OEM Sound Velocity Sensors

Valeport’s in-house design and manufacture capability mean we can provide customized OEM versions of our “time of flight” sound velocity technology.

These versions will suit less mainstream or emerging applications, or for integration into third party systems. The technology is already available in a number of standard instrument packages, which cater for the majority of applications requiring the ultimate in SV measurement. Please contact us to discuss your requirements.

Technical Specifications

Sensor Specification

Instantaneous response; the digital measurement is also entirely linear, giving predictable performance under all conditions.

Acoustic Frequency
2.5 MHz
Range:
1375 - 1900m/s
Resolution:
0.001m/s
Accuracy:
Dependent on sensor size
100mm
Random noise (point to point) ±0.002m/s
Max systematic calibration error ±0.013m/s
Max systematic clock error ±0.002m/s
Total max theoretical error ±0.017m/s
50mm
Total max theoretical error ±0.019m/s
25mm
Total max theoretical error ±0.020m/s
The accuracy figure quoted is a worst case scenario based on Total Error
Budget, as detailed above. Accuracy is independent of sample rate, since each
reading is derived from a single acoustic pulse. No RMS filtering or data
averaging is used to derive the quoted accuracy.

Data Output

Type:
RS232 & RS485 output, selected by command code
Baud Rate:
2400 - 115200
(NB. Low baud rates may limit data rate)
Protocol:
8 data bits, 1 stop bit, No parity, No flow control
Sample Rate:
1, 2, 4, 8, 16, 32 or 60Hz, or sample on demand
