Votronic Tank Sensor FW 120

The VOTRONIC tank gauges were designed for accurate level measurement in emergency vehicles. A display system consists of a tank sensor for measurement at the tank and a separate display unit. When using the standard voltage signal 0...10 V, several indicators can also be operated on the tank sensor.

All components are very robustly constructed, waterproof, designed for 12 V and 24 V on-board voltage and completely vibration-proof. They are processor-controlled and continuously run safety checks internally.

The VOTRONIC Tank Sensor FW is designed for level measurement of water and water-containing media in the metal and plastic tanks of fire-fighting vehicles. The sensor is mounted outside on top of the tank or close to it. Only the flexible measuring probe has to be hooked into the tank itself.

The sensor supplies stepless standard signals (voltage signal 0...10 volts or current signal 4...20 mA) corresponding to the linear level for connection of various display and evaluation devices, e.g. VOTRONIC LED Tank Display HE, pointer instruments or third-party devices such as on-board computers, etc. The sensor can be used to measure the tank level. The sensor can operate up to 4 LED Tank Display HE 010 units.

• No mechanical moving parts, robust fully electronic capacitive measuring method
• Easy adjustment to the specified tank height
• Exact calibration, freely adjustable separately for "empty" and "full
• Pressure-independent, no falsification of measured values in the event of overpressure, pressurised refuelling or the like
• Linear, stepless signal of the fill level
• Protection against polarity reversal, overvoltage, short circuit, overload
• Absolutely waterproof and vibration-proof encapsulation
• Safety due to permanently running internal test procedures (processor-controlled)
• Output signal voltage 0...10 V: load min. 1 kOhm, three-wire connection, or
  switchable to output signal current 4...20 mA: Load max. (UB-7 V) 20 mA, two-wire connection

Note:These components, which are matched to industrial standard signals (0...10 V or 4...20 mA), allow operation with other makes, but do not work with the VOTRONIC fuel gauge system for motorhomes, caravans and off-road vehicles.
