Description

Monnit’s ALTA 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. WARNING: Use caution when interfacing to the Monnit 0-20mA Current meter. Negative voltages, AC Voltages , DC Voltage exceeding 3.6V CAN DAMAGE the electronics of the wireless sensor. Monnit is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.
