The OLS700D3LSH is an optical liquid level sensor designed for single-point detection. It operates on a supply voltage of 5 to 15 Vdc and is rated for a temperature range of -25°C to +80°C. This model features a 1/4” NPT external mount and provides a voltage output that is low when the sensor is in air. The sensor's infra-red detection method provides high reliability and is resistant to false triggering from foaming, making it suitable for a wide range of general liquid sensing applications.
