Schenck Process INTECONT Tersus Weighing Instrument

Schenck Process INTECONT Tersus Compact Weighing Electronic Device: The Core of High Precision Continuous Weighing System

Accurate measurement of material flow rate, cumulative total amount, and process control are key to ensuring production efficiency and product quality in the continuous transportation and processing of bulk materials. Schenck Process, as a leading global provider of weighing and process control solutions, has launched the INTECONT Tersus series of compact weighing electronic devices. This series is designed specifically for weighing tasks in continuous production processes and can be seamlessly integrated with belt scales (MULTIBELT), solid flow meters (MULTITREAM), and Coriolis mass flow meters (MULTICOR) to provide high-precision and high reliability measurement and control functions.

This article is based on the original content of Schenck Process's official product catalog "VEG20650-1. pdf". It systematically organizes and deeply analyzes the equipment characteristics, working principles, weighing functions, technical parameters, selection and configuration, and application scenarios of INTECONT Tersus, providing authoritative and professional technical references for engineering design, system integration, and maintenance personnel.

Product positioning and application areas

1.1 Applicable Equipment Types

INTECONT Tersus is specifically optimized for the following three types of continuous weighing equipment:

Belt scale (MULTIBELT): By measuring the material load and belt speed on the belt, calculate the instantaneous flow rate and cumulative amount.

Solid flow meter (MULTISTARAM) (planned to be supported in 2012): uses the reaction force on the measuring chute when the material falls to calculate the flow rate.

Coriolis Mass Flow Meter (MULTICOR) (planned to be supported in 2012): Based on the Coriolis principle, it directly measures mass flow and is suitable for bulk materials such as powders and particles.

Working principle and core functions

3.1 Measurement principle (varies by device type)

Although the basic hardware of INTECONT Tersus is the same, its flow acquisition method varies depending on the connected mechanical system:

Belt scale: Collecting belt load (kg/m) and belt speed (m/s) through sensors, integrating and calculating instantaneous flow rate (t/h) and cumulative amount (t).

Solid flow meter: measures the reaction force generated by the impact of materials on the chute, and converts it into flow rate after calibration.

Coriolis mass flowmeter: Based on the Coriolis principle, it directly measures the torque and speed generated by the material in the rotating measuring tube to obtain the true mass flow rate.

3.2 Standard Features (applicable to all models)

Manual and automatic zero setting: Ensure long-term stability.

Full feed/trickle feed control: used for precise batch batching (full feed/drip feed control).
