Product introduction

YWB230 input type liquid level transmitter adopts high performance pressure sensor as measuring element. Through pressure sensitive element, it can accurately measure the liquid static pressure which is directly proportional to the liquid level depth. After the special signal conditioning circuit of Zetian sensor, it is converted into standard signal output, so as to establish the linear relationship between output signal and liquid depth, and realize the accurate measurement of liquid depth. Due to the adoption of high-performance pressure sensor, special signal processing circuit, fully sealed submerged design, all stainless steel integrated structure without movable parts, reverse polarity protection and instantaneous over-current and over-voltage protection and other technologies and processes, the product has the characteristics of high cost performance, small size, vibration resistance, anti-RF interference, high reliability and good long-term stability. At the same time, the top stainless steel cap can be removed, which not only can protect the film, but also is convenient for maintenance and cleaning. In addition, the product adopts Zetian's latest secondary lightning protection design technology, which is very suitable for liquid level measurement in open air, mountain top and other places vulnerable to lightning strike.  

The output signal forms of YWB230 input type liquid level transmitter are various, analog signal output or digital signal output such as RS485 can be selected, junction box and field display can be selected, which can meet the needs of customers for liquid level measurement under different conditions.
