Monitor animal feed fat tank levels with this submersible sensor. Features 4-20mA output, integrated PT100 RTD, and high-temperature resistance.
The LMK458 submersible level sensor with 4-20mA output and integrated PT100 RTD temperature sensor is designed for continuous level measurement in animal feed fat tanks. The sensor’s flush diaphragm and high-temperature resistance (up to 125°C/257°F) make it ideal for direct immersion in fats and oils, even in processes with elevated temperatures. The open diaphragm design prevents clogging and ensures accurate level measurement, while the RTD provides real-time temperature data for process monitoring and control.
This sensor is particularly well-suited for use in feed production facilities, where maintaining precise levels of fats and oils is crucial for ensuring the quality and consistency of animal feed. The 4-20mA output signal can be easily integrated with existing process control systems, enabling automated level monitoring and control.
