Intelligent liquid level transmitter
Double flange liquid level transmitter
WS3051-DP-1199 double flange liquid level transmitter is our company to introduce foreign advanced technology and equipment to produce a new type transmitter. The key raw materials, components are derived from the import,and whole machine is assembled and tested strictly. The product has the characteristics of advanced design principles, complete varieties and specifications, easy to install and use, and so on. Because this model appearance completely integrates the most advantages of the two kinds of transmitter (Rosemount3051and Yokogawa EJA)is popular and widely used, allowing users to find everything fresh and new feeling, and directly replace traditional products and installation, strong versatility and ability to substitute. In order to adapt to the continuous improvement of the level of domestic automation and development, the series of product design is compact and delicate, more introduced with the HART field bus protocol intelligent functions. When liquid level transmitter with remote seal device, it becomes WS3051-DP-1199 double flange level transmitter, it still has the characteristics of differential pressure / pressure transmitter. Can communicate with the HART hand operator, through its setting, monitoring.
二、Operational principle
WS3051-DP-1199 double flange level transmitter is used to prevent the medium in a pipeline directly into the pressure sensor module in the transmitter, between it and the transmitter is connected by the capillary filled with fluid. Used to measure the liquid, gas or steam liquid level, flow and pressure, and then change it into 4 ~20mA DC signal output.
● The need to isolate the high temperature medium and transmitter.
● The measurement of medium has a corrosive effect in the transmitter sensor sensitive components.
● The measured medium solidification or crystallization due to environmental or temperature changes.
● The replacement of the test media needs to be strictly purification measuring head.
● Suspension of liquid or high viscosity medium.
● The measuring head must be kept clean and sanitary.
● The measurement of sealed pressure vessel.
1. Wide measuring range: 0-100m、-0.1MPa-0、0-(10KPa-20MPa)
2. Zero and span continuous adjustable
3. Reverse polarity protection and current limiting protection
4. Good impact resistance performance
5. High precision、High stability、High reliability
6. Special connection structure, easy maintenance
7. Applicable to occasions with higher requirements, comply with the requirement of measurement standard
8. Unique design makes the water hammer shock performance is good, long service life
9. Exquisite structure
10. Good freezing resistance
11.Using the two wire transmitter integrated structure, no moving parts, simple maintenance
12.Four digit LCD display. Hd backlight,easy to observe data at the scene
13.Intrinsically safe type and explosion proof type can be used for dangerous scene
