FURUNO 50BL-24HR Transducer
A BLT transducer (Bolt-clamp Langevin Transducer) 50BL-24HR has replaced the
50F-24H or 50BL-24H in FCV-291/292/1100L/1200L/1500 and ETR-2D/30N.
The BLT transducer has large bandwidth, good sound efficiency, compact
structure and is reinforced for protection against slamming.
WARNING: Turn off the power at the switchboard before beginning the
installation.
Fire or electrical shock can result if the power is left on.
- Be sure no water leaks in at the trans-ducer mounting location.
- Water leakage can sink the vessel. Also, confirm that the transducer will not loosen by ship’s vibration.
- The installer of the equipment is solely responsible for the proper installation of the equipment. FURUNO will assume no responsibility for any damage associated with improper installation.
CAUTION: Do not install the BLT transducer where noise or air bubbles is
present.
Performance will be affected. The BLT transducer cable must he handled
carefully, following the guidelines below.
- Keep fuels and oils away from the cable.
- Locate the cable where it will not be damaged.
- The cable sheath is made of chloro- phrene or polychloride vinyl, which are easily by damaged plastic solvents such as toulene. Locate the cable well away from plastic solvents.
- Do not lift the BLT transducer by its cable. Wires of the BLT transducer may be cut.
Features
When the BLT transducer is connected to the FCV-1100L or FCV-1200L,
sensitivity is sufficient even if the frequency is shifted ±10% to suppress
interference.
The BLT transducer can be installed in tank for the transducers shown in the
table below.
BLT transducer| Transducer previously used| Output| Note on replacement of
transducer
---|---|---|---
50BL-24HR| 50F-24H| 3 kW| Shorten the length of
spacers.
50BL-24H| Change fixing flange for transducer.
Add spacers.
Installation
Install the BLT transducer referring to its outline drawing and tank drawings.
Setting the echo sounder
Set the supply voltage or tap on the echo sounder referring to the
installation manual.
| Name | Supply voltage |
|---|---|
| FCV-1200L | 90 |
| FCV-1500 | 90 |
| Name | Tap |
| --- | --- |
| FCV-1100L | E |
| FCV-291/292 | E |
| ETR-3D | No change |
| ETR-30N | E |
Note
38 k type transducer and 50 k type transducer share the same dimensions. To
distinguish them, the SC lock of 38 k transducer is gray and that of the 50 k
transducer is black.
