If it runs on a 12V DC power supply, can it just display the temperature from the sensor itself, not by cables, etc.. ?

The guage has two wires to the sensor and a hot and ground wire. The 12V goes to the sensor and back to the guage.

No it needs a connection to the sensor to work. The guage has wires for a 12v power supply, and also wires for the supplied sensor. So you need to install the sensor in your engine's water system and then hook that sensor up to the guage. Those wires are all included.

It is an engine temp gauge so it has to have the cables to connect it to the engine. The discription is a little misleading.

I used it for my car as a coolant temp sensor, but yes it is just a Thermometer, it will tell you the temperature of everything, whether it is ambiant air temps or liquid temps the sensor doesn't care. As far as I can tell it is quite accurate too.

Check if the source of 12v positive and negative of the monitor and the camera when you put reverse are reading the adequate current simustaniosly.

No. The unit works on 120 Volts Ac. If you want to run it off 12 Volt DC , you would need to purchase a DC to AC Inverter that converts 12 Volt DC ( from a battery) to 120 Volts AC. There are much cheaper ways to do this.. Just look for color LEDs that operate on 12 Volt DC... Hope this information Helps.

It displays the actual temperature, you don't see the temperature preset unless you go to the program setting mode. Just remember, it only displays celcius. I have another thermometer in my cooler that displays the temperature in farenheit. It was a fun project to wire and set up. I am a complete novice with electrical circuits, but a fairly handy person.

There is a "trigger out" port in the rear. From my understanding, this will feed a low current (up to 0.1A) whenever the unit is turned on, and this can be cabled directly to a power screen that supports the 12V trigger.

I fried a couple experimenting with voltages above 12V. The circuitry got very hot and failed. The lower voltages can be accommodated with the calibration pod. I have successfully powered it with a small solar panel with power ranges all over the board on cloudy days.

You will most likely need an upgrade on the probe wire which will is specially designed for that kind of temperature. The device itself will do just fine.

I'm sorry ... NO... I hardwired a ac to dc power supply to make my mine work in my home application, and YES it does work then and might say I've been using mine for a year now and works great. the dc power supply costs very cheap just splice it and wire it up. but to your first question the unit is an dc application and is a dc unit but can be for ac application with a power application.

I suspect if you could adjust how much voltage is going to it, you could make it adjustable, but I have no idea how you would go about adjusting the voltage. I use a computer controller that turns it on and off as needed to maintain a set temperature.

I bought this one and it does require a 12vdc input voltage. It then thermostatically controls a 12vdc device you have plugged into it.

It will turn off and on anything that is 12v powered based on the included temperature sensor.

Eric:Like you, I was unable to get a direct read from either of my 2 remote sensors. It, supposedly, will use the readings to "average" the temps, but like you, I would love to see a direct read-out on the face of the stat!Sorry I couldn't help you . . .Mike

I received an Amazon message requesting an answer to your question; problem is, I have no idea. It works OK with 12 V DC.

This unit is DC powered, so I'm assuming you are referring to a DC powered system where you are wiring directly to a 12V DC power source... try it!

Not that I have noticed but it only uses 12v and is only running for 10 seconds at a time. Running it through a converter should not be an issue

The temperature sensor plugs directly into the top of the charge controller, so there is no cable. It just measures the temp in the immediate vicinity of the charge controller. Hope that answers the question well enough!

It can't read thermocouple inputs, only voltage for analog. You can use a thermocouple transmitter to convert to a 4-20 mA signal it can read, though you are probably better off purchasing a DAQ that accepts thermocouple inputs. Measurement computing sells those too.
