Need a manifold pressure transducer

[PhredPhantom]

Anybody know where to get a manifold pressure transducer for a 2000 Ovation 2?  I'm in negotiations (to buy) with the owner of the plane that needs one and he is just finishing the annual but is not able to find a replacement transducer for the manifold pressure gauge.  From what he's told me, this transducer supplies a signal to both the standard ("steam") gauge as well as the electronic manifold pressure indicator.  He says that since the Mooney plant is currently out of production, there is no source for this item.  I wonder if there is another source or if another transducer can be substituted and be legal.  

 

Any help would be appreciated.

 

Thanks,

Sounds like a trust issue...

The plant is running on all cylinders. The MSC system is the center of all spare parts support, since the 50's.

Go to the factory website. Look up MSC nearest you. Call with your question.

Sort of how I would do it,

Definitely call and MSC... might be one on the shelf somewhere.  They ain't cheap for the Ovations from what I've heard.  For long-term planning you might consider a modern engine monitor that can replace OEM instruments.  Sometimes one of these OEM transducers will cost nearly as much as a complete monitor system.

I assume that you have the moritz gauges. I had the same problem last year. Mooney makes a kit with a new style transducer for the maniford pressure. It was expensive like $500. I got the kit directly from Mooney.

THe transducer is the new kit is an Omegadyne. Go to Omegadyne.com

I just want to say Thanks to you guys for responding to my question about the manifold pressure gauge transducer.  I have sent a link to this thread to the broker who is handling the sale; I don't have the owner's email address.  

 

The broker tells me that they have decided to send the original transducer out to a repair shop.  I hope this works.  If not, I hope that they will decide to pursue some of your suggestions.  Since I am not currently the owner, I don't have control over what their decision turns out to be.

 

Thanks again for your good comments.

If it's the Moritz gauges you may also contact a member on here named Cris. He had dealt with Moritz on something a while back and may be able to offer some direction. I can't remember what but I remember speaking with him about Moritz.

I seem to have a similar issue in a 2003 M20R I'm working on.  The MP reads around 3.0" with the master on, but engine stopped.  The gauge does move with changes in pressure applied to the manifold line, but not to a reading that one would expect.  (from -6.0 to +5.5)  Also- when the transducer gets unplugged from it's cannon plug, the gauge skyrockets- up to over 100"...  That being said, I'm thinking that it's the pressure transducer, but not 100% sure that it's not the gauge, either.  

 

This part is no longer stocked- anywhere, it appears- and to order it from Mooney requires 90 days lead time and $2500.  The original part is an Ametek, p/n SP100-110-25A.  The new part number from Mooney has been changed to SP100-110-106A.  I've got an AOG, and need a better solution if anyone can help.

 

The Omegadyne kit as mentioned previously in this thread is unknown to Mooney-  

 

If anyone has any insight, it would be much appreciated.

I'd recommend a modern primary replacement engine monitor...just get rid of those expensive gauges that aren't really supported any longer.

OK.  The problem was fixed before I bought the airplane.  I'm not sure exactly which transducer they used but apparently it is one that you can buy now, although not cheap - about $1,200 from what the owner told me.  The problem was that the replacement transducer (I believe the correct part number was given above [sP-100-110-25A] but here was the problem.  The Mooney factory told the previous owner's mechanic that the replacement transducer would work but 2 of the 4 wires should be switched (and they told him which ones).  He did that and it didn't work so they sent the whole set of gauges and the transducer back to the Mooney factory and asked them to fix it.  Then they had to wait a week while the Mooney factory had their test equipment recertified because they hadn't done so while the factory was shut down.  When they finally got their equipment certified, they decided that the 2 wires didn't need to be switched after all and apparently everything worked just fine.  This was an ordeal that delayed my purchase of the airplane for a little over a month but now it has all been done and the plane is in my hangar.  I'm a happy camnper.

Glad it worked out and you got the plane!  Time for some pics now.

When I had my Ovation's manifold pressure transducer go inop, I contacted Mooney and bought a kit which included drawings and an Omegadyne transducer and connector. It was easy to change out the bad transducer for the new one. The drawings included how to calibrate the gauge.

I'm curious why someone said Mooney never heard of this kit.

Cost $4000 for transducer.  Will replace Moritz gauges.   Yes $4000

@M20R Hey M20R. Are you still active on here? My buddy’s M20S has the same issue, need a replacement pressure transducer. You have any information on this Mooney kit?

He was around here earlier in the day… today…

Hasn’t posted anything in a while…

But, he will get a notification that you are looking for him…

Just realize this thread is nearly a decade old…

Several years ago I purchased the kit from Mooney. It came with blue prints and all the connectors and transducer. The transducer for manifold pressure is an Omegadyne PX329-030AV. The transducer can be purchased for about $300.

Attached are some photos of the blueprints

@1966 M20C Driver your ship has sailed in!

See details from MSer M20R above!

Go MS!
