The drop-in level gauge is based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid. It is made of advanced isolation diffused silicon sensitive components or ceramic capacitive pressure sensitive sensors. Convert static pressure into electrical signal. After temperature compensation and linear correction. A pressure sensor that is converted into a standard electrical signal (usually 4-20mA/1～5VDC) to measure liquid level. It can also be called “static pressure level gauge, level transmitter, level sensor, water level detector”
The sensor part of the throw-in hydrostatic level transmitter can be directly thrown into the liquid. The transmitter part can be fixed with flange or bracket. It is extremely convenient to install and use. The height from the end of the water level gauge to the water surface can be accurately measured by directly putting it into the container or water body. And the water level value is output externally through 4-20mA current or RS485 signal.
304 stainless steel shell-thick shell. Anti-corrosion and long life, adapt to a variety of working conditions. 304 stainless steel, as a kind of widely used steel, has good corrosion resistance and heat resistance. Low temperature strength and mechanical properties. It has good hot workability such as stamping and bending, and it is corrosion resistant in the atmosphere.
Intelligent circuit-anti-interference, good stability to ensure correct signal transmission. Rectangular circuit board design. It can be well laid out on the circuit board regularly. Install circuit components. Effective use of limited space for heat dissipation. Ensure the stability, anti-interference and service life of circuit components.
Multiple output methods-support 4-20mA (default), RS485 (optional), NB-IOT can be customized according to needs. If you need NB-IOT, please contact customer service.
45°inclined pressure hole——45°cut surface design. Effectively reduce the abrasion of the shell caused by impurities at the bottom of the liquid. Allow the bottom pressure of the liquid to enter the pressure hole smoothly. Punching resistant design pressure hole. The diameter is 3MM. Anti-blocking, four-hole multi-directional sensing of pressure.
Laser marking-powerful manufacturers, all use laser marking. The sensor information can be imprinted on the surface of the shell for a long time without falling off. In order to save costs, Xiaoguangjia adopts self-adhesive stickers. Long-term liquid immersion will cause discoloration and fall off. Lost sensor information. Therefore, self-adhesive stickers are rejected.
Waterproof PVC lead-This sensor adopts high polymer PVC waterproof lead. The material is thick, wear-resistant, aging-resistant, and has a long life.
Air guide hole design-special note: Do not immerse the air guide hole and shielding parts in water. Outdoor installation can be folded into a semi-circular air hole vertically downwards. Do not use tape to plug the air guide hole when the signal line is lengthened. When this hole is blocked, the water level will rise or fall, and the meter value will not change with the change of the water level.
