LS500 Liquid Level Sensor

LS500 Liquid Level Sensor

Capacitive liquid level sensor with an SAE 5-bolt mounting pattern, custom-built up to 450mm long.

LS500 is a solid-state capacitive liquid level sensor, capable of continuous level measurement in all common liquid types. The sensor is manufactured to your length requirement up to 450mm long, with a range of output formats, operating temperature ranges and accuracy specifications to suit most applications.


LS500 Liquid Level Sensor

The LS500 is a 5-bolt Liquid Level Sensor. It utilises Reventec’s proven capacitive level measurement technology, providing continuous measurement of the contents of a tank to very high accuracy.

Mounting & Mechanical Features

Because it features a 5-bolt mounting arrangement, the sensor head footprint is extremely small.

Reventec manufactures every LS800 liquid level sensor to the length required by the customer. This eliminates the need for users to modify the sensor mechanically and it simplifies installation.

LS800 liquid level sensors can be mounted in any orientation, including vertical inverted mounting and the sensor seals to the tank via a supplied radial O-ring seal.

We can supply sizes from 450mm to 700mm. (see the LS545 and LS570 for longer requirements). The probe features a carbon-fibre outer layer, because this adds strength. It ensures reliability in high vibration and extreme operating conditions.


Accuracy, Outputs & Electrical Connectivity

The LS500 is available in two accuracy specifications:

  • +/-1% accuracy
  • +/-0.5% accuracy.

It is also available with a range of industry-standard outputs, including an optional ‘low level’ alarm that activates when liquid drops below a calibrated level.

Output options include:

  1. Analogue 0-5V (typically calibrated 0.25V empty, 4.75V full)
  2. CAN and Analogue 0-5V
  3. CAN Only

Liquid level sensors come with a 500mm flying lead and the number of cores is dependent on the output mode(s). However, customers may specify a longer flying lead or for a connector to be supplied and fitted at additional cost. So if you require an integrated connector, please ask us about our custom sensors.

All sensors have an operating temperature range of -40°C to +125°C. In addition, an extended temperature range option is available for use in operating temperatures of up to 150°C.

Liquid Compatibility and Sensor Calibration

LS500 5-bolt Liquid Level Sensor

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

All sensors are factory-calibrated in the customer-specified liquid type, so the sensor is ready for immediate use. However, sensors can be user-calibrated in the field, for instance, if the liquid type is changed. Reventec provides free calibration software, which is available on request and in addition, lets customers compensate for non-linear tank shapes or where a non-linear output curve is desirable.
