| I would like to monitor the level in my water storage tank using a pressure transducer, but the tank is a couple of hundred feet away from the area where I want to mount the display unit. How far can I send a 4-20 mA signal and what wire do I use? |
|
| A good rule of thumb for transmitting 4-20 mA signal is 1000 feet using shielded pair, 20- or 22-gauge wire. Beyond that distance, some type of amplifier or re-transmitter is usually needed. |
