LS800 Liquid Level Sensor

The LS800 liquid level sensor utilises Reventec’s proven capacitive level measurement technology, providing continuous measurement of the contents of a tank to very high accuracy.

Mounting & Mechanical Features

Featuring an AN-8 threaded mount, the footprint of the sensor head is extremely small with all control electronics mounted within the sensor head. Sealing of the sensor to the tank is made by way of a radial O-ring seal (supplied).

All LS800 liquid level sensors are manufactured to the specific length required, up to 450mm long (see the LS845 for longer requirements). This eliminates the need to cut down or mechanically modify the sensor, while ensuring it is a perfect fit for the application.

LS800 liquid level sensors can be mounted in any orientation, including vertical inverted mounting.

Accuracy, Outputs & Electrical Connectivity

The LS800 is an advanced device with two accuracy specifications available: +/-1% accuracy or +/-0.5% accuracy.

The device is available with a range of industry-standard outputs, including an optional low level alarm that switches when the liquid drops below a calibrated level.

Output options include:

  • Analogue 0-5V (typically calibrated 0.25V empty, 4.75V full)
  • Analogue 0-5V and Switch to Ground
  • Analogue 0-5V and CAN
  • CAN Only

All sensors are provided as standard with a 500mm flying lead (number of cores dependent on output mode(s) selected. Customers may specify a longer flying lead, or for a connector to be supplied and fitted, at additional cost. If you require an integrated connector please request a custom sensor.

All sensors have an operating temperature range of -40°C to +125°C. For high-temperature (typically oil) level measurement applications, an extended temperature range option is available, allowing the sensor to be used in operating temperatures of up to 150°C.

Liquid Compatibility and Sensor Calibration

LS800 is compatible with all common liquid types, including fuel, oil and diesel. Sensors are available for compatibility with polar liquids including water and coolant, and bio-fuels such as Ethanol, Methanol and blends.

All sensors are factory-calibrated in the customer-specified liquid type, ensuring the sensor is ready for use out of the box. The sensor can be re-calibrated as and when necessary (for example, if the liquid type to be measured is changed), using Reventec’s free calibration software (available on request).

The calibration software also allows the sensor to be calibrated to compensate for non-linear tank shapes, or where a non-linear output curve is desirable.
