FST load cells offer wide capacity ranges for both mobile crane and stationary crane, acquire the real time monitoring of weighing data, and feedback to control system, guarantee safe operation of load and unload containers. MH position sensors acquire the real time monitoring for cylinder positioning, guarantee safe displacement of each moving parts. PT08 Pressure transmitters acquire the real time monitoring of pressure value of hydraulic oil in the system, guarantee hydraulic pump will work properly, if pressure range exceed the specified limit value, pressure transimitters will send the alarm signal to the system in time.

Production Process of load cellLoad cell instruments aim to highlight the actual mass of a material. They are produced based on the principles of mass measurement under fluid pressure, elasticity, magnetic effect, piezoelectric and zero environments. The two basic components of a load cell are the s

The more gauges inside the load cell, the more sensitive the cell is in recording and monitoring variance in measurement. When calculating the potential capacity of a load cell, manufacturers consider: the maximum force value, the dynamics of the system (i.e. frequency response), the effect that placing the transducer in the force path will have and the maximum extraneous loads that the load cell will handle.

The main application of strain gauges is the manufacture of force and pressure transducers, particularly load cells. A load cell is a type of transducer that measures the mechanical load on an object by converting it to readable electronic signals. They are used in various industries such as automation, process control, biomechanics, equipment monitoring, building integrity analysis, bulk material weighing, testing, and quality control.

Modern load cells work using a combination of the Wheatstone bridge equation and the strain gauge. The Wheatstone bridge equation was developed in 1833 by Samuel Hunter Christie, and improved upon and popularized in 1843 by Sir Charles Wheatstone. Wheatstone bridge circuits illustrate the concept of a difference measurement. Today, load cells are usually made up of four strain gauges in a Wheatstone configuration.

How to choose a load cell 1. Consider the load input direction. 2. Consider the object to be weighed: capacity, resolution, shape. 3. Consider the environment the Load Cell will operate in. 4. Consider the desired accuracy, error ratings, and ease of calibration. 5. Select the load cell type for the application.

Higher voltages through the resistive strain gauges (which comprise the Wheatstone bridge) will cause more current to flow and heat the strain gauges. The cell body acts as a heat sink to keep the gauges cool. If the maximum rated excitation voltage is exceeded, the heating will cause signal perturbation or gauge failure. Additionally, in battery operated devices, high excitation voltage (and thus, current) will cause the battery to deplete much faster than with lower excitation voltages through the circuit.

① Creep Recovery The change in no--load output occurring with time after removal of A load which had been applied for a specific period of time. Usually measured over a specific time period immediately following removal of rated load and expressed as a percent of rated output over a specific period of time. ② Deflection The change of length along the primary axis of the load cell between no--load and rated load conditions. ③ Drift A random change in output under constant load conditions.

① Ambient Conditions Humidity, pressure, temperature, etc. of the medium surrounding the load cell. ② Ambient Temperature The temperature of the medium surrounding the load cell. ③ Angular Load Eccentric A load applied eccentric with the primary axis at the point of application and at some angle with respect to the primary axis.

How to select the appropriate sensor When we provide sensing solutions, it is very important to choose the right products. There are so many kinds of sensors. Once the selection is not good, it will bring a lot of issues to the application.
