Stainless steel reed tube level gaugeIt consists of two parts: a liquid level sensor and a converter, consisting of several reed switches and resistors installed inside a ф 20 stainless steel tube, fastened on the outside of the measuring tube. The intelligent pressure transmitter converter is composed of electronic modules and installed in the junction box of the sensor. The sensor converts the change in liquid level into the magnitude of resistance through the magnetic coupling effect of magnetic steel, and then converts it into a 4-20mA.DC standard current signal through a converter, which is sent to the liquid level display instrument or other secondary instruments to achieve long-distance liquid level/analog display. The alarm is composed of a reed switch or a reed switch with memory and an explosion-proof junction box, fastened on the outside of the measuring tube. The alarm is driven by a magnetic steel at the top of the float connecting rod, and the output alarm switch signal is sent to the liquid level display control instrument or other secondary instruments to achieve remote liquid level upper and lower limit alarm and light display.
Reduce the number of calibrations for stainless steel reed tube level gauges to save time. If applicable, the techniques should be those that do not require calibration and are independent of the physical properties of the fluid. Secondly, the less contact between the instrument and the processing, the better, as this way the processing process will not affect the instrument. From this perspective, pressure measuring elements and nuclear measuring instruments are equipment that require holes in the reaction vessel, such as ultrasonic level gauges and non-contact radar level gauges, but do not need to be inserted into the interior of the reaction vessel, so they do not affect stirring or other equipment inside the vessel. Guided wave radar level gauges, stainless steel reed tube level gauges, magnetostrictive probe level gauges, and capacitive devices require embedded probes. In addition, magnetostrictive probes may float and move. Furthermore, it would be even better if openings could be avoided at the bottom of the reactor. People are more interested in reactors without additional equipment at the bottom, and top type equipment can save time during installation, maintenance, calibration, and relocation. After Zui, chooseStainless steel reed tube level gaugeAt that time, it may not necessarily be better. The method that surveyors can use is to ask users to propose the performance that the instrument should have. Too many performance specifications are detached from reality and not based on real process requirements.
The stainless steel reed level gauge consists of a magnetic float, a hollow plug, a junction box, and several resistors inside. The main structure of the basic instrument is composed of stainless steel guide tubes, floats, flanges or threaded connectors, junction boxes, core plates, and other parts. When the liquid level or phase interface changes, due to the magnetic effect, the float equipped with magnetic steel rises and falls with the liquid level (interface) and moves up and down along the guide tube, causing the resistance inside the sensor to change linearly. The stainless steel reed tube level gauge uses an intelligent converter to convert the resistance change into a 4-20mA standard current signal, so that the liquid level position change can be converted into an electrical signal. At this point, the actual position of the liquid is displayed digitally on the display instrument to achieve remote detection and control of the liquid level.
The stainless steel reed tube level gauge includes a floating ball, a floating ball connecting rod, a gear shaft, a large gear, a small gear, a magnetic steel shaft, a connecting flange and its magnetic steel, a table body flange and its magnetic steel, a pointer shaft, a dial, and a pointer. A guide bracket is installed on the connecting flange, and an arc-shaped limit plate is installed on both sides of the floating ball connecting rod on the guide bracket to control the floating ball connecting rod to rotate between the two arc-shaped limit plates. It is also possible to elevate the watch chamber into an inflation chamber, which is equipped with an inflation nozzle and filled with inert gas after vacuuming. The advantage is that the floating ball will not sway left or right when it rises or falls, thereby improving the measurement effect and extending the service life; When the ambient temperature drops below 0 ℃, the stainless steel reed tube level gauge will not frost or freeze on the chamber glass, making it easy to observe.
Stainless steel reed tube level gaugeThe main tube is equipped with a set of reed switches and precision resistors When the magnetic float outside the tube changes up and down with the liquid level The dry spring located at the liquid level in the main tube is sequentially connected to change the resistance value of the sensor. The conversion circuit module in the junction box converts its resistance value into a 4-20mA current output.
