Pharmaceutical industry is an industry with long and complex production process and high product quality standard. There are many kinds of raw and auxiliary materials needed for each drug, and many raw materials and intermediates in the production process are flammable, toxic or corrosive, which put strict requirements on dustproof, explosion-proof, waterproof, sanitary and other instrumentation equipment.

Accurate and reliable process measurement is crucial for continuous and efficient operation of cement factory. Proper application of the most suitable on-site equipment is the key to the success of all automation projects. Many instruments, sensors and continuous weighing equipment that can be installed in ordinary processing factory are not suitable for the harsh environment encountered by the cement industry.

The instrument application in plastic industry is very extensive, and parameters such as temperature, pressure, level and flow need to be measured and controlled.

The instrument application in engineering road machinery industry includes level measurement and pressure measurement. The level meter 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.

The instruments in refrigerated air conditioning industry are widely used where temperature, pressure, liquid level and flow rate need to be measured and controlled. For example, the liquid level instrument can be used to detect the refrigerant position in the evaporator or condenser of the central air conditioning unit, and it can also detect the height of the refrigerant in the liquid storage of the bucket pump unit.
