Furuno 295 temp problems nmea 0183

[Jnr6.1]

Hi the temp on my unit jumps up and down about 1 deg C and I think it’s a problem in my unit as I have tried 2 temp sensors on the 6pin pig tail. Can I connect through the nmea 0183 ports ? If so what sensor would I need to get ?

Thanks Paul.

Airmar sells an analog to NMEA temp converter that can be used to bring in temp into sounders by NMEA format. After making the change, you would need to change the temp source in the menu.

Many transducer temp sensors are not that precise unless you have one labeled "High Precision Temp" from Airmar. They tend to get cracked and broken internally in the pounding of waves particularly as they age. You could be right that the change is due to the sounder but it could also be from a temp sensor that is cracked or just not that precise. You might first connect the temp wires (disconnected from the sounder) to a meter and check the resistance. If the resistance is constantly changing then the odds of it being due to the sensor is high. The process of the temp translates to temp based on resistance. If the resistance is solid so should be the temp.

Hi Johnny

Will I have to get a different sensor or will it still work running through analog. I have a airmar tm185hw with temp in it or a airmar
T-04mtb sensor? Both are brand new.

Either sensor can be used with an analog to NMEA converter. Both the transducer temp and the T-04 are analog. The T04 is a much better temp sensor than what they put into transducers if it is working.

I just looked it up and I found one that suits my plotter I’m thinking I could link my plotter to the 295 with this and use the 1870 for the temp sensor. Have you got any information on how I would wire this (pictured) to the 295 ?

The IF-NMEA2k2 is a NMEA 2000 to 0183 (and vice versa) converter. I won't accept analog temp. You might be thinking of the IF-NMEAFI device. It can function as a temp converter but out of the box is defaulted as a Tank Sensor. It is a good device but you would need to order one pre-configured for "Temp" or have a NavNet TZT2/3 display, FI70 or Navpilot 300 to be able to change the MODE to temp, unless you ensure you order it pre-configured. Then it would be pretty simple wiring. In your case it would be just a two wire splice connection for the temp wires.

Ok I will keep it simple I will order the IF-NMEAFI as I only really need the temp working properly cheers for the info.
