Advantages of Mettler Toledo IND331xx explosion-proof weighing instrument compared with ordinary type

　　1、 Introduction to the advantages of the IND331xx explosion-proof weighing instrument compared to the IND331 weighing instrument in Mettler Toledo

IND331xx is Mettler Toledo IND331Weighing instrumentThe N-type explosion-proof model has been comprehensively improved on the basis of the IND331 instrument, including the shell, wiring device, introduction device, insulation dielectric strength, electrical clearance, and many other aspects. Optional IND331xx panel type and IND331xx dustproof type.

IND331xx has been comprehensively improved and improved to be an explosion-proof weighing display controller suitable for hazardous environments in Zone 2/22.Mettler Toledo weighing instrumentIND331xx can be widely used in paint and ink, pesticide and fertilizer, pharmaceutical, tobacco, essence and spice industries. Reliable performance, practical interfaces, simple calibration, convenient parameter settings, and system backup make weighing display, constant value control, weight sorting, and flow monitoring in hazardous areas more convenient and efficient.
　

　　2、 Reliable performance of IND331xx weighing instrument

1. Outstanding anti-interference ability, effective overcurrent protection, and more stable and reliable operation

2. Up to 100000 display divisions, providing more accurate weighing results

3. 50Hz weight comparison rate ensures higher control accuracy

4. OLED dot matrix display screen, lower power consumption, clearer reading

5. Add 24V DC power supply mode, with more power supply options available

　　3、 Practical interface for IND331xx weighing instrument

1. PLC interface

Supports PLC interfaces such as Profibus DP, 4-20mA analog output, AB RIO, DeviceNet, etc., making it easy to embed into various industrial control systems.

2. I/O interface

-2 in 4 out I/O interface

-Input interface for photoelectric isolation (configurable for active and passive users), OC gate output.

3. Communication interface

RS232 and RS485 (optional) serial ports support multiple serial output formats and can be connected to external devices such as secure area printers, computers, and large screens.

　　4、 Simple calibration

1. AlFREETM calibration free technology: In industrial environments where traditional weight calibration is difficult, using CalFREE allows calibration without the need for weights, bringing great convenience to on-site debugging.

2. StepCALTM step-by-step substitution method calibration: With the help of substitutes, precise calibration of large capacity storage tanks can be completed with only a small amount of weights.

3. Add remote calibration technology for PLC and InSiteTM PC tools, which can easily calibrate the scale even remotely, using PLC or InSiteTM PC tools provided by Mettler Toledo.

　　5、 Convenient parameter settings and system backup

1. InSiteTM PC Configuration Tool

Remote monitoring, parameter configuration, and program updates can be achieved through serial ports.

2. SD memory card

Plug and play enables easy system backup and recovery, as well as one-time setup of multiple instruments.
