High pressure and high temperature four wire drum level gauge is used for heating

  The drum level gauge adopts the tomography technology
The dielectric constant and temperature of liquid phase and gas phase in the level gauge are dynamically scanned and analyzed through a special sensor for dynamic compensation
After the comparative calculation of the system software, the 4 ~ 20mA standard current signal proportional to the boiler liquid level and four groups of SPST solid-state relay switching signals are output
The drum liquid level gauge adopts the structure and is resistant to high temperature and high pressure
Among them, the transmitter uses the relationship between the change of liquid level and the change of electric capacity generated by the measurement probe, Through the special mode system software, the detected capacitance change is output with 4-20madc standard signal proportional to the material level after various compensation calculations

1
Strong practicability and simple operation
The zero point and range of analog circuit are involved with each other and need to be calibrated many times; The intelligent circuit adopts key setting and one key calibration, and the operation is simple and accurate

2
The display is stable
Analog circuit is difficult to achieve large damping and sampling time, so that in the production process, slightly large gas volume or liquid level micro movement will lead to the instability of monitoring instrument display and the visual fatigue of monitoring personnel; The intelligent liquid level gauge adopts digital software filtering technology, which is not affected by gas volume and liquid level swing
It can not only quickly * transient change, but also display the average effect of liquid level, which is stable and accurate
