Small blind area ultrasonic level gauge

RSTMH-T series of high precision small blind area ultrasonic object (liquid) position instrument is specially developed for small blind area, high precision, small space of the working condition measurement and control. The case is ABS engineering plastic waterproof case, the probe part is PP or stainless steel, the case is small and quite strong; Transparent host cover design for easy observation and display. The main chip adopts imported industrial-grade single chip microcomputer, digital temperature compensation and ultra-wide voltage input voltage regulator and other dozens of relevant special-purpose integrated circuits, so that the product performance is more stable and reliable. It has strong anti-interference, can be arbitrarily set upper and lower limit nodes and online output adjustment through the upper computer software, can choose analog quantity, switching quantity and RS485 output, convenient and related facilities interface. It has high reliability, no pollution, stable performance, no contact with industrial media can meet most of the liquid level, material level measurement requirements. The shortcomings of traditional measurement methods such as pressure type, capacitance type and float type, such as winding, blockage, leakage, dielectric corrosion and inconvenient maintenance, etc., have been completely solved. Therefore, it can be widely used in various fields related to material level and liquid level measurement and control.
