Detector magnetic DM-217Cx , Sensor for measurement of vehicle presence
(to be installed under or on the surface layer of the pavement. The detection
principle is based on continuous measurement of geomagnetic field.
The same hardware as DM-217Cx , with firmware upgrade could be used as well
for traffic census – model type DM-218Cx.
Installation: by pavement drilling, 100 mm in diameter
Batery lifetime: 10 years (20 cars/ per day turnover ) – measurement of vehicle
presence, 3 years – traffic census (5 minutes measurement interval)
Modular hardware detector structure enables replacement of the batteries to
Power supply: battery, lithium-thionyl chlorid (Li-SOCl2)
RF communication: LoRa, Sigfox
Operation temperature: −40 °C / +85 °C
Dimensions: diameter 97 mm, height 130 mm
Coating: material ABS, IP68, black
