The BHM is a high-precision, portable clamping force measuring instrument designed for testing the door clamping force of public transport vehicles (trains, high-speed railways, subways, buses). Equipped with a strain gauge force sensor, it delivers accurate, dynamic measurements (30N-500N) while tracking real-time test curves (time vs. force value). Its lightweight, durable design and PC data analysis capabilities make it ideal for on-site testing and quality control.
◆ Features
Dynamic & Portable Design: Compact, easy-to-operate instrument for on-site door force testing; tracks the entire test process in real time.
High Accuracy & Wide Range: Measures 30N-500N with ±1N precision (±3N deviation in 50-500N range); third-party calibration certificates available (fee-based).
Durable Construction: Load cell housing made of high-strength aluminum alloy (black anodized surface) with 500% overload capacity, shock resistance, and IP30 protection.
Data Analysis & Export: Connects to PC via proprietary software; analyzes test results/pressure curves and exports data to Excel format.
The measuring instrument is mainly composed ofload cell, handheld indicator andconnection cable. The load cell and the connection cable are connected and communicatedthrough the aviation plug, and the handheld indicator and the connection cable are connectedand communicated through the D-type 9-pin connector, which is fast and easy to connect.
