Injection Molding Clamping Force Measurement Sensor 100ton 50t 30 ton 20t 10ton

M16/M32/M40/M60 threaded Injection Molding Clamping Force Measurement Sensor FCM is made of high stiffness alloy steel based on foil strain gauge technology to deliver 2.0mV/V rated output proportional to the applied force.Pancake load cell FCM offers 0.5 ton / 1ton / 2 ton / 3ton / 5 ton / 7ton / 10 ton / 20ton / 25 ton / 30ton / 50 ton / 60ton / 100ton thirteen rated capacities to choose from. Compressive load cell FCM is suitable for both static and dynamic force measurement in tension and compression direction.Low profile structure makes it also suitable for in-line force monitoring.Clamp Force Sensor FCM is designed with a metric threaded hole running through the center of the transducer which can be used to mount attachments such as load buttons,eye bolts or other adapters for force loading,this makes spoke type load cells very adaptable to various cases, you may find pancake type load cell FCM applicable for force measurement in injection-molding machines, press machines and material testing equipment, weight measurement for tanks, vessels and hoppers, and so on. Custom made service is available if you need different dimensions or capacities.

A load cell sensor is a transducer that converts a load or force acting on it into electronic signal which is proportional to the load(or force) being applied.The measured load or force causes deformation of the measuring element(elastic body),the bonded strain gauge deforms accordingly which will cause the resistance change of the wheatstone bridge,under constant power supply,the output signal between Sig+ and Sig- will change proportionally,thus the load/force can be measured by measuring the output signal from the load cell.Pancake load cell FCM outputs millivolt signal which is normally within -30mV...+30mV,and signal amplification may be required for most applications,a load cell signal transmitter can be used to get 0-5V,0-10V or 4-20mA signal for easy data acquisition afterwards.Weight indicator can be used to display the measured value,load cell display FPT is integrated with high accuracy 24 bit Sigma-Delta ADC,sampling speed up to 960Hz,supports RS485 or RS232 communication port,can also output 0-5V,0-10V,0-20mV or 4-20mA amplified signal.

Specifications

Clamping force is the force needed to hold the mold together during injection and it is applied by the clamping unit of an injection molding machine. It may cause mold failure like air bubbles, cavities, wall cracks, etc. if the clamping force is not monitored and controlled properly.Forsentek load cells can be used to monitor the total clamping pressure, during plastic injection molding and die casting, the mold is clamped together to resist the rapid thermal expansion and contraction caused by the molten material filling the mold cavity. Flawed parts can be created if the mold is not kept properly clamped to resist thermal loading throughout the molding and casting process.To mitigate these thermal effects, Pancake Load Cells are placed at the clamp contact points, enabling the injection molding machine to monitor the clamping pressure in injection molding and adjust clamping forces accordingly

Output signal of load cell and amplifier:
Load cell output: = (Power supply * Rated output) * Load / Capacity
Rated output of Pancake Load Cell FCM is normally around 2.0mV/V.
Power supply of Clamping Force Load cell FCM is normally within 3-15V.
Load / Capacity is within 0-1.
So the output range of Universal Force Sensor FCM is normally within 0…+30mV.(-30mV…+30mV output for tension and compression force measurement.
Example one: Compression Load Cell FCM-30t with 2.0mV/V sensitivity powered by 5V DC, the output range is 0mV...+10mV.
Example two: Pancake Load Cell FCM-50ton with 2.0mV/V rated output powered by 10V DC,the output range is 0mV...+20mV.
The mV/V output from the wheatstone bridge sometimes can hardly be processed directly, a signal conditioner can be used with the load cell to deliver 0~5V, 0-10V or 4-20mA output.
Example one: Compression Force Load Cell FCM-100t working with amplifier FSC(0-10V)-24V,the Load-Voltage relationship will be 0-100ton compression force VS 0-10V output, which is linear regardless of the measurement error, 1V output corresponds to 10ton compression load, 2V output corresponds to 20ton compression load, and so on.
Example two: Pancake Load Cell FCM-50ton working with amplifier FSC(4-20mA)-24V,the Force-Current relationship will be 0-50ton compression force VS 4-20mA output, which is linear regardless of the measurement error, 4mA output corresponds to “0” load, 5.6mA output corresponds to 5ton compression load, 12mA output corresponds to 25ton compression load, and so on.
