Measuring the control temperature of the liquid level , these two complementary functions can be accomplished by appropriately combining an integrated circuit. This circuit monitors the temperature of the liquid in the liquid bath and disconnects the warming element if the liquid level in the tank drops to a predetermined point. This circuit keeps the liquid level within a few millimeters and maintains the liquid temperature constant.

Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
