SST Liquid Level Sensor

Description Attachments

The SST Liquid Level Sensor is an advanced single-point liquid detection device that communicates via a TTL compatible push/pull output. It boasts a miniature design, making it ideal for installations in compact spaces. With no moving or mechanical parts, this sensor is designed to be both reliable and durable.

This sensor operates using an infra-red LED and phototransistor positioned at the base of the sensing tip. When the sensor is in air, the optical coupling between the LED and the phototransistor is strong. However, when the sensing tip is immersed in a liquid, the infra-red light escapes, causing a shift in the amount of light reaching the phototransistor and triggering a change in the output state.


  • Supply Voltage: +4.5 Vdc to +15.4Vdc
  • Output Current: 100mA
  • Temperature Range: -25 to +80⁰C
  • Polysulphone Housing Tip
  • M12 threaded connector (mounted from outside)

The SST Liquid Level Sensor is particularly beneficial for applications where accurate liquid detection is crucial. It's perfect for use in a wide range of industries, from food and beverage production to chemical processing, due to its robust design and wide temperature range. The sensor's polysulphone housing tip is resistant to many chemicals, ensuring its longevity in various environments.

With its M12 threaded connector, this sensor can be easily mounted from the outside, making it a convenient option for various applications. The sensor is also straightforward to use, thanks to its supply voltage range of +4.5 Vdc to +15.4Vdc and an output current of 100mA.
