Level Measuring Systems

for Intervention and Fire Fighting Vehicles

Blaulicht

IP67 ENThe VOTRONIC tank displays had been designed for precise level measuring in intervention vehicles. The display system consists of a tank sensor for the measurement at the tank and a separate display unit. If the standard voltage signal 0-10 V is used, operation of several displays at the tank sensor is also possible.

The design of all the components is very robust, they are sealed water-tightly, they are suitable for 12 V and 24 V board voltage and they are completely vibration-proof. The units are processor-controlled and internal safety checks are continuously executed.

Being adapted to the industrial standard signals (0-10 V or 4-20 mA), these components allow an operation with other brands. But an operation with the VOTRONIC tank display system for camper, caravan, boat, is not possible.

The LED Tank Display HE is a special development for heavy- duty use in fire-fighting vehicles, and it serves for exact indication of the tank level in the vehicle. As panel version, it can be installed in display panels. It is available with two standardized measuring signals: 0-10 V or 4-20 mA. Thus, the unit is suitable for the VOTRONIC Tank-Sensor FW, as well as for transmitters of other manufacturers with identical standard signals.

The tank level is represented by means of 10 super-bright light-emitting diodes in form of a continuous tricolour luminous bar allowing convenient reading of the tank level. A photocell controls the brightness of the display in such a way, that dazzling at night is avoided and that the readability is excellent, even in case of direct sunlight during the day or view from an unfavourable angle. A particular advantage is the compact design and the small mounting depth. Simple parallel connection of up to 4 LED Tank Displays HE 010 allow a control of the tank level at almost any location of the vehicle. The display unit is sealed water-tightly, it is vibration-proof and it is protected against reverse battery and overvoltage.

The LED Tank Display HE 420 can also be operated with sensors 4-20 mA, and it is connected to the negative pole at the input side.

The VOTRONIC Tank Sensor FW had been developed for level measuring of water and hydrous media in metal and plastic tanks of fire fighting vehicles. The sensor is installed outside at the tank top or near the tank. Only the flexible measuring probe has to be hung up in the tank itself.

Dependent on the level, the sensor supplies continuous standard signals (voltage signal 0 - 10 Volts or current signal 4-20 mA) for connection of various display and evaluation units, such as the VOTRONIC LED Tank Display HE, pointer indicators or external units, such as board computers etc. The sensor can be used for a total of up to 4 LED Tank Displays HE 010.

  • No mechanically moved parts, robust fully electronic capacitive measuring method
  • Easy adaptation to the existing tank height
  • Simple calibration, which can be adjusted freely and separately for empty and full level
  • Independent of pressure, no falsification of measured values in case of overpressure, pressure filling etc.
  • Linear, continuous signal of the level
  • Protection against reverse battery, overvoltage, short-circuit and overload
  • Sealed absolutely waterproof and vibration-proof
  • Safety due to internal test procedures being executed continuously (processor control)
  • Output signal voltage 0-10 V: Load min. 1 kOhm, three-wire system, or
    commutable to output signal current 4-20 mA: Load max. (UB-7 V), 20 mA, two-wire system
