Thank you for the design ideas! A question: have you experienced positive pore pressures on your tensiometers? If yes, is the rubber stopper vulnerable to eject?

Thanks Stephen for your question. No we have not had enough positive pressure in the tensiometer to eject the stopper. They sometimes get knocked out by workers are tractors passing by.

I'm struggling to find the ceramic cup that you have mentioned on the vendor's website. Should I just email them? Also, is there any particular reason why you chose that vacuum gauge? You can purchase vacuum gauges with identical specs and design but with a plastic housing instead of stainless steel for half the price on zoro and other sites. Just curious if you have had bad experiences with the plastic backed gauges. Thanks

Hi Ben,  
 
The new ceramic cup that glues onto PVC from soil moisture corp. has to be custom-made in small batches--not yet a big seller. If you have trouble ordering it, I suggest that you call Alan Farad directly at 805-964-3525 ext 223

Hello,  
Is there any other source for the ceramic cups? Soilmoisture has been less than cooperative in offering these for sale. They accepted the order but I have been waiting weeks and am unable to get any kind of response or order update from them.  
Thanks!

Hi Evan,  
 
Sorry that soilmoisture is taking so long to send you the cups. I do not know of a substitute source. I suggest that you call Alan Farad directly at 805-964-3525 ext 223

I contacted Alan at the Soil Moisture Equipment company since several readers mentioned that they cannot order the ceramic cup in a timely manner. This is the reply that I received from Alan which explains why the orders may take a few weeks:  
 
I do not think there is any particular issue with ordering the item (2630C). The lead time has recently been a little longer than usual. There reason was that I demanded to test each and every unit before shipping out to make sure that they perform well. Fortunately, the result was great (100% of the cups has passed the test so far). That is why we went back to the regular QC procedure. That will speed up the manufacturing process in the future.  
 
One other thing worth mentioning is that we usually build to order. That is why our standard shipping lead time is 14 to 45 days (we usually ship in 2 weeks). Many people are surprised when they find out that they need to wait several days for their order to ship. That is because we are manufacturer, not retailer. We often times do not have 100s of the item in stock.  
 
Regarding the 2630C, at the moment we have about 60 in stock. In case the orders pick up, we make more and we stock more.  
 
In case somebody would like to order, they can email orders@soilmoisture.com or call (805964-3525 X240).  
 
If there is any particular issue, please have them contact me directly. I’ll do my best to help.  
 
Please let me know if you had any questions.  
 
With kind regards,

Hi,  
 
An alternative to the cup availability problem would be the Blumat cups out of Austria. They are available in North America fir a reasonable price. In use them in my home tensiometer with good results and 80kPa are achievable. Please refer also to the Martin Thalheimer article in my previous post.  
 
Regards,  
Gerhard
