GML601-B 0-2m range small blind high accuracy 4-20mA water oil tank ultrasonic level transmitter
Product Overview
GML601-B high-precision small dead zone ultrasonic material (liquid) position meter is developed by our company for small blind area, high precision and small space working condition measurement and control. The first domestic ultrasonic measuring range 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, Xi'an High-tech New Product, and Xi'an Key New Product). The outer casing is made of ABS engineering plastic waterproof casing. The probe part is made of PP or stainless steel. The casing is small and quite sturdy. The transparent main cover is designed for easy observation. The main chip adopts imported industrial-grade single-chip microcomputer, digital temperature compensation and ultra-wide voltage input voltage regulator and other dozens of related ASICs to make the product performance more stable and reliable. It has strong anti-interference ability, can be set by the host computer software to set the upper and lower limit nodes and online output adjustment, select analog, switch and RS485 output, convenient 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 such as winding, clogging, leakage, medium corrosion, and inconvenience caused by traditional measuring methods such as pressure type, capacitance type, and float type. Therefore, it can be widely used in various fields related to material level and liquid level measurement and control. This product has been tested and approved by the national authority. This product meets the requirements of GB3836.1-2010 and GB3836.4-20010 national standards. The explosion-proof mark is ExiaIIBT4Gb.
