Profile: Demico, Inc. is a designer and manufacturer of electronic instruments & controls for the power & gas utilities. Our products include battery transducer, battery tester, DC voltage transducer, temperature transducer analog output, temperature transducer pulse output, temperature sensor sunshield, wind speed transducer and wind bearing transducer. We also deal with ambient light transducer, power factor transducer, single phase socket mount recording averaging voltmeter, peak demand control and wind monitor & control. Our battery transducer is a unique transducer which is powered from the battery it is monitoring, eliminating the need for an additional power source. This transducer operates down to approximately half of the maximum specified input voltage and the output is an isolated current source which is linearly proportional to the input voltage. A simple resistor from 0 to 10,000 ohms is all that is required to scale and interface to a standard RTU analog input. The transducer output's galvanic isolation from the battery eliminates ground loops and ground referenced noise.
