Cement Drum Sensor DZ300

DZ300 is a magnetic proximity sensor which is specially designed forrotation speed and orientation detection.

Supports RS232 output and high/low digital output. RS232 outputs the rotation speed in rpm and orientation in specified protocol of Dingtek. The high/low digital line outputs high or
low according to the different orientation, clockwise or anti-clockwise.

Applicable for rotation system, the speed of which is in 0-120 rpm. Especially it can be applied to status detection of mixing or discharging for the cement drum. Therefore, it can be used to detect if there is illegal discharging (output/unload) for the cement drum vehicle. Also, it can be used to detect the status of the fixed cement drum device with the embedded system or SCADA.
