Application of sensors in food industry: In the food industry,Process automation is increasing,For example, automation technology has occupied the packaging production line50%above,Extensive use of computer design and mechatronics control,The aim is to increase productivity,Improve flexibility and flexibility of equipment。Sensor is the key core of automation system,It has also been widely used in the food industry。
UseOsiconcept,A single product meets all light detection needs。In fact,Press as follows“self-learning”Mode button,Products are automatically optimized to meet application needs。 1、Direct detection of objects; 2、Direct detection with background suppression; 3、reflector(Reflector attachment)probe; 4、Optical receiver detection(Transmitter attachment for firing)。
The use factor mainly refers to the installation adjustment、Service and maintenance、Whether the maintenance and repair meet the technical requirements。Installation conditions are one of the first factors in use,Four row cylindrical roller bearings are often improperly installed, resulting in changes in the stress state between the components of the whole set of bearings,Bearings operate in an abnormal state and fail prematurely。Bearing mounting、Use、maintenance、Technical requirements for maintenance,The load on the running bearing、Rotational speed、Operating temperature、Vibration、Noise and lubrication conditions are monitored and checked,If an exception is found, find the cause immediately,Make adjustments,Get it back to normal。In addition,Quality of grease and surrounding medium、It is also important to analyze and test the atmosphere。
What are the functions of solid state relays Solid-state relay,Be abbreviated to“SSR”,It is a movement without machinery,Relays without moving parts,It is a new contactless switching device composed entirely of solid state electronic components,He uses electronic components(Such as high-power triode,Power field effect tube,Single-phase thyristor and bidirectional thyristor devices)Switching characteristics of。The name of the relay is used to make the device play a current protection role。

In recent years,Machine replacement has become a craze,The industrial robot market is hot。In order to improve the adaptability of the robot,Timely detection of the operating environment,A large number of sensing devices are applied to the robot,These sensors make robots work better,To enable it to perform complex tasks more fully。
Ultrasonic level sensor set non-contact switch,controller,The transmitter has three functions in one,Suitable for small storage tanks,The flexible design of ultrasonic level sensors can be used in integrated systems or as an alternative to float switches、Conductivity switches and static pressure sensors,It is also suitable for integrated applications of fluid control and chemical feeding systems,Ultrasonic level sensor for machine,The application of small storage tanks for brakes and other equipment is also a good choice,PVDFThe sensor can be applied to mud,Corrosive medium,Ultrasonic level sensors are widely used in various atmospheric pressure tanks,Process tank,Small tanks and small containers,Pump lift station,Waste water storage tank, etc。

Temperature relay and thermal relay difference Temperature relay is a relay that operates when the external temperature reaches a given value。The product is a contact induction sealed temperature relay,Have small size、Light weight、High temperature control precision,Extremely versatile。Thermal relays work on the principle that the current flowing into the thermal element generates heat,Deformable bimetallic sheets with different expansion coefficients,When the deformation reaches a certain distance,Just push the linkage into action,Disconnect the control circuit,Thus, the contactor loses power,Main circuit off,Realize overload protection of motor。Both play a protective role in the circuit。
