The advantage of the characteristics of the liquid level sensor and its measurement

Liquid level sensor is also can be widely used in liquid level measurement, because of its principle and characteristics of the change of liquid level sensor of material level parameters can be converted into a standard current signal, remote transmission to the operating room, for secondary instrument or computer for centralized display, alarm and automatic control, and its good structure and installation method can be applied to high temperature and high pressure, strong corrosion, easy to crystallization, prevent jams, prevent cold junction and under special conditions, such as solid powder, granular material level, material level or the level of continuous testing, can be widely used in all kinds of industrial process control testing. A, liquid level sensor features:

1, liquid level sensor, intelligent signal processing technology, high precision, good stability, strong anti-jamming performance.

2, using three levels of lightning protection design, good resistance to lightning effect.

3, full, and zero long-term stability can amount to 01% FS. Within the scope of the compensation temperature 0 ~ 70 ℃, the temperature drift less than 01% FS, throughout the allowed working temperature range is less than 03% FS.

4, solid structure, no moving parts, high reliability, long service life, has the reverse protection, current limiting protection circuit, when the installation is negative answer the reverse will not damage the transmitter

5, easy installation, simple structure, economy is durable.

6, liquid level sensor is suitable for network acquisition of multipoint pressure parameters and bus supports 255 devices.

2, craft: diffusion silicon ceramic capacitance sapphire optional

the 1, not blocked airway, airway cannot fill the

3, liquid level sensor, do not use sharp things to bad diaphragm

4, however, do not short circuit using the

5

6, using the full range of below 60%, the effect is best, the longest service life of the liquid level sensor can be widely used in petroleum, chemical industry, metallurgy, energy, light industry, monitoring, environmental protection, urban water supply, food processing, medicine, water engineering, air conditioning engineering, etc.
