Texas Pressure sensors ala HopRodGarage

[brewslinger]

Howdy everyone,

I ended up ordering some pressure sensors like what HopRodGarage installed on his system and decided that they were not the route I wanted to go after all.

My loss is your gain.

The specs are:

Pressure range: 0 - 50 millibar (~20 inches of water)
Input voltage: 5v - 24v
Output voltage: 0 - 5v
Temperature rating: 212F with cooling tube section / 176F without
Sensor body connection: G1/2 (on sensor body)
Cooling tube connection: 1/4" NPT
Cable: 3 meters

The depth reading is easily read with a ADC that can handle a 5v input.

Would recommend installing them in a similar fashion to HopRodGarage's installation.
The following is what I was planning on doing.

Connecting to kettle:
- 1/2" NPT port on kettle

- 1/2" camlock male (type F - if female bulkhead / type A if male bulkhead)
- 1/2” camlock female (type D)
- 1/2" street 90
- 1/2" MNPT -> 1/4" FNPT bushing
- Cooling tube
- sensor

Price: $70 (including shipping in the USA)
I currently have 4 of these in hand.

HopRodGarage’s version: https://www.homebrewtalk.com/showpost.php?p=8090927&postcount=10

Note: Only the sensors are for sale. The camlock and other fittings are there to demonstrate a connection scheme.

Whats the idea with these - specific gravity from differential pressure, pressure monitoring during fermentation, or DIY spunding valve?

Edit: I'm dumb - you had the link in your post. Automated kettle filling. Really neat idea!

 

[brewslinger]

Yes that is correct. They are for measuring the amount of liquid in your vessels.
This info can be used to fill to a specific amount or to know when you have sparged enough for your preboil volume.
You could check your preboil and post boil volume as well.

All sorts of ways to leverage the data points.

Here is a copy of the specification sheet in case anyone is interested.

Do you happen to have these 2 left? If so how much?

 

[brewslinger]

Yes I do have them left. I'd like $140 including shipping in the US.
