SDT270 - Ultrasound Detector with Memory

Overview

The SDT270 is a digital ultrasound detector with data recording and spectral analysis capability. It helps control energy costs, predict failures, improve product quality and increase equipment uptime.

Key features

Data recording

• Internal memory — for measurement recordings
• SD card slot — memory expansion
• USB connection — data transfer to PC
• Export — to UAS3 software

Analysis

• FFT spectra — frequency analysis
• Time waveforms — oscillogram of the ultrasound signal
• Spectral comparison — against reference baselines
• Trends — tracking of changes

Applications

All 8 pillars of ultrasound testing:

1. Mechanical monitoring
2. Bearing lubrication
3. Compressed-air and gas leaks
4. Electrical defects
5. Steam traps
6. Hydraulic systems
7. Valves
8. Tightness testing

Advantages

Downtime prevention

• Early detection — before catastrophic failure
• Forecasting — estimating remaining equipment life
• Planned maintenance — repairs during a convenient window, no emergency shutdowns

Energy control

• Leaks — detection and assessment of losses
• Cost — calculation of energy losses
• Savings — cost reduction

Data management

• Database — all measurements stored
• History — tracking of changes
• Reports — professional documentation
