Description​

The MARPOSS E78 is a high-precision measurement interface module engineered by Marposs—a global leader in industrial metrology and quality control solutions.Designed as the”data translation hub”between precision sensors(e.g.,touch probes,laser scanners,linear encoders)and manufacturing systems(CNCs,PLCs,quality management software),it converts raw sensor signals into actionable measurement data with micro-level accuracy.Unlike generic interface modules,MARPOSS E78 features ultra-low signal latency,multi-probe compatibility,and robust industrial design—making it indispensable for applications where real-time dimension monitoring,process deviation correction,and consistent part quality are critical to manufacturing efficiency and compliance.​

Application Scenarios​

A German automotive component manufacturer faced challenges in its camshaft machining line:Legacy measurement systems had 200ms data latency,leading to 5%of parts exceeding dimension tolerances(each batch of 100 defective parts cost

Technical Principles and Innovative Values​

Innovation Point 1:Ultra-Low Latency Data Processing.Unlike standard interface modules(200-500ms latency),MARPOSS E78 uses a dedicated signal processing chip to achieve<10ms latency—critical for in-process adjustment.A U.S.aerospace manufacturer used this feature to correct turbine blade machining deviations in real time,reducing dimension errors by 80%and eliminating post-machining inspection steps.​

Innovation Point 2:Multi-Sensor Fusion Capability.The module synchronizes data from up to 4 different sensors(e.g.,touch probe+laser scanner)to create a 3D part profile—avoiding the need for multiple interface modules.A medical device maker reduced equipment costs by 40%(replacing 3 single-sensor modules with 1 MARPOSS E78)and improved hip implant measurement accuracy by 25%.​

Innovation Point 3:Adaptive Temperature Compensation.Built-in sensors monitor ambient temperature(±0.1°C resolution)and adjust measurement data to counteract thermal drift.A Japanese semiconductor factory maintained±0.2μm measurement stability even as cleanroom temperatures varied by 5°C—far exceeding the±1μm stability of legacy systems.​

Application Cases and Industry Value​

Case 1:CNC Machining of Gear Components​

A Chinese gear manufacturer deployed MARPOSS E78 modules on 12 CNC hobbing machines to monitor gear tooth profile and pitch errors.The module’s 1MHz sampling rate captured细微cutting vibrations,while Ethernet connectivity sent real-time data to the factory’s MES system.Before deployment,gear rejection rates were 4.2%(due to inconsistent tooth spacing);post-deployment,rejection rates dropped to 0.5%,saving

Case 2:Medical Device Implant Measurement​

A U.S.orthopedic implant manufacturer used MARPOSS E78 to inspect hip implant femoral heads(tolerance:±5μm).The module’s±0.1μm accuracy and laser scanner compatibility ensured precise measurement of spherical geometry,while temperature compensation counteracted heat from cleanroom lighting.Before deployment,manual inspection required 5 minutes per implant(300 implants/day);post-deployment,automated measurement reduced time to 30 seconds per implant(600 implants/day),cutting labor costs by$120,000 annually.The module also generated digital audit trails,simplifying FDA compliance inspections.​
