Wireless explosion-proof fuel level sensor DUT-RV5


The DUT-RV5 sensor meets the requirements Of the technical regulation of the Customs Union 012/2011 "on the safety of equipment for operation in explosive environments" and can be used in an explosive zone of class "0". explosion protection Marking: 0ex ia IIB T3 Ga X.

The "X" mark in the explosion protection marking indicates that special conditions must be observed when operating the level sensor.

  • non-Metallic parts of the level sensor housing should be wiped with a damp cloth once a month.
  • only the type e element specified in table 11 of GOST 31610.0-2014 (IEC 60079-0:2011) may be used as a power source for the level sensor.
  • it is Prohibited to replace the battery in explosive environments.
  • Protect the metal parts of the level sensor from collisions and friction to avoid the risk of ignition from friction sparks.

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, on average 10 years. Thanks to this, there is no need for an additional spark protection unit, the requirement for galvanic isolation of the power supply circuit and the data transmission circuit is met, and any problems in the operation of the sensor associated with power supply are eliminated. The sensor is always in working order. Removing the battery from the car will not affect the operation of the sensor.

- The sensor transmits data to the receiver via a 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 the sensor and eliminates sabotage by drivers during its 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 sensor's ability to operate without a terminal significantly reduces the initial cost of installing fuel monitoring systems.

Data is read from the sensor's memory remotely, using a USB radio Reader connected to a personal computer. The data received from the sensor is analyzed 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 sensor 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 receiver can process and transmit data to the terminal from 80 sensors.

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

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.
