The submersible level transmitter is a high-temperature gas-guided level transmitter, which integrates the sensor and signal processing circuit in the junction box. This design allows the sensor to come into contact with the gas immersed in the cartridge, which then transports the gas to the sensing element through the impulse tube. This innovative product solves the challenges associated with measuring high temperature liquid levels by avoiding direct contact between the sensor and the medium being measured. Immersion level gauges are specially designed to meet the needs of measuring liquid levels in high temperature or highly corrosive liquids. Its unique features make it ideal for applications requiring small to medium range measurements and environments with highly corrosive media. One of the main advantages of immersion level gauges is the ability to measure liquid levels in high temperature environments. Traditional liquid level measurement techniques often struggle to accurately determine the level of liquids at extreme temperatures due to sensor limitations. However, with immersion level gauges, the sensor is not directly exposed to the medium being measured. Instead, it interacts with the gas present in the immersion cylinder, which acts as a protective barrier. This method ensures accurate and reliable level measurement even under harsh high temperature conditions.
