Wireless fuel level monitoring sensor DUT-R7

DESCRIPTION

The DUT-R7 wireless fuel level sensor is designed for high-precision measurement of the level of fuel or other current-carrying liquid in fuel tanks and reservoirs.

The sensor measures the liquid level using the capacitive method. The maximum depth of the fuel tank is 5 meters.

Advantages

We took into account Your wishes and made the installation and maintenance of the sensor easier and more convenient in comparison with the previous model, upgraded the radio frequency part of the DUT-R7 transceiver. And that's not all…

The sensor does not have an external power supply. There are no wires between the sensor and the terminal.

The sensor does not have an external power supply. There are no wires between the sensor and the terminal

- The sensor is powered by a built-in battery, which is designed for continuous operation of the sensor for 8 years. This eliminates the need for galvanic isolation of the power supply and data transmission circuits, eliminating any problems in the operation of sensors related to power supply. The sensors are always in working order. Removing the battery from the car does not affect the operation of the sensors.

- The sensor transmits data to the radio signal receiver (ORS) over the radio channel. The range of reliable data transmission is sufficient to install the sensor on all types of vehicles. The absence of wires significantly facilitates the installation of sensors and eliminates sabotage by drivers during their operation.

The sensor can work without a terminal

- The sensor has a built-in real-time clock and internal memory. All measured data is stored in the sensor memory for 60 days. The ability of the sensors to operate without a terminal significantly reduces the initial cost of installing fuel monitoring systems.

Data is read from the sensor memory remotely, using a USB radio Reader connected to a personal computer. The analysis of the data received from the sensors is carried out by a special program.

The sensor can work with any terminal

- The sensor is connected to the terminal by a bundle: "Sensor-Receiver-Terminal". The receiver receives data from the sensors and transmits it to the terminal via the RS-485 bus (LLS, Modbus Protocol) or via the frequency input. Data transmission to the terminal via the analog input is possible via the interface Converter.

One radio signal receiver (PRS) can process and transmit data to the terminal from eighty sensors.

The sensor also records all measured values in its own memory, which are available for the last 60 days. Recording data in the sensor memory eliminates loss of information and sabotage by third parties.

The sensor has an easy and convenient calibration of the fuel level monitoring module

You can choose one of four ways to calibrate the fuel level module:

  1. You can use the calibration default.
  2. Calibration by specifying the length of the measuring tube.
  3. Calibration of the upper and lower border (Full/Empty).
  4. Entering the calibration table into the sensor memory.
