Utility & power generation
The differential pressure switch model DPD2T-H18 by Barksdale is a robust, heavy-duty industrial device designed for reliable monitoring and control of pressure differences in demanding environments. Built with a durable metal housing and engineered for high performance, this switch is ideal for critical applications where safety and system protection are essential.
What It Is
The DPD2T-H18 is an electro-mechanical differential pressure switch that measures the pressure difference between two points in a system. When the pressure differential reaches a predefined setpoint, the device activates electrical contacts, enabling automated control or safety actions.
What It Does
This switch continuously monitors pressure conditions and responds automatically when thresholds are exceeded. It can:
- Trigger alarms
- Send signals to PLC or control systems
- Shut down equipment to prevent damage
Unlike simple indicators, it actively participates in system control and safety.
What Makes It Different
Compared to lighter-duty switches (such as standard HVAC models), the Barksdale DPD2T-H18 offers:
- Rugged metal construction for harsh industrial environments
- Higher pressure handling capability
- Reliable operation in demanding conditions (oil, gas, heavy industry)
- Dual output switching (DPDT), allowing greater control flexibility
Design and Components
The device features a solid industrial design:
- Top housing: Contains electrical contacts and adjustment mechanism
- Bottom section: Houses the pressure sensing element (diaphragm or piston)
- Connection ports: Allow installation across high and low pressure points
This design ensures durability, accuracy, and long service life.
How It Works
The operation is simple and effective:
- Pressure is applied to both sides of the sensing element
- As the pressure difference increases, the internal mechanism moves
- When the setpoint is reached, the switch toggles (ON/OFF)
- An electrical signal is sent to the system
Typical Applications
The DPD2T-H18 is widely used in:
- Industrial filtration systems
- Hydraulic systems
- Compressor monitoring
- Oil & gas and heavy industry
- Safety shutdown and interlock systems
Advantages
- High durability and reliability
- Automatic system protection
- Suitable for harsh environments
- Flexible control with dual switching outputs
In Simple Terms
Think of this device as a heavy-duty pressure difference alarm and control switch, built for tough industrial conditions.
Role in a System
- Differential indicator → visual monitoring
- Basic pressure switch (e.g., HVAC) → standard automation
- Barksdale DPD2T-H18 → advanced industrial control and safety
Overall, the Barksdale DPD2T-H18 differential pressure switch is an essential component for maintaining safety, efficiency, and reliability in industrial systems where pressure monitoring is critical.
