IMADA FB-300N FB-500N Mechanical Force Gauge 300N

Description

The IMADA FB-300N and FB-500N mechanical force gauges are precision analog instruments designed for high-repeatability tension and compression testing across demanding industrial environments. Built with original engineering from IMADA Co., Ltd., these push-pull gauges utilize a dedicated spring-balance measurement mechanism that operates entirely without electrical power. This design delivers zero-drift performance, complete immunity to electromagnetic interference (EMI), and safe operation in spark-sensitive or explosive atmospheres. Featuring an instantaneous switch for real-time tracking and peak-hold capture, the FB series is an essential tool for rapid quality verification on production lines and testing laboratories.

SYSTEM ARCHITECTURE AND TECHNICAL COMPATIBILITY
The FB series features a precision-machined rack-and-pinion transmission equipped with anti-backlash gearing to translate linear rod travel into dial pointer movement with minimal mechanical hysteresis. The internal spring pack is thermally stabilized to ensure measurement linearity across varying ambient temperatures. The rear chassis includes standard four-point M4 mounting patterns (30 mm x 145 mm spacing), ensuring seamless technical compatibility with IMADA manual test stands (SV, HV, KV series), motorized test benches (MX series), and universal automation fixtures.

CRITICAL APPLICATION SCENARIOS
The mechanical architecture of the FB-300N and FB-500N addresses specific testing demands where digital instruments are unsuitable or cost-prohibitive:
1. Hazardous and Explosive Environments: Completely intrinsically safe for use in chemical manufacturing, pyrotechnic assembly, and flammable solvent handling areas where electrical test equipment is restricted.
2. Automotive Wire Harness and Terminal Pull Testing: Rapid pass/fail validation of crimped terminal retention forces to verify compliance with industry tensile extraction standards.
3. Switch Actuation and Insertion Force Measurement: Precise verification of push-button tactile force, connector insertion and extraction forces, and automotive latch engagements.
4. Packaging and Material Strength Testing: Testing the puncture resistance, peel strength of heat-sealed medical packages, and burst strength of containers.
