Monnit WIT™ Wireless 0-20 mA Current Sensor   Buy Wireless 0-20 mA Current Sensors!

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.
Monnit WIT Wireless Sensor Specifications
  • 900, 868 and 433MHz operating frequencies
  • 250 - 300 ft. non-line-of-sight device range*
  • Replaceable 3.0V battery
  • At 1 hour heartbeat setting, coin
    cell battery will last ~ 1-2 Years. **
     
  • Interfaces with sensors between 0-20 mA.
  • Small size is ideal for embedded applications.

* Actual range may vary depending on environment.
** Battery life is determined by sensor reporting
    frequency and other variables.

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.
