Monnit wireless 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.
Monnit Industrial Sensors come in an IP65, NEMA 4X, CE rated, sealed, and weatherproof enclosure. They are powered by a single, replaceable, Industrial grade 3.6 V battery (included).
An optional solar powered version is also available. The solar powered version includes a Lithium Iron Phosphate rechargeable battery in conjunction with a solar power cell to keep the battery charged and at optimal capacity. If there is no light present at the solar cell, the battery alone could continue to power the sensor for up to 5 years.
* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting frequency and other variables.
