Just to close the loop on this, I was able to pull the center pin out with just my hands and a little movement. The pin and the head had formed enough rust to allow play. The pump head unit is 3 years old...I'll give it that. It has also had 5 runs through it and was always cleaned and dried...

I spent all day trying to figure out what's going on. Replacing the Spike sensors with class A sensors from Auber cut the fluctuations in half but they're still there. Even putting in a resistor allows the temperature to fluctuate 0.3 degrees over a given time period. The Auber sensors...

That's a great idea that my PLC programmer already incororporated. I'll attach the file in case anyone wants to take a look. Basically, we average out the readings over 5-10 samples and then push that to the PIC and on the screen. The massive temperature swings are just not able to be...

I tried Spike, Auber, some cheap option from Amazon and a very expensive probe from a commercial application. UPDATED: These sensors reported zero delta because they were not wired correctly. The wire outputs are different than every other sensor so the values were not valid...

I see that could be a concern so I turned the pump off and let it sit for 5 minutes. I did expect it to drop given it was hotter than room temperature. The problem was that it was jumping all over the place so heat layers wouldn't really explain the problem. I have new sensors on order so I'll...

Fortunately, it's a very easy process. 1.) Remove the pum head from the pump body by removing the TC clamp. 2.) Remove the motor bracket from the pump motor....4 phillips head screws. 3.) Inside the Motor bracket, you will find the cup magnet that's held on the shaft by a set screw...remove...

I 100% agree with you that nothing is perfect and mass produced items all have that inherent risk! That’s not what this is about. It’s the lack of customer care over a clearly defective pump. Telling a customer that they don’t see a problem and refusing to offer a solution is horrible customer...

The measurement is in a 20 gallon hlt brought to 180F with 15 gallons of water and then let alone with the pump flowing for a few minutes so the temp settles out. The measurement was taken from the plc pins and then the end of the cable attached to the probe and finally the probe itself. The...

Thank you very much for sharing this information. I have a spike pump as well and given this Blichmann pump failed, I’ll probably buy another spike pump. Blichmann knows there was a problem and is not being honest with their customers. You don’t make a design change because it’s fun, you do it...

Am I the only one really disappointed in Blichmann’s customer service and concern for quality? I have a pump with less than 5 batches of use. Given it’s more than a year old but it’s well cared for and low hours. The first problem was the bearings in the main body began to make a grinding...

I purchased two of them. One standard length and one with a 6" probe as I'm trying to get more accurate temperatures from my Spike HERMS system. It's a seperate issue but even with the pump running, the center is 4F higher than the sides and I am having trouble dialing in my PID...which put me...

Thank you! The temperature probes themselves (from Spike) are giving the ohm resistance changes before I even connect the QD but I'm sure the QD plug isn't helping. I'm going to give these a shot!

These are the sensors I have right now. https://spikebrewing.com/products/tc-temperature-probe According to Spike, they are class B. I have 4 of them and all 4 oscillate in resistance from .1 to .2 ohms which changes the temperature reading by 1-2 degrees. From the research I've done so far...

I have 4 RTD PT100 sensors in my system and they're all giving me temperature measurements that jump around 1-2F which makes it difficult to dial in my PID's. I checked the ohm's of each sensor and everyone seems to be jumping around which makes me think they're not accurate enough for what I...

Still available. I'd like to see this go to someone that will actually use it. I am lowering the price to $100 which INCLUDES shipping CONUS.

I have a brand new Steam Slayer system that I purchased and never actually used. After purchasing it, I purchased the spike solo system which came with a condesate lid. The information below came directly from brewing hardware where I purchased it. Includes 10' of Supply Tubing, 9gph Sprayer...

apologies for not updating this thread. It has sold. I still have the grandfather counterflow chiller for sale

I have a lightly used Grainfather Heat exchanger setup that I'm not going to be using anymore. Asking $100 plus actual shipping. COUNTERFLOW WORT CHILLER Heat Exchanger from Grainfather w/Hoses - Easy to Store https://www.amazon.com/gp/product/B07Q4MF77T/ref=pe_2313390_738100500_em_1p_0_lm...

I'm thinking that's because you joined today. :) I sent you a PM...let me know if you didn't get it.

I'm going to open it up to anyone that want to buy it. I'm asking $140 to cover $40 in shipping and I will refund any portion of the shipping that was less than $40...though I have a feeling it will be more.
