Scigiene's Industrial Wireless Gen 2 0-20mA current meters are capable of measuring the current off another device or sensor, up to 20mA (DC), by connecting the leads of the sensor to the positive and ground terminals of the device being measured. Examples of interfacing devices include, but are not limited to: Current transducers (CTs) with outputs up to 20 mA, pH sensor, dissolved oxygen sensor, pressure sensor, magnetic flow meters, velocity or acceleration sensors, industrial vibration sensors, industrial accelerometers, any kind of sensor that specifies the output is in (mA) within the range of 0 – 20.
Features:
* Actual range may vary depending on environment
** Battery life is determined by sensor reporting frequency and other variables

* Hardware cannot withstand negative voltage. Please take care when connecting a power device.
** Light present 25% of day yields 125% of operating power to support 10-minute heartbeats.
*** If application exceeds 20 mA the sensor will return a maximum reading of 20 mA. If current applied to measurement port exceeds 30 mA, circuit protection and conditioning is required.
**** Solar feature’s energy harvesting circuitry works indoors with low light
