SN3051 Intelligent Pressure/Differential Pressure Transmitter

overview

The SN3051 intelligent pressure/liquid level transmitter is an intelligent field instrument developed and designed by our company, drawing on foreign experience and utilizing fully isolated circuit technology.
The key raw materials and components are all imported brands, and the whole machine has undergone strict assembly and debugging. This product features advanced design principles, complete variety and specifications, and easy installation and use. It can perfectly replace the currently popular imported brands in China.
Due to the adoption of a fully isolated circuit design, the stability and anti-interference ability of the entire machine have been greatly improved.
In addition to the three basic functions of adjusting zero position, range, and zero pressure fine adjustment of other transmitters, it also has functions such as zero point migration, setting display quantities, linear and square root conversion, setting damping time, and fixed current output testing.
The transmitter can modify parameters through communication software or a handheld device.
