This is a pneumatic temperature controller with capillary sensor.
The pneumatic temperature controller with capillary sensor model NFT2 by Yamatake (Azbil) is a reliable and fully mechanical process control device designed for accurate temperature regulation in industrial applications. This controller operates without electricity, using pneumatic principles and a capillary sensing system to maintain stable temperature conditions.
What It Is
The NFT2 is a temperature indicating pneumatic controller that measures process temperature, compares it to a desired setpoint, and outputs a proportional pneumatic signal (typically 3–15 psi) to control a valve or actuator. It combines sensing, control, and indication in a single compact unit.
What It Does
This device performs three essential control functions:
- Measures temperature via a remote capillary sensor
- Compares the measured value to the setpoint
- Generates a pneumatic output signal to regulate temperature
This makes it a complete analog controller, similar in concept to modern PID controllers but operating entirely with air.
Design and Components
The controller features a robust industrial design:
- Dial (0–150°C): Displays current temperature and allows setpoint adjustment
- Capillary tube and probe: Remote temperature sensing element
- Controller housing: Contains the pneumatic control mechanism
The capillary sensor is filled with a fluid that expands or contracts depending on temperature changes.
How It Works
The operating principle is simple and effective:
- Temperature changes at the sensing probe
- The fluid inside the capillary expands or contracts
- This mechanical change is transmitted to the controller
- The controller generates a pneumatic output signal (3–15 psi)
- The signal drives a control valve or actuator
Why the Capillary Sensor Is Important
- Enables remote temperature measurement
- Allows installation of the sensor far from the controller
- Eliminates the need for electrical wiring
Typical Applications
The NFT2 pneumatic temperature controller is widely used in:
- Boilers and steam systems
- Industrial ovens and furnaces
- Heat exchangers
- Heating and thermal process systems

Advantages
- No electrical power required
- High reliability in harsh or hazardous environments
- Simple and durable construction
- Continuous and stable temperature control
In Simple Terms
Think of the NFT2 as a “mechanical thermostat combined with a controller,” using air pressure instead of electricity to regulate temperature.
Role in a Control Loop
Process temperature → Capillary sensor → Controller → Pneumatic signal → Control valve → Temperature regulation
Big Picture
In a complete industrial control system:
- Sensors measure process conditions
- Controllers (like this device) make decisions
- Valves and actuators execute control actions
Overall, the Yamatake NFT2 is a key component in traditional pneumatic control systems, offering dependable and precise temperature regulation without the need for electronic systems.
