I couldn't believe it either. I'm attributing it to the fact that I had such a low temp mash and added 2lb of brown sugar to the boil. I did an actual attenuation measurement (not apparent) and it came out to 74%, which is right between 73 and 77 stated by wyeast (I'm using American Ale 1056...

Well, thanks for knocking some sense into me. I haven't had time to take an gravity reading until tonight. I'm sitting at 1.004 (to be expected since I mashed at such a low temp). Really wanted to be at 1.017 per the recipe. Definitely didn't underpitch... Should I rack to a secondary now...

Did an all grain Pumpkin Ale this weekend. It was my first 10 gallon brew, and I didn't hit my mash temps (was at 146F for most of it). Anyway, I just doubled a 5 gallon recipe. OG was 1.060. I used 2 Wyeast 1056 American Ale packs for the 10 gallons (no starter). Fermentation really took...

Just go the new SSR this afternoon. Works like a champ! I'll be brewing a pumpkin ale tomorrow. I went with the 40A one instead of the 60A. I couldn't find a datasheet for the 60A anywhere online, which makes me wonder if they stopped making them or if it was a counterfeit part. Either way...

I'm not taking my volt meter between the output and return, I'm taking it across the SSR and across the heating element. The more I think about it, the more I am thinking the SSR is bad. When I have no load attached to the output of the SSR, the voltage dropped across the SSR is in the mV...

I will give the light bulbs a try. The leakage would explain it working under no load. Still doesn't explain why I see all the voltage dropped across the SSR and not the heating element when the led on the SSR is lit up, right?

Yep, LED flashes on/off. I can see the 12V from the PID toggling at the correct duty cycle with a volt meter. I'll try a 9V battery and see what happens. edit:9V battery gives same result. bad SSR maybe?

As requested (note, no neutral coming over, just 2 hots and an earth ground, on a 30A breaker):

I've been lurking around here for quite a while now, and I rarely post. I decided to go to electric brewing. I am having problems getting the SSR to switch (at least I think...) My setup is a basic as it gets: 240VAC in Auber PID controller powered of 240VAC Fotek SSR-60DA SSR L6-30R plugs...

if you're seeing that much movement, then the sensor is bad or it is picking up a bunch of noise. Physically moving the wire doesnt induce any more or less electric field. Moving it towards a noise source does. Using twisted shielded cable will certainly help with any noise. You could also...

Hopefully I can be of some help, I'm an electrical engineer. Length of cable shouldn't be a problem unless you are pulling a lot of current through it. Do you have a schematic of what the sensor excitation (power source) and sensor output look like? Really need to know what the output of the...
