Overview：
The Bently Nevada 177230-01-02-00 seismic-style transmitter is a loop-powered vibration transmitter from the 177230 series. It utilizes a piezoelectric accelerometer to measure vibration and outputs a standard 4–20 mA signal for monitoring the vibration status of machinery. The device can be mounted on bearing housings or equipment casings to collect vibration data, with readings transmitted directly to a PLC, DCS, or SCADA system.

Questions & Answers
💡 FAQ
Q: What is Bently Nevada 177230-01-02-00 used for?
A: It is a seismic transmitter that measures casing vibration on rotating equipment and sends 4-20 mA output to control systems for condition monitoring.
Q: What does each suffix in 177230-01-02-00 stand for?
A: The suffixes define measurement range, frequency response and certification settings. Each digit set changes the operating behaviour of the vibration transmitter.
Q: Can I replace 177230-01-02-00 with the base 177230 model?
A: No. The base part number does not lock in the range and frequency settings. Direct swap may produce incorrect vibration readings.
Q: What power supply does this seismic transmitter require?
A: It runs on 18 V DC to 30 V DC loop power. 24 V DC is the most common supply voltage in field installations.
Q:What are the available shipping methods?
A: FedEx, DHL, UPS, and others.
