Product Applications
I. Hydraulic and Lubrication System
Application fields
Oil tank temperature monitoring: Installed on the side wall of the hydraulic oil tank or lubricating oil tank, it monitors the overall oil temperature of the system.
Return oil pipeline temperature monitoring: Directly monitor the temperature of the hot oil returned after the actuator works, reflecting the real-time thermal load of the system.
Key component temperature monitoring: Installed on pumps, motors, and bearing housings to monitor their local working temperatures.
Cooler efficiency monitoring: Install them respectively at the inlet and outlet of the cooler, and determine the working condition of the cooler through the temperature difference.
Function and Role
Real-time monitoring and display: Precisely display the oil temperature on the HMI, providing the operator with the primary parameter of the system status.
Intelligent temperature control
Control cooling system: When the oil temperature rises to the set value, the fan or water-cooling valve is automatically started/adjusted.
Control heating system: When starting at low temperatures, the heater is automatically connected to ensure that the oil is within the optimal viscosity range.
Safety interlock protection: Achieve multi-level protection (e.g., alarm at 60°C, shutdown at 70°C) to prevent oil deterioration, seal failure and equipment damage caused by excessively high oil temperature.
Predictive maintenance: By analyzing temperature trends, it diagnoses early faults such as leaks within the system, decreased cooler efficiency, and bearing wear.
Ii. New Energy Industry (Key Points: Energy Storage, Wind Power, Hydrogen Energy)
Application fields
Electrochemical energy storage system
Battery pack (BMS) : It directly monitors the surface temperature of battery cells or terminal posts and is the core of battery thermal management.
PCS/ Combiner cabinet: Monitors the temperature of power converters and IGBT heat sinks.
Fire protection and environmental monitoring: Monitor the ambient temperature of the battery compartment.
Wind power generation
Gearbox lubrication system: Monitor the temperature of the lubricating oil.
Generator windings and bearings: Monitor the temperature of the generator before and after cooling and the temperature of the bearings.
Pitch/yaw system: Monitor the oil temperature of the hydraulic system.
Hydrogen fuel cell
Stack cooling system: Precisely controls the working temperature of the stack.
Air compressor: Monitor the temperature of the air compressor and its lubrication system.
Hydrogen circulation system: Monitor the ambient temperature of key components.
Function and Role
Thermal safety management: Preventing battery thermal runaway is the first line of defense for the safety of energy storage systems. Control the thermal management system (air conditioning, liquid cooling pump, heating film) through temperature data.
Life and efficiency optimization: Ensure that batteries, fuel cells, and wind power gearboxes operate within the optimal temperature range, enhance energy efficiency, and extend service life.
Power limiting and derating: When the temperature is too high, the BMS or controller will limit the charging and discharging power to protect the equipment.
Fault warning: Provide early warnings for key faults such as overheating of generator bearings and abnormal oil temperature in gearboxes.
Iii. Photovoltaic Industry
Application fields
Photovoltaic inverter
IGBT/MOSFET heat sink: Directly installed on the heat dissipation substrate of the power device, it is used for overheat protection and cooling fan control.
Dc busbar/inductor: Monitors the temperature of the high current path.
Internal ambient temperature of the box: Used for the start and stop control of the air conditioner or fan in the cabinet.
Tracking bracket system
Drive motor/reducer: Monitor its working temperature to prevent overload damage.
Function and Role
Inverter overheat protection: When the temperature of power devices is too high, it triggers load reduction or shutdown to prevent device burnout.
Intelligent cooling control: Precisely control the speed of the cooling fan or the start and stop of the air conditioner based on the internal temperature to achieve energy conservation and noise reduction.
Ensure output power: Prevent inverter derating operation due to excessively high temperatures and maximize power generation efficiency.
Extend equipment lifespan: Through effective temperature management, reduce the thermal stress on electronic components and extend the service life of inverters.
Iv. Automotive Manufacturing Industry
Application fields
Production equipment
Hydraulic/lubrication system for press/injection molding machine: Similar to general hydraulic and lubrication applications, it ensures the stable operation of equipment such as stamping and injection molding.
Painting workshop drying room, curing oven: Precisely control the baking temperature of the paint to ensure the quality of the paint surface.
Welding robot controller and welding torch: Monitor the temperature of the cooling water circuit to prevent overheating.
Application in automobiles themselves (as automotive components) :
Engine: Coolant temperature, oil temperature, intake air temperature sensors.
Transmission: Transmission oil temperature sensor.
The three-electricity system (for new energy vehicles) : motor winding temperature, motor controller temperature, battery pack temperature (overlapping with the new energy industry).
Function and Role
Ensuring process parameters: In processes such as coating and heat treatment, precise temperature control is the key to the consistency of product quality.
Equipment maintenance: Predict lubrication faults of key equipment such as the hydraulic station of the stamping line and robot reducers to reduce unplanned downtime.
Work safety: Monitor high-temperature equipment such as drying rooms and curing ovens to prevent fire risks.
