1 Introduction
1.1 IND500x Overview
The IND500x represents the latest weighing technology from METTLER TOLEDO and is the most versatile
weighing terminal for hazardous area Zone1/21 and Division 1 applications.
The IND500x terminal is a high-performance single- or multiple-range weighing terminal designed for use with
analog load cells or high-precision IDNet and SICSpro scale interfaces. The IND500x delivers precision
measurement data from milligrams to tons in a single cost effective package that easily integrates into existing
systems.
IND500x is powered by an external power supply that converts high level AC voltage to intrinsically safe DC
voltages and is still suitable for installation inside the hazardous area.
Enhanced PLC and PC communication interfaces are available through easy to install safe area communication
modules. Internal and remote digital I/O options provide control for process applications such as filling. The
versatile IND500x can be upgraded with a variety of special application software packages that add
performance features where needed. These features make the IND500x the perfect match for nearly any
weighing application in many industries, including:
Pharmaceuticals
Milling
Specialty Chemical
