WEMA Leakage Alarm
WEMA Leakage Alarm
The WEMA water level alarm gives you an acoustic warning when the water level rises above the normal level, e.g. in the bilge.The robust switch for the alarm is mounted in the bilge at a height where there is normally no water and connected to the buzzer included. If the water inside the sensor tube rises to 80 mm, the warning buzzer switches on.Jamming of the float by foreign objects is impossible due to the surrounding V4A tube. The switching unit can be easily pulled out of the holder and cleaned. The durable design also includes the encapsulated electronics and a 3 m long connection cable with a cable cross-section of 2 x 0.75mm².The switch can also be optionally connected to a signal lamp.The maximum load capacity is 0.3 amps at 12 volts and 0.15 amps at 24 volts.The water alarm is suitable for 12 and 24 volts.

WEMA GPS Speedometer analog/digital
WEMA GPS Speedometer analog/digital
GPS instruments with digital display of course (COG) and analog display of speed (SOG) over ground. A high-quality 32-channel receiver in combination with a separate antenna ensures good reception even in problematic installation conditions. The instruments are a very good alternative to conventional speedometers, since no hull penetration is required and no fouling influences the display. The installation diameter (85 mm) corresponds to that of the classic instruments, a change to new technology is therefore possible without any problems. The illumination color is adjustable in red/orange or yellow. Delivery includes waterproof, separate GPS antenna (45 x 40 x 15 mm) with 4.80 m cable. For power supply 12V.With the optional exchangeable front rings the design of the instruments can be adapted.
