Doppler Speed Log Simulator & Transducer Tester SIM999
Product Description
SIM999 can be used for testing single axis and dual-axis doppler speed log only.
As a doppler speed log simulator, it can be used for most of doppler speed log whose CentFreq is 1000kHz-2000kHz.
But it can’t be used for triple-axis doppler speed log.
Here below please refer tothe Simulator Setting of some models:
Simulator Set | DS80（JAPAN Furuno） | JLN-205（JAPAN JRC） |
CentFreq | 1000 kHz | 2000 kHz |
OutDepth | 2 m | 0 m |
OutWidth | 20 ms | 20 ms |
OutAngle | 37 Deg | 20 Deg |
As a doppler speed log transducer tester, it can measure the parameter of transducer. (Singleaxis or dual-axis only)
Here below please refer to the standard test data for some models.
Transducer Model | Speed Log Model | Manufacturer | Frequency | Resonant Impedance |
NKF-547 | JLN-205 | JRC | 2000 kHz | 40±20 ohm |
DS-820 | DS80 | FURUNO | 1000 kHz | 70±30 ohm |
If the transducer is damaged, usually the Resonant Impedance data tested will be very big.
For other transducers, we suggest test one new good transducer firstly to get the standard data.
For connection, usually, speed log has 2 signal cables for each direction.
Single axis: FORE/ AFT
Double axis : FORE/ AFT/ Port/ Starboard
As a Simulator for Double axis speed log, test FORE/AFT firstly, then Port/ Starboard
Transducer tester:
SIM999 can only test one direction everytime. fgtrw
