TW8 Railcar Door Force Measurement (DFM) system is an excellent tool for measuring and evaluating the side door closing force of passenger car body on rail vehicles such as light rail/tram, metro, suburban, trunk rail and high speed rail. It conforms to the test requirements of the door clamping force of the relevant industry regulations. Through resistance strain type force sensor, electric door force gets display and measurement, to meet the highest measurement accuracy and operating standards. The weighing cell housing is made of high-strength aluminum alloy with a black anodized surface, which is light, resistant to environmental factors and has maximum impact resistance. The interior of load cell is built with high-quality, durable controls, 500% overload capacity and impact resistance.
