    Temperature Probe Testing

    Harald, Thanks for insights am sure this is "bang-bang" type of device because everything functions till it tries to turn on heater and then power pack goes into protection mode. This is smallest wattage sous vide I could find, already had the power pack (live in hurricane region so actually...

    Temperature Probe Testing

    Okay I'm BACK! Bought sous vide device, 120v/750watt, plugged in to 120v outlet will heat 1 gallon of water at 120°F to 140°F in about 5 minutes. After that it maintains temperature within 4/10ths of a degree, which is perfect for my testing parameters. Here's the problem: The portable power...

    Temperature Probe Testing

    Crutschow: Think this will work? Own a portable power supply (Black & Decker) with the following ratings: Buy smallest wattage sous vide (700W) build insulated gallon paint can, fill with 110° water, then let it get to desired temperature and take probe readings. Can dose water bath to get...

    Temperature Probe Testing

    crutschow: Currently use a 20oz insulated plastic container that's filled with hot (110°±) water and adjusted with boiling water to desired test temperatures. So could do same with this setup and all it would have to do is maintain the temperature of test water.for about 30 minutes. Heat loss...

    Temperature Probe Testing

    Thanks for the quick answers to my questions! nanren888: Currently using a digital scientific thermometer for reading water temperature and probes need to test within 4° of thermometer reading to pass inspection. Not sure what traceability aspect you are asking about, but form for testing is...

    Temperature Probe Testing

    Twice a year I test temperature probes on kilns for heat treating wood pallets. Would like to build a small, portable, constant temperature, water bath unit that can maintain a temperature of 140°F AND 170°F. The probes have set points of 130° or 160° and these are minimum test temperatures...

    Cracked Dell monitor conversion to light source

    Pictures show in thread but not in preview so not sure what happens when I post Dell 24" Monitor MV230HM-N30 B4 S2318HN/S2318NX Cat knocked over and broke LCD screen, am trying to convert to LED light utilizing existing LED edge back light strip (4 groups of 16 LED lights=64 total) These are...

    Aquarium lights and fan

    Thanks BJ, switches in top diagram would be double pole, single throw? What type of relays would I need for 2nd diagram?

    Aquarium lights and fan

    It's all 110ac, switches actually control the ballast for lights and the fan circuit goes to transformer that lowers voltage to 12v for small fans. Two incoming 110v power circuits are available, or could use a single power circuit. Lights are 18watts each and fan is small 12Volt-2/10s (.2) amps

    Aquarium lights and fan

    Two lights that are each on a separate switch, black & white wires for each light. One fan, black and white wires. Fan is wired to come on when switch for light #1 is turned on. Light #2 switch only turns on light. Is it possible to rewire fan to come on with either light and with both lights...

    HV diode

    elebish, Ordered a T3512 from site dorke had listed above, might try the $12 one you suggested next! The arcing was inside the magnetron just below where wires are attached, this is NEW development after changing diode. Could wrong or bad diode cause this to happen? No arcing in the oven and...

    HV diode

    Know it's been a while, installed new diode and results were same! Ran test on NEW diode and it seems to be BAD! Guess $.99 is NOT the way to go. Upon powering microwave up (after replacing diode) arcing was observed in the magnitron. Shut it down immediately and magnitron still checks out...

    HV diode

    Found this one at HV STUFF think it would be okay? Doesn't appear to have cathode markings, but guess I could test for flow direction? 300mA 10kV 100nS High Voltage Diode HV Rectifier High Frequency Repetitive Peak Reverse Voltage 10kV Average Forward Current 300mA Maximum Surge Current 30A...

    HV diode

    What am I missing here? Alibaba wants you to buy minimum units that end up costing $100 or so, how do you buy 1? Thanks for info, now if I can find one. No help from local Sharp service center or electronics stores. Where now?

    HV diode

    Microwave Sharp R520LK, diode T3509-6D, after looking around for replacement, think this is a 300mA, 9KV diode, and is no longer available from Sharp. Not electronic savy enough to know what can be used as replacement. Local appliance part store has "universal diode", but they could not tell...
