linear displacement sensor (commonly known as electronic ruler) is an electronic component used to detect displacement. At present, it is widely used in plastic machinery to detect injection, mold opening and closing stroke, thimble and other actions. TTC-TOM electronic ruler is a well-known brand of TOM TECH CORPORATION U.S.A It has been registered by the Trademark Office of the State Administration for Industry and Commerce, allowed to be sold and used, and passed CE certification. At present, there are nearly 1 injection molding machine manufacturers in use, such as Nanhai Jiaming, Guanlan Dadicheng, Shenzhen Jianda, Guangzhou Bochuang, Huadu Liyuan, etc.; Hangzhou has Zhejiang Shen Da, Tenglong/Eurasia, Tailian, Huada, Terry, etc. Ningbo has Hengrun, GM, Yongtai, Haixiong, Sanshun (Hongyu), Xieli, Hongtian, etc. Others are Glen, LG, Fenxi, Yada, Huatian, Zhenda and so on. Its quality is stable and its price is low. The new generation of TOM electronic ruler has new functions such as laser anti-counterfeiting, anti-oil and anti-shock.

principle of electronic ruler

name: specifications and parameters of ultrasonic rangefinder: (1) overall dimensions: LxWxH 144x45x26mm (2) wavelength (λ)63-66nm (3) power Class II P <; 1mW CLASS IIIA P< 5mW (4) working current: I <: 4mA (5) Starting voltage: DC=2.3V (6) Working voltage: DC=9V (7) Working power supply: a 9V battery Function: * Accurate measurement of vertical distance from a certain point to a certain surface by ultrasonic wave. * You can choose metric system or English system for measurement and operation, or convert between these two systems. * 1 measured values, input numbers or operation results can be stored, and the stored data will be automatically saved after shutdown. * 6-digit calculation function can be performed. * The internal temperature is automatically compensated, and the measuring distance is not affected by the ambient temperature. * Laser can be used to guide the measurement, so as to measure more accurately.
