Factory direct sales LCD / LED Digital display hydraulic pressure transmitter for the water treatment
Working Principle
The diffused silicon pressure transmitter is a common type of intelligent transmitter. It uses a diffused silicon pressure sensor as the sensing element, combined with high-precision electronic components and advanced signal processing technology to convert pressure signals into standard electrical signals for output. It features a simple structure, small size, light weight, stable performance, and ease of installation and use. It is widely used in industries such as petroleum, chemical, steel, electric power, light industry, and environmental protection, and can be used to measure physical quantities such as pressure, differential pressure, liquid level, and flow.

application scenarios
1. Smart Water Management and Water Supply Networks
Network End Monitoring: Due to the compact size of the 2088 housing, it is very easy to install in narrow pipe shafts or residential water meter boxes. Its smart features support remote pressure data reading, helping water utilities monitor network leakage, pipe burst warnings, and water pressure balance in real time.
Secondary Water Pump Rooms: Used for feedback control in constant pressure water supply systems. The fast response and digital communication capabilities of the smart transmitter can perfectly cooperate with variable frequency drives to achieve precise pump speed adjustments, resulting in significant energy savings.
Fire Water Tanks/Pools Liquid Level: The liquid level height is calculated by measuring static water pressure. The intelligent diagnostic function can prevent false alarms caused by sensor failures.
2. HVAC Systems
Air and Water Pressure Monitoring: Widely used for monitoring static air pressure in central air conditioning ducts and pressure in chilled/hot water pipelines. Its compact design makes it easy to embed within complex air handling units.
Building Automation System (BAS): Supports protocols such as Modbus and can be directly connected to the building control network without additional signal conversion modules, simplifying system integration and enabling centralized monitoring of pressure and energy management across floors.
3. Petrochemical and Process Control
Small and Medium Storage Tanks and Pipelines: Suitable for pressure monitoring of non-strongly corrosive oils and chemical raw materials. The temperature compensation function of the smart transmitter ensures measurement accuracy in outdoor environments with large temperature differences.
Pump and Compressor Protection: Monitors pump inlet vacuum and outlet pressure to prevent cavitation or overload. Its self-diagnosis function can issue early warnings in case of sensor anomalies to avoid equipment damage.
Water/Gas Injection Processes: In oilfield water injection systems, it is used to monitor injection pressure. The remote range adjustment function facilitates unified calibration for pressure ranges of different wells.
4. Mechanical Manufacturing and Hydraulic/Pneumatic Systems
Hydraulic Station Pressure Monitoring: Installed near hydraulic pump stations or actuators to monitor system pressure. Its vibration-resistant design and robust stainless steel housing adapt to harsh mechanical site environments.
Pneumatic System Testing: Used for pressure detection at air compressor outlets, air tanks, and pneumatic pipelines, working with PLCs to realize automated control logic.
5. Energy and Environmental Monitoring
Boiler Flue Gas Pressure: Monitors furnace negative pressure or flue pressure to ensure combustion efficiency and safe exhaust.
Gas Transmission Networks: Pressure monitoring for gases such as natural gas and coal gas; the smart remote transmission function meets the monitoring needs of unmanned station houses.
6. Food and Pharmaceutical Industry (Hygienic Applications)
Clean Pipeline Monitoring: Some 2088 series offer hygienic flanged or clamp interfaces and are made of materials compliant with food hygiene standards. They are used to monitor pressure in fermentation tanks, ingredient tanks, and transfer pipelines. Their dead-zone-free design makes them easy to clean and disinfect (CIP/SIP). ...
