LS1045 Liquid Level Sensor

LS1045 Liquid Level Sensor

Capacitive liquid level sensor with an AN-10 threaded mount, custom-built up to 700mm long.

LS1045 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 700mm long, with a range of output formats, operating temperature ranges and accuracy specifications to suit most applications.


LS1045 Liquid Level Sensor

The Reventec LS1045 is an AN-10-threaded Capacitive Liquid Level Sensor. It provides continuous, high-accuracy measurement of a tank’s contents.

Mounting and Mechanical Features

Because it features an AN-10 threaded mounting arrangement, the sensor head footprint is extremely small.

Reventec manufactures every LS1045 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.

We can supply sizes from 450mm to 700mm (see the LS1000 for shorter length requirements). The probe features a carbon-fibre outer layer, because this adds strength and ensures reliability in high vibration and extreme operating conditions.

LS1045 liquid level sensors can be mounted in any orientation, including vertical inverted mounting.

Accuracy, Outputs and Electrical Connectivity

The LS1045 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 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

LS1045 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, so the sensor is ready for immediate use. However, sensors can be user-calibrated in the field, as needed, e.g. if the liquid type to be measured is changed. Reventec provides free calibration software, which is available on request and in addition, it lets customers compensate for non-linear tank shapes or where a non-linear output curve is desirable.
