FTQN-W3.0 Wireless Data Transmission Bridge Amplitude Detector

The FTQN-W3.0 Wireless Data Transmission Bridge Amplitude Detector enables real-time monitoring of mid-span bridge deflection, pier amplitude, acceleration, and train speed during train passages. The analysis software supports time-domain and frequency-domain waveform analysis, graphical and report display, and printing.

I. Instrument Principle

The device uses an 891-IV acceleration sensor to measure real-time bridge vibrations. The sensor transmits data wirelessly to the host unit, which then relays it to a computer via a USB port. Powered by a lithium battery, the sensor requires minimal cabling during on-site measurements, ensuring ease of use.

II. Main Technical Parameters:

1、Measurement range: 0–20.48 mm (single amplitude); 5–399 km/h.

2、Error ≤ 5% (calibration error on vibration table).

3、Test channels: 4 vibration channels, 1 speed channel.

4、Trigger method: Automatic.

5、Transmission and reception distance: < 2 km.

6、Operating conditions: Temperature -10°C to 55°C, humidity ≤ 95% RH.

7、Lithium battery: Continuous power supply ≥ 8 hours.
