IMADA DTX2-40B – Digital Screw Cap Torque Tester | DTX2 Series
Engineering Background
IMADA Co., Ltd. (依玛达株式会社) has been a global authority in force and torque measurement instrumentation since 1947. The DTX2 series represents IMADA’s flagship digital torque meter platform, engineered specifically for closure torque verification in regulated manufacturing environments. The DTX2-40B variant, rated at 500 N·cm full scale, is the industry-standard choice for medium-range cap torque validation across pharmaceutical, food & beverage, and cosmetics packaging lines.
Product Positioning
This unit — cross-referenced as P/N 810-495659-504, 0190-34636, and PV2A015SMT1PA0-C2 — is a precision handheld digital torque gauge designed for both application torque (closing) and removal torque (opening) measurement of screw caps, child-resistant closures, and tamper-evident seals. It delivers traceable, data-loggable torque readings that satisfy GMP, ISO 8317, and USP closure integrity requirements.

Proven Application Environments
- Pharmaceutical Packaging: Closure torque validation per USP and ISO 8317 for child-resistant and senior-friendly closures
- Food & Beverage: PET bottle cap, glass jar lid, and aluminum closure application/removal torque QC on filling lines
- Cosmetics & Personal Care: Pump dispenser, flip-top, and screw cap torque consistency verification
- Automotive Components: Small fastener and connector torque audit in sub-assembly stations
- R&D Laboratories: Closure design validation, material fatigue studies, and torque-angle correlation testing
- Contract Manufacturing: Incoming inspection and outgoing QC for closure-intensive production runs
Engineering Advantages
- Bidirectional Measurement: Simultaneous CW (application) and CCW (removal) peak capture eliminates instrument changeover between test modes
- High-Speed Sampling (1,000 Hz): Captures transient torque spikes that analog gauges miss, critical for ratchet-style child-resistant closures
- RS-232C Data Output: Direct integration with SPC software (e.g., IMADA DATA-LINK, National Instruments LabVIEW) for real-time statistical process control
- Multi-Unit Display: Eliminates conversion errors across international engineering teams working in mixed unit environments
- Traceable Calibration: Factory-calibrated with JCSS-traceable standards; calibration certificate included
- Ergonomic Handheld Form Factor: Reduces operator fatigue during high-volume sampling; compatible with bench-mount fixture (sold separately)
System Architecture & Signal Flow
The DTX2-40B employs a strain-gauge torque transducer integrated into the instrument body. Applied torque deforms the sensing element, generating a differential voltage signal that is amplified, digitized at 1,000 Hz by an internal 24-bit ADC, and processed by the onboard microcontroller. Peak values are latched in non-volatile memory and displayed on the LCD. The RS-232C port streams real-time and peak data at 10 Hz to external logging systems. The instrument auto-zeros on power-up and supports manual zero-reset between measurements to compensate for fixture preload.

Technical FAQ
Q: What is the difference between DTX2-40B and DTX2-40?
A: The DTX2-40B includes bidirectional (CW + CCW) peak measurement and RS-232C output as standard. The base DTX2-40 is unidirectional without data output.
Q: Can the DTX2-40B be used on a motorized test stand?
A: Yes. The instrument is compatible with IMADA MX2 and MX-500N motorized test stands via the RS-232C trigger input for automated cycle testing.
Q: Is recalibration service available?
A: Yes. Konmask.com coordinates IMADA-authorized recalibration with JCSS-traceable certificate issuance. Typical turnaround is 10–15 business days.
Q: What closure diameter range is supported?
A: The standard jaw set accommodates closures from 20 mm to 120 mm diameter. Custom jaw sets are available for non-standard closure geometries.
Q: Does the unit comply with 21 CFR Part 11?
A: The DTX2-40B hardware supports data output for compliant logging systems. Full 21 CFR Part 11 compliance requires integration with validated SPC/LIMS software on the host PC.
