DT7.4

Fuel Level Sensor DT7.4

Features

no moving mechanical parts
extended supply voltage and operating temperature ranges
integrated temperature compensation
galvanic isolation of sensor housingfrom the common power cable
inverse-polarity, short-circuit and misconnection protection
modifications with digital or analog interface
modifications with different harness length (from 630 mm to 9 m)
additional protection of the connection cable with metal hose or corrugated hose

Used to monitor diesel fuel level in fuel tanks of motor vehicles and road construc - tion machinery.Used as part of satellite vehicle monitoring systems to control fuel consumption.

The sensors are designed to allow reducing length of the measuring tube to fuel tank height (down to 200 mm).
