METTLER TOLEDO IND245 Weighing Indicator

Overview

The METTLER TOLEDO IND245 is an industrial-grade weighing indicator engineered for high-reliability integration into diverse weighing systems—including platform scales, vehicle scales, bench scales, and animal weighing stations. Designed as a direct successor to legacy models such as the 8142Pro and Kingbird Plus, the IND245 implements a modular architecture with enhanced signal processing, real-time firmware responsiveness, and extended environmental resilience. It operates on the fundamental principle of analog-to-digital conversion of load cell mV/V signals, supporting both analog (0–20 mA, 4–20 mA) and digital (RS232/RS485, Ethernet) input protocols. Its dual-power capability—AC mains (100–240 VAC) or rechargeable NiMH battery—enables uninterrupted operation in fixed and semi-mobile environments, making it suitable for GLP-compliant production floors, logistics hubs, agricultural weighbridges, and retail back-office applications requiring audit-ready traceability.

Key Features

• Configurable IP rating options: IP44 (splash-resistant) or IP66 (dust-tight and high-pressure water jet resistant), certified per IEC 60529
• Triple-mount flexibility: desktop, pillar-mounted, or wall-mounted installation with standardized bracket interfaces
• Backlit LCD display with adjustable brightness and auto-dimming logic to maintain readability under variable ambient lighting (e.g., warehouse daylight vs. low-light loading docks)
• Intelligent power management: programmable auto-shutdown and backlight timeout; up to 30 hours of continuous operation on full NiMH battery charge
• Dual expansion slots supporting hot-swappable communication modules—including isolated RS232/RS485, 20 mA current loop, USB host/device, Ethernet (TCP/IP, Modbus TCP), Bluetooth 5.0, and Wi-Fi 802.11 b/g/n
• Isolated serial interface option minimizes ground-loop interference and protects connected PLCs or PCs from voltage surges during industrial data exchange
• Integrated digital I/O module (optional) enables direct control of external relays, lights, or printers without intermediate controllers

Sample Compatibility & Compliance

The IND245 is compatible with standard analog load cells (mV/V output), digital load cells compliant with METTLER TOLEDO’s POWERCELL® or IND570 protocols, and third-party sensors meeting OIML R76 and NTEP Class III/III L accuracy requirements. It supports calibration traceability to national standards via internal calibration routines and external weight verification workflows. Firmware complies with ISO/IEC 17025 documentation practices for measurement uncertainty estimation and supports user-defined audit trails for critical parameters (e.g., calibration date, zero tracking threshold, filter settings). Optional configuration lockout and password-protected admin mode align with FDA 21 CFR Part 11 requirements for electronic records and signatures in regulated manufacturing environments.

Software & Data Management

Data exchange is facilitated through METTLER TOLEDO’s File Transfer Utility (FTU), enabling bidirectional synchronization of configuration files, label templates, and diagnostic logs between the IND245 and Windows-based engineering workstations. The indicator supports XML-based template editing for label printing (via integrated thermal or serial printers), allowing users to define dynamic fields—including weight, tare, ID, timestamp, operator code, and pass/fail status—for compliance with GS1, EAN/UCC, and internal ERP labeling standards. Built-in transaction logging stores up to 10,000 entries with timestamps, and maintenance diagnostics generate automated reports detailing sensor stability, zero drift, excitation voltage variance, and communication error rates—exportable via USB or Ethernet for root-cause analysis.

Applications

• Vehicle Weighing: Supports temporary ID (bidirectional) and permanent ID (unidirectional) modes for axle-load and gross-vehicle-weight capture in quarry, waste transfer, and agricultural transport operations
• Checkweighing: SmartTrac™ graphical display provides Under/OK/Over status with configurable tolerance bands and statistical process control (SPC) indicators aligned with ISO 2859 sampling plans
• Counting: Implements two sampling workflows—tare-first then sample, or sample-first then tare—with automatic average piece weight (APW) calculation and batch count validation
• Animal Weighing: Configurable sampling window (1–60 seconds) computes moving-average weight for single or group animals, suppressing transient motion artifacts common in livestock handling
• Peak Hold: Captures and archives maximum, minimum, and mean peak values across multiple cycles—critical for tension testing, impact load monitoring, and packaging compression analysis
• Label Printing: Integrates with Zebra, SATO, and Avery Dennison printers using customizable ZPL/EPL or ESC/POS command sets; templates support barcode symbologies (Code 128, QR, DataMatrix)

FAQ

Does the IND245 support NIST-traceable calibration procedures?
Yes—the device includes built-in calibration wizards that guide users through multi-point linearity verification and span adjustment, with optional certificate generation referencing NIST-traceable weights.
Can the IND245 operate in hazardous locations?
No—it is not intrinsically safe or ATEX/IECEx certified; however, its IP66-rated enclosure makes it suitable for washdown and outdoor industrial environments.
Is firmware upgrade supported over Ethernet or USB?
Yes—firmware updates are delivered via signed .bin files through FTU or direct drag-and-drop onto the device’s internal storage when connected via USB mass-storage mode.
What is the maximum number of user-defined print templates supported?
Up to 16 label templates can be stored internally, each editable offline using METTLER TOLEDO’s Label Designer software and deployed via FTU.
Does the IND245 meet electromagnetic compatibility (EMC) standards for industrial use?
Yes—it conforms to EN 61326-1:2013 (industrial environment) for immunity and emissions, including surge, ESD, and fast transient burst testing.
