Description

LS545 Liquid Level Sensor

The LS545 is a 5-hole Capacitive Liquid Level Sensor and it provides continuous, high-accuracy measurement of a tank’s contents.

Mounting and Mechanical Features

Because it features an SAE 5-bolt mounting pattern, the sensor head footprint is extremely small.

Reventec manufactures every LS545 liquid level sensor to the length required by the customer, which eliminates the need for users to modify the sensor mechanically. As a result, this simplifies installation.

LS545 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. The probe features a carbon-fibre outer layer, because this adds strength and it ensures reliability in high vibration and extreme operating conditions.

Accuracy, Outputs and Electrical Connectivity

The LS545 is available in two accuracy specifications:

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

It is available with a range of industry-standard outputs and includes 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. Analogue 0-5V and Switch to Ground
  3. CAN and Analogue 0-5V
  4. 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.
