The instrument application in engineering road machinery industry includes level measurement and pressure measurement. Level transmitter for solids can be widely used in various process sections such as pre-mixed concrete complete equipment, concrete mixing plant, shield machine, road surface mechanical asphalt station, and plant-mixed heat regeneration equipment.

Rotary paddle level switch, radar level sensor, electrode level switch and capacitance continuous level sensor are used to measure and monitor the material position of the storage and production of the concrete mixing station and the asphalt station. The hydraulic system such as tuning fork switch, pressure transmitter and other instruments is used to protect the hydraulic system of shield machine.

It plays an important role in all aspects of the engineering road machine. Even in the dangerous environment of engineering machinery, it is realistic to ensure engineering safety, material cost control and level control operation, which enables automatic remote alarm, unattended operation, lower air volume loss and higher efficiency to be possible.
