In-Process Force Measurement system is easy to retrofit
Retrofitting old machines for in-process force measurement can present many challenges. Some of these include sensor integration and high production cycle rates. Sometimes the existing sensing system or PLC cannot respond fast enough for reliable performance. PCB Piezotronics has developed an effective system for these applications with the new In-Process Force Measurement system, which consists of a Series M240 ICP Strain Sensor and Model 410A01 ICP signal conditioner, featuring Peak Hold.
The Peak Hold feature of the in-process measurement system allows older PLC systems to stay in synch with high-speed production cycles. The Model 410A01 ICP signal conditioner captures and holds the peak reading until a PLC can scan for the value. A simple solid-state relay resets peak hold value, ensuring high-reliability force measurement for fast machine cycles.
The simple force measurement system is intended for use in a wide range of process monitoring and control applications. The system comprises a bolt-on sensor and DIN rail mounted module which can be installed and running in a matter of minutes. Its high-resolution analogue output (0-5VDC) can be directly correlated to units of force. This system is suitable for monitoring and verifying stamping, crimping, press-fit, riveting or other assembly force fabrication applications, including material presence and misalignment.
