🖹 Description
Fixed-range pressure indicating controllers measure and adjust gauge pressures, pneumatic signals at 0-100°C by means of spiral or bellows element.
Output: 0,2-1 bar
Capillary Height : 88mm
This is a temperature controller with capillary sensor — very similar in concept to the previous Yamatake NFT2, but in a slightly different format/range.
This device is an industrial temperature controller with capillary sensor, designed for reliable temperature regulation in mechanical or pneumatic control systems. It combines measurement and control in a single unit, making it ideal for applications where simplicity and robustness are required.
What It Is
The KGTA12 is a mechanical temperature controller that measures temperature via a remote probe and compares it to a setpoint. Based on this comparison, it controls a process either by switching an electrical contact (ON/OFF) or by generating a pneumatic signal, depending on the configuration.
What It Does
This controller performs three essential functions:
- Measures temperature through a capillary probe
- Compares the measured value with a desired setpoint
- Controls the process automatically
It is commonly used in systems where stable temperature control is critical.
Design and Components
The device features a classic industrial design:
- Front dial (0–100°C): Displays current temperature and allows setpoint adjustment
- Capillary tube and probe: Enables remote temperature sensing
- Controller housing: Contains the internal mechanical control system
- Pressure gauge (bottom): Indicates output signal (in pneumatic versions)
How It Works
The operation is based on thermal expansion:
- Temperature changes at the probe
- Fluid inside the capillary expands or contracts
- This movement is transmitted to the internal mechanism
- The controller responds by:
- Activating a switch (ON/OFF control), or
- Sending a pneumatic control signal
Typical Applications
This type of controller is widely used in:
- Hot water systems
- Boilers and heating systems
- Heat exchangers
- Industrial temperature control loops
Key Features
- No electricity required (in pneumatic versions)
- Reliable and robust mechanical operation
- Suitable for harsh or hazardous environments
- Remote sensing capability via capillary

In Simple Terms
Think of the KGTA12 as a mechanical thermostat combined with an industrial controller, capable of automatically regulating temperature.
Role in a Control System
Process temperature → Controller → Signal (air or switch) → Valve / heater
Big Picture
This device belongs to the control layer of industrial automation systems, where decisions are made based on measured values.
Final Overview
At this point, you’ve seen the complete industrial instrumentation chain:
- Transmitters → continuous measurement
- Switches → ON/OFF protection
- Controllers → decision-making (this device)
- Converters/regulators → signal handling
- Positioners → precision control
- Valves/actuators → final action
