LS100 Liquid Level Sensor

The LS100 is a liquid level 1-bolt sensor. It utilises Reventec’s proven capacitive level measurement technology, providing continuous measurement of the contents of a tank to very high accuracy.

Mounting and Mechanical Features

Featuring a single ⌀4.2mm mounting bolt hole, the sensor head footprint is extremely small with all control electronics mounted within the sensor head. Sealing of the sensor to the tank is made via a radial O-ring seal, which is supplied.

LS100 liquid level sensors are manufactured to the length required up to 450mm long (see the LS145 for longer requirements). As a result, this eliminates the need for users to cut down or mechanically modify the sensor for instance and it ensures a perfect fit for the application.

LS100 liquid level sensors can be mounted in any orientation, including vertical inverted mounting.

Accuracy, Outputs and Electrical Connectivity

The LS100 is an advanced liquid level 1-bolt sensor with two accuracy specifications available:

  • +/-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:

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

Liquid level sensors come with a 500mm flying lead with the number of cores dependent on the output mode(s). Alternatively, customers can 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 a standard operating temperature range of -40°C to +125°C. In addition, an extended temperature range option is available for high-temperature (typically oil) applications. This enables the sensor to be used in operating temperatures of up to 150°C.

Liquid Compatibility and Sensor Calibration

LS100 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.

Our 2-bolt liquid level sensors are ready for immediate use because they are factory-calibrated in the customer-specified liquid type. However, they can be user-calibrated in the field, as needed; for instance, if the liquid type to be measured is changed. Reventec provides free calibration software, which is available on request and it enables compensate for non-linear tank shapes or where a non-linear output curve is desirable.

Benefits at a glance

  • Manufactured to length, so it’s a perfect fit straight from the box with no mechanical adjustment required
  • Wide range of output modes so it’s compatible with most industrial and automotive instrumentation and control electronics
  • Compatible with a wide variety of liquids
  • Solid-state with no moving parts, so it’s ideal for use in extreme operating environments
  • High temperature variant available for monitoring high-temperature oil up to 150°C
  • Mount at any angle, including inverted, so it’s highly flexible
