Fault in Concrete Batching Machine Weighing

Overflow line fault of control instrument said values, display an error message, weighing signal suddenly or disorderly jump, there are two reasons:

Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:mobile ready mixed concrete plant,concrete batching plants,concrete mixer,blocking making machine,concrete pump,etc.

1. the connection between the sensor and control meter circuit breakers.The external fault is mainly was caused by improper installation and use concrete block making machine, if use multi-meter to check sensor input and the output resistance, resistance are normal.The cause of failure is: wire broken, cause break;Cable is loose or not use soldering welding joint, etc.

2. the sensor itself quality has a problem.Show the sensor input, output, resistance to change.Sensor input resistance is normally 400 Ω + 10 Ω, the output resistance of 350 Ω Ω plus or minus 3.Sensor is the main fault, terminal or lead solder joints fall off;Zero temperature compensation or sensitivity to temperature sensor to compensate the resistance virtual soldering or desoldering.Internal chip sensor seal is bad, be affected with damp be affected with damp.
