Abstract
The utility model discloses a high accurate digital display water level gauge. The utility model is designed on the float-type working principle and adopting the magnetic induction conversion method. The water level gauge is used in different areas with larger water level variation, can carry out measurement or central detection on the water level in a distant range, and is provided with a water level alarm device for over limit.
Description
The utility model belongs to field of measuring technique.
A kind of level measurement device is arranged in prior art, with reference to the Jap.P. this level measurement device of " openly speciallyying permit the clear 58-71420 of communique " be in flexible pipe, be equipped with several to electric contact, be subjected to the pressure effect of hydraulic pressure when flexible pipe, flexible pipe produces distortion, the conducting of electric contact auto-closing is connected by the relay of connecting line with the outside, makes the junction closure of relay, this level measurement device complex structure, the level measuring out of true.The utility model improves this level measurement device.
Implementation method is seen Fig. 1 water level gauge structural drawing
Fig. 2 circuit theory diagrams
The measured Rubber batten 6 of matter is every tongue tube 7 of 1 centimetre of installation, and tongue tube 7 will be staggered, and one 10 Ohmage 5 of each tongue tube 7 series connection vertically is installed.To install De Rubber batten 6 assemblys, pack into sealing and all good plastic tube 4 internal fixation of insulation, extension line 9 before plastic tube 4 sealings is connected with external digital indicator gauge 10.Annular float 3 is equipped with in the outside of plastic tube 4, and the inside of annular float 3 is surrounded by annular magnetic steel 2, and plastic tube 4 is installed in the location and sits on 1 and 8.
The anchoring filament 11 and 14 of lead-in wire 9 is housed on the top of plastic tube 4, and lead-in wire 9 is drawn by the O-ring seal 13 of the upper end of sealing cap 12.
When water level changes, annular float 3 also changes with the height of surface level, and tongue tube 7 is subjected to the influence of annular magnetic steel 2, and with the junction closure conducting of annular magnetic steel 2 corresponding tongue tubes 7, at this moment the analog quantitys of two lead-in wire 9 outputs change.The analog quantity input digit indicator gauge 10 of this variation, along with the variation of input analog amount, digital wash 10 shown digital quantities also change.
When needs water level spacing alarm or control, the positioned internal adjustment of digital wash 10, when the water level that changes arrived warning or control water level, warning was rung automatically or is controlled.
This water level gauge of the utility model can be installed under the various environment and use, and the wide range that sounds the depth of the water can reach 200 meters degree of depth, and the total length of plastic tube 4 can be decided by the place to use, and the number of applications of tongue tube 7 and resistance 5 is also along with changing.The precision height of this water level gauge of the utility model, its resolution is at 1 centimetre.
