Should be enough to build a rack to build a basket to process a dozen rolls of 120, or 8x10 sheets on hangars. Metrix: Enough volume I am thinking to temper a half dozen 1L bottles. this will circulate the bath giving more uniform temperatures.Īmazon seems to have plenty of inexpensive PID temperature controllers If it's large bath you might consider adding an immersion pump. A problem with an high power heating element is that even in water it gets much hotter local to the element then the set temperature thus it's difficult to get a stable uniform bath temperature even with a PID controller. If it is small then something like this slow cooker might be a good starting point as the heater element is already built in. Wayne what volume of water bath do you want to control the temperature of? PID isnt a device its a control meathod used by the device, essentially three time values for controlling a process.

I don't need something like this to develop films, a bucket and hot water tap works just fine, but to develop prints, this could be useful. Wayne Stevenson edited this topic 106 months ago.

#JOBO CPE 2 LIFT INSTALLATION CODE#
Code apparantly says you need a component that will not run continuosly over an 80% load.Ī 14 guage wire is going to be code for my setup. Which will run around 9amps, so I went with a 15amp solid state relay (SSR). It's meant for 220v but halving the voltage will give it 1/4 wattage, 1000w. Iam going larger and deeper so I ordered a 4kw (4000w) heating element. Learning about electricity again for the first time since high school, I have been doing some research on this. Aside from the wires, heating element, a GFCI (I would highly recommend if you'll be sticking your hands in), and something to stick it in (people seem to be using tupperware tubs for their cooking needs), one system's worth will run you just under $50.

Put a water pump in there and you have yourself a system that will monitor and intelligently learn how to keep the liquid at the proper temperature all the time. Then put in a temperature sensor probe (thermocouple). You then wire a heating element to the relay. You bring power to the PID, and wire on a solid state relay (SSL) to it (some have relays built in but the highest watt I have seen it power at 110v is 750w) which I suppose should be fine for a small tempering bath. While I do not fully understand it all, I just finished ordering parts to build my own.going to build myself some dip and dunk tanks that I can load a ton of reels in, that can double as tempering bath if wanted. You have a component called a PID, and you hook a temperature sensor to it, and program in a target temperature, and it will run a program to figure out how to intelligently control a heating element to maintain the temperature without going over or under the temperature that you tell it.Īnd someone found a ready made unit to temper his chemistry and provided a good explanation of what they are. Or for building coffee / esperesso machines. They are a device that people are making DIY for cooking food in bags(?) at a specific temperature. So I just learned about Sous Vid Cookers.
