CR-6031 High Pressure Type

Short Description:

CR-6031 intelligent boiler level sensor is based on capacitance measurement principle. It uses positron-emission tomography technology to measure and analyze the dielectric constant of liquid and vapor medium,temperature,pressure and other parameters in the cylinder, After the microprocessor processing, the output conforms to the industrial standard 4-20mA current signal,RS485 digital signal can also be output.

Liquid level sensor compensates automatically in real time during operation without the affect of temperature, pressure, medium changes, good long-term stability. It is a full working condition, high cost performance drum level sensor which is suitable for boiler drum of generator set water level measurement like power plant, steel plant, cement plant.

Technical advantages:


1. Two-wire system 4-20mA current loop,resolution reach to 0.1mm,error less than 1%.

2.  Positron-emission Tomography can be used to continuously measure and compensate the dielectric constant of liquid and vapor media.  

3.With the patented automatic calibration function, the liquid level sensor automatically calibrates zero and full points in the process of emptying and adding water.

4. The liquid level sensor is directly connected to the boiler drum body, the capacitance sensor directly contacts the level, so the measurement is real and reliable.

5.  The structure of the steam condensing chamber which has obtained the invention patent can ensure the consistency of the liquid level sensor and the temperature of the boiler drum body to the greatest extent, so as to ensure the real measurement of water level;It can effectively achieve vapor water separation, prevent the capacitance sensor surface hanging water; It can also avoid the impact of steam and water on capacitance sensor.

6. Inversion structure, automatic seal, to ensure the safety and reliability of electrical parts.

7.The overall technology is advanced, safe, reliable,durable.
