Excellent reliability
The requirements for operational safety and reliability of online analysis systems, especially online process analysis instruments, are increasingly increasing. In the EcoLine seriesWTW fully considers the protection against electronic electromagnetic interference in the listed products: it has built-in rough and good lightning protection, resistance to EMI and RFI interferenceThe functions of disturbance, input and output insulation make the LF 170 monitor safe and reliable.

Programmable relay function
Users can set two sets of control/alarm relays as NC or NO contacts. The relay function can be assigned by the user, and the relevant functional parameters can be determinedSet up in the submenu. When the control mode of the relay is selected, the instrument requires the input of upper and lower control points and then the input of hysteresisAnd the delay time.
The hysteresis defines the symmetrical error range of the control point to delay triggering the relay.

Good human-machine communication
The operation menu is simple and clear, and users can easily set up and operate the instrument through menu prompts. Instrument software menuDivided into three levels.
The instrument is easy to operate, and calibration and testing can be completed with just two buttons. There are two sub menus of functions under the user menu, one isCON menu: Users can set the basic functions of the instrument; The other is the PAR menu: setting instrument function parameters. The instrument is password protected to prevent unauthorized personnel from changing settings. To prevent operator errors, the instrument must be set up one by oneConfirm all settings before exiting.
