An inductive loop is basically the antenna of an active circuit. The inductive sensors checks the change of inductance and switches the circuit when it detects a large ferrous object. The 3" M-GAGE sensor typically performs like a 6' diameter inductive loop. In addition it is quicker and less expensive to install, less prone to damage in the unstable substrates, detects stopped vehicles. The M-GAGE is easily wired into existing control infrastructure and can also be used as a lowprofile photo radar trigger.
Youâ€™ll only program the sensor after itâ€™s been buried. This is because you need to teach the sensor the ambient magnetic field. Typically the sensor will be connected to your machineâ€™s interface module which you will use to program the sensor.When the sensor has been taught, the indicator light will blink 12 times. Banner does offer a sensor interface module SIM-525T.
The M-GAGE can detect ferrous objects from a semi-truck to a motorcycle. Although the range is somewhat limited, the
M-GAGE will sense street legal motor scooters such as an 80cc Yamaha Zuma,
Through testing, we have determined that youâ€™ll get the best results by burying the sensor in the earth. Weâ€™ve had
reasonable success when the sensor is up to 24 inches above the earth. While we donâ€™t recommend mounting the sensor
higher than 24 inches, there are occasions when it can be done. You will need to use our free monitor software to evaluate
magnetic anomalies which may occur from elevation.
The M-GAGE uses what are essentially miniature compasses (magnetometers) to detect magnetic field changes along
any of three axes. The M-GAGE is programmed to react to magnetic field changes. When a large ferrous object like a truck,
car or motorcycle, for example, alters the ambient magnetic field, the sensor will detect the change. The sensorâ€™s discrete
outputs will switch when the preset threshold is achieved.
