Methods for protecting liquid level sensors from lightning strikes

Liquid level sensor is a commonly used measuring instrument, which is widely used in many industries such as industry, chemical industry, machine tool, electronics and electric power. Summer is coming, which is a time of frequent thunderstorms. Liquid level sensor should also be protected from lightning strikes during use. So what is the method of protecting liquid level sensor from lightning strikes? Let me introduce it to you in detail.

Most liquid level sensors are designed with lightning strikes in mind, so many manufacturers have "lightning protection" for their liquid level sensors. However, the "lightning protection" here does not mean that the sensor will be safe after a lightning strike, but that this type of sensor has a lightning protection circuit. When a lightning strike occurs, even with this circuit, it cannot 100% protect the sensor, but can only reduce the possibility. During use, customers should choose to install it in a place where there is already a lightning protection device nearby; for areas with obvious lightning strikes, it is best to take special lightning protection measures; the protection circuit will prevent the sensor circuit and sensor protection from complete breakdown, and it can still be used after repair at a relatively low cost.

In short, as a manufacturer, when producing liquid level sensors, the circuit needs to adopt signal isolation amplification and cutoff frequency interference design. Customers should also have their own protection awareness when using them. Only in this way can the liquid level sensor have a longer life and better serve us.
