Stuart Posted March 30, 2010 Share Posted March 30, 2010 My van has a Nordelettronica NE148-T control panel which includes an indicator for the outside temperature. The sensor dangles out of the bottom of the awning light fitting. The temperature reads 10 to 15 deg. higher than it should, it was ok but we noticed it had gone berserk one evening after the outside light had been on for 2/3 hours, presumably making the fitting hot. When the fitting had cooled off the temp still read way high. Q. Can the thing be re-calibrated or is the sensor "over the hill" and needs replacement.

flicka Posted March 31, 2010 Share Posted March 31, 2010 Hi Bakerboy Unable to offer much help, but firstly I would check the connection to the control panel. I would also put the question to dealer &/or manufacturer If the sensor has failed, I think you may have to go down that route anyway. Link to comment Share on other sites More sharing options...
Keithl Posted March 31, 2010 Share Posted March 31, 2010 Hi Stuart, From my experience with temperature measuring instrumentation used on our development cars at work I would imagine that the sensor is made up of a 2 core wire with cores of dis-similar metals and it measures the temperature at the point that the 2 are connected together. If the wires have shorted inside the light or at any other point then the temperature will be measured at that point. For example if that was inside the M/H then it will display the inside temperature. Check the wiring to the sensor very carefully for any signs of shorting or damage. Remember it is not ordinary wire so you will only be able to replace it with the correct part. Let us know how you get on. Keith. Link to comment Share on other sites More sharing options...
silverback Posted March 31, 2010 Share Posted March 31, 2010 hi ya not much more than has been said maybe google the part name? as on the panel, or motorhome manufacturer failing that go outside in the niff !! then you would know the temp!!

AliB Posted April 1, 2010 Share Posted April 1, 2010 I had a problem with a Nordelettronica charger a while back. Their office in Hull gave me the required information. http://www.yell.com/b/Nordelettronica+Europe+Ltd-Caravan+Repairs+and+Service-Hull-HU70WD-5968803/index.html Let us know the result.

Brambles Posted April 1, 2010 Share Posted April 1, 2010 Kieth, These sensors are not thermocouple type as you have described - they are temperature dependant resistors. They fail quite a lot if the moulding around the componet is not good or not impervious to moisture. You can check them using resitance measurent on a multimeter, but as you get different specs you need to know what the spec is. Agreed though check the connections to the control panel are sound and clean. Link to comment Share on other sites More sharing options...
Stuart Posted April 1, 2010 Author Share Posted April 1, 2010 Thanks for replies to date. I've checked and can find no loose or corroded connections. Tried to phone Nordelettronica in Hull but phone not working, will try after the weekend. Stuart Link to comment Share on other sites More sharing options...

Stuart Posted April 6, 2010 Author Share Posted April 6, 2010 As a finale to this one, I tried Nordelettronica at Hull again without success. It seems they have a UK agent, Delta whosay the Hull place has closed down,but they have no info on what is supplied to CI so suggested I contact a dealer. At this point I decided to investigate further and found by swopping inner and outer that the sensor is u/s . Have ordered new one at£30 + vat. Thanks to all for ionfo.
