 Hz to 1 kHz (180 to 60 kcps) peak, suitable for a broad spectrum of rotating machinery.
-CN (Agency Approvals): Mandatory China-specific approvals. This version is fully certified by NEPSI and meets CCC (China Compulsory Certificate) requirements for explosion-proof safety according to the GB 3836 standard, authorizing its use in hazardous industrial zones within the Chinese market.
| Attribute | Specification Details |
| Model | 177230-01-02-CN |
| Brand | Bently Nevada (Baker Hughes) |
| Origin | U.S.A. |
| Output Signal | 4-20 mA DC (Proportional to Velocity) |
| Case Material | 316L Stainless Steel |
| Connector Type | 3-pin MIL-C-5015 (316L SS) |
| Mounting Hole | 1/4-28 UNF |
| Operating Temp | -40 to +85 deg C |
| Relative Humidity | Up to 100% non-submerged |
| Dimensions | 25.4 mm (Diameter) x 66.0 mm (Height) |
| Net Weight | 0.131 kg |
How does the -CN version differ from the standard international model?
The 177230-01-02-CN is functionally identical to the standard model but includes the specific firmware and labeling required for NEPSI/CCC compliance. This is a legal requirement for any explosion-proof equipment being installed in regulated facilities across China.
Is this transmitter compatible with standard PLC inputs?
Yes. Since the transmitter provides a standard 4-20 mA loop-powered signal, it can be wired directly into any PLC or DCS analog input card that supports a 2-wire or 4-wire loop configuration.
What is the maximum humidity this unit can withstand?
The transmitter is rated for up to 100% relative humidity, provided it is not fully submerged. The 316L stainless steel case and connector ensure that moisture does not lead to casing corrosion or signal degradation.
Mounting Surface and Torque Requirements
For accurate seismic measurement, the transmitter must be rigidly attached to the machine casing. The mounting surface should be flat and free of debris. Use the 1/4-28 UNF mounting hole to secure the device. We recommend a mounting torque of 2.7 to 6.8 Nm (24 to 60 in-lb). Ensure the transmitter is oriented in the specific axis (horizontal, vertical, or axial) you intend to monitor.
Wiring and Loop Power Considerations
The 177230-01-02-CN is a 2-wire, loop-powered device typically requiring a supply voltage between 12 and 30 VDC. Use high-quality shielded twisted-pair cabling for the signal loop. The shield should be grounded only at the control system end to prevent ground loops, which can introduce noise into the 4-20 mA signal.
Hazardous Area Compliance
To maintain the NEPSI/CCC safety rating in hazardous environments, the transmitter must be installed in conjunction with an appropriately rated intrinsic safety (IS) barrier. Ensure that all conduit and cable entries meet the local GB 3836 explosion-proof requirements to ensure the overall integrity of the safety loop.
