R180 4-20mA Sensor Tag
The R180 4-20mA Sensor Tag is designed for deployment with industrial process control equipment, devices, and sensors
that use 4-20mA current loops. This enables wireless transmission of industry-standard 4-20mA sensor readings for
specialty and industrial applications.
R180 4-20mA Sensor Tag Details
The 4-20 mA current loop is a common method of relaying sensor information in monitoring applications with a need for
analog sensors. The 4-20 mA sensor is a device used to measure physical parameters (such as temperature, pressure,
speed, liquid flow rates), with 4 mA representing the lowest end of the sensor range and 20 mA representing the highest
sensor reading. The R180 Sensor Tag allows the 4-20 mA monitoring data to flow over the RF Code radio frequency
infrastructure. Data transmitted from the sensor tags is captured by the RF Code reader infrastructure and relayed to the
RF Code software (Zone Manager/Asset Manager) or into other 3
rd
-party applications. The 4-20 mA current loop readings
can be visualized in Asset Manager via:
Live table and map views
Interactive graphing
Scheduled reports and graphs
Alerting and thresholding
