The LG-D20H-230AC is a Polym-Elta probe-type liquid level sensor for applications such as sodium hydroxide storage tanks and nonconductive liquids. It is a low-power, non-contact, non-intrusive magnetic-fortified analog sensor that utilizes the Hall effect. Its probe is made of stainless steel and has a durable silicone O-ring which makes it suitable for submersion up to 180 or 360mm (depending on the model). In addition, the probe has a very small deadband and a wide dynamic range which make it suitable for various levels of fluid interfaces. Other features include a high-temperature rating of up to 105°C, a quick action response time, and a choice of wiring options based on the application. With its reliable and accurate ultrasonic sensing technology, the LG-D20H-230AC is an ideal liquid level sensor for companies who need reliable and accurate liquid level monitoring.
