Product Description

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.

The standard version of this sensor is powered by two replaceable 1.5 V AA sized batteries (included with purchase). This sensor is also available with a line power option. The line powered version of this sensor has a barrel power connector allowing it to be powered by a standard 3.0 - 3.6 V power supply (Included with Line Power option upgrade). The line powered version also uses two standard 1.5 V AA batteries as backup for uninterrupted operation in the event of line power outage.

Power options must be selected at time of purchase, as the internal hardware of the sensor must be changed to support the selected power requirements.



  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.
