1.The constant value control instrument is an intelligent instrument that adopts a bus non external mode, with a simple structure and high reliability.
2.The constant value control instrument can be matched with a flow meter to measure the mass or volume of flow.
3.The constant value control instrument can be controlled by inserting parameters through the panel.
1.The EL-2000 series constant value controller has temperature compensation function, and the upper and lower limits of temperature can be set through the panel.
2.The EL-2000 series constant value controller has power-off protection function for parameters and is an ideal instrument for modern control.
Product Features:
Dimensions: 80x160x250, hole size: 76+1×152+1mm
There is a secondary parameter display, with commonly used parameters displayed at the first level. The secondary display can be accessed by entering a password through the panel, which is convenient, flexible, and confidential.
The upper and lower limits of temperature can be adjusted within the specified range, and the on-site adaptability is strong.
Adopt reliable power-off protection methods to ensure foolproof protection of parameters.
