Tuning Fork Liquid Level Switch Applied in Glue Level Measurement Recently, a Shenzhen composite material company reported that Jiwei Ring-11 tuning fork liquid level switches had good performance in the measurement of glue level. Different from water, alcohol and beverages, glues have poor fluidity, so the level measurement has always been a difficult problem in the field. Measurement difficulties of glue The viscosity of water is at 27 ℃ is 1cps, but the viscosity of glues is generally greater than 300cps, and even higher than 10000cps. Generally, the viscosity decreases with temperature rising. On the contrary, the viscosity rises when temperature decreasing. Floating level indicator, float level gauge, RF admittance liquid level switch and photoelectric switch are not applicable in glue level measurement. The reasons and difficulties are as following: 1. Easy to hang-up, resulting in false alarm; 2. Need to clean the probe frequently in time, or the glue can be harder and stuck on the probe; 3. Some glues are flammable and explosive, so the sensors are required to have explosion-proof approvals.

To convince the clients, Jiwei brought samples to test the glue level on site. To further test the performance of Ring-11 liquid level switch, the clients purchased one and tested it for a period. After several months of test trial, the good performance of Ring-11 won high praise from the clients. Advantages of Ring-11 liquid level switch Because the viscosity, most liquid level sensors cannot meet the measuring requirements. But why Ring-11 is able to measure? 1. Ring-11 liquid level switch is a highly reliable control switch specially used for liquid level measurement. Based on the fork resonant...
