Pressure Controller LN10-300
Pressure Controller (Low Range)
Product Applications
Applications: semiconductor process, gas and liquid chromatograph, steam pressure control in MOCVD process, gas pressure protection control in extrusion molding process, autoclave/reactor pressure control, etc.
Second, product application
The LN10 pressure controller can be equipped with an integrated control valve or a split control valve. It is a proportional solenoid control valve with ultra-fast and smooth control. We have different series of control valves for specific applications. Standard direct-acting valves are used for conventional applications and pilot valves are used for high flow rate applications.
Product Overview
The LN10 series pressure controller/gauge is a straight-through design with a measurement range from 100KPa to 10MPA (absolute and gauge). Differential pressure transmitters are also available. This series of instruments has high accuracy and good repeatability, and is divided into two types: front pressure control and back pressure control.
The LN10 series comes standard with a piezoelectric diaphragm pressure sensor and digital circuit board to provide high-precision, stable, and reliable pressure measurement and control. This basic digital PC board has all the basic functions you need for measurement and control. In addition to the standard RS485 output signal, the LN10 also provides analog I/O signals.
