Scigiene's Wireless Gen 2, 0-20 mA Current Meter is capable of measuring the current off another device or sensor, up to 20 mA (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. Scigiene's wireless sensors are ideal for pharmaceutical, medical and other high tech applications where loss of data is unacceptable. These also have an amazing range of over 1000 ft. with 10 year battery life and can be remotely upgraded via network connections. These are truly the most advanced wireless sensors available.

1. If application exceeds 20 mA the sensor will
return a maximum reading of 20 mA. If current applied to measurement port exceeds
30 mA, circuit protection and conditioning is required. 2. Temperatures colder than the rating are acceptable
if the cable is not moving or vibrating. 3. Operating and storage altitude without DC power
supply is -30.48 to 9144 m (-100 to 30000 ft). |
