0-20 mA Current Sensor

Capable of measuring the current off another device or sensor, up to 20mA (DC), by connecting the leads on the Monnit WIT 0-20mA Current 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 WIT 0-20mA Current sensor. Negative voltages, any kind of AC Voltages, or DC Voltage exceeding 3.6V WILL DAMAGE the electronics of the Monnit WIT. Monnit is not responsible for troubleshooting, replacing or reimbursing damages incurred by disregarding this warning.

Need Longer Battery Life?
Monnit WIT2 Sensors provide the same features and benefits of our standard sensors but with the added value of AA batteries. The AA battery option is more robust at a wider temperature range and provides extremely long life for quicker heartbeats.

2 replaceable AA 1.5V batteries.
At 1 hour heartbeat setting, included AA batteries will last more than 4 Years. **
Robust sensor housing.

** Battery life is determined by sensor reporting
frequency and other variables.
