4-20mA High Accuracy RS485 GML601-C High Precision Small Blind Spot Ultrasonic Level Transmitter
GML601-C High Precision Small Blind Spot Ultrasonic Level Transmitter
GML601-C high precision small blind spot ultrasonic level transmitter is developed by our company for small blind zone, high precision and small space working condition control. China’s first ultrasonic ranging product with a blind zone of less than 0.06m and an accuracy of ± 1mm (has won the National Science and Technology Innovation Fund Project Award, Chongqing High-tech New Product, and Chongqing Key New Product). The shell is made of ABS engineering plastic waterproof shell, the probe part is PP or stainless steel, the shell is small and very sturdy; the transparent main cover is designed for easy observation and display. The main chip adopts imported industrial-grade
single-chip microcomputers, digital temperature compensation, and ultra-wide voltage input voltage regulators, including dozens of related application-specific integrated circuits, to make the product performance more stable and more reliable. It has strong anti-interference ability. It can set the upper and lower limit nodes and online output adjustment arbitrarily through the host computer software. It can choose analog quantity, switch quantity and RS485 output, which is convenient to interface with related facilities. It has high reliability, no pollution, stable performance, and can meet most liquid level and material level measurement requirements without contacting industrial media. It completely solves the shortcomings of entanglement, blockage, leakage, medium corrosion and inconvenience caused by traditional measurement methods such as pressure, capacitance, and float. Therefore, it can be widely used in various fields related to material level and liquid level measurement and control. This product has been inspected and approved by the national authority. This product complies with the national standard requirements of GB3836.1-2010 and GB3836.4-20010. The explosion-proof mark is ExiaIIBT4Gb.
