NAKAKITA Temperature Controller (0-150°C)

The NAKAKITA Temperature Controller (0-150°C) is a high-quality, mechanical/pneumatic instrument from the renowned Japanese manufacturer NAKAKITA SEISAKUSHO, designed to provide accurate and reliable temperature control in the most demanding marine and industrial environments.

Precise Pneumatic Control
This controller is a fully self-contained unit that combines temperature sensing, indication, and control. It utilizes a temperature sensing bulb (typically with a 5-meter capillary cable) to measure the process temperature. The measured value is clearly displayed on an integrated, easy-to-read scale calibrated for 0 to 150°C.

Standardized Output Signal
The controller translates the temperature measurement into a proportional pneumatic output signal. The standard output is 0.2 – 1.0 KGF/CM² (approximately 20–100 kPa or 0.2–1.0 bar), which is the industry-standard signal for pneumatic control systems. This signal is used to directly position a pneumatic control valve, damper, or other final control element, providing simple and effective temperature regulation without the need for electrical power.

Robust and Reliable Design
True to NAKAKITA’s reputation, this instrument is engineered for longevity and reliability. Key features include:

• Mechanical Durability: Designed to withstand the vibration and harsh conditions found in marine engine rooms and industrial plants .

• Pneumatic Operation: Intrinsically safe and unaffected by electrical interference, making it ideal for a wide range of environments.

• Clear Indication: The large, local dial allows for immediate visual confirmation of the process temperature, independent of any remote monitoring system .

Typical Applications
This type of controller is commonly used in various marine and industrial systems, including:

• Fuel Oil Systems: Controlling the temperature of fuel oil to ensure proper viscosity for combustion.

• Lubricating Oil Systems: Maintaining optimal lube oil temperature for engines and machinery.

• Cooling Water Systems: Regulating the temperature of jacket water or central cooling systems.

• HVAC Systems: Controlling heating or cooling coils in ventilation systems.

While specific model numbers like TBT732, NSTM 732, or NS-TM-732 appear on various units, the core functionality of a 0-150°C indicating pneumatic controller remains consistent, offering a proven and reliable solution for critical temperature control applications .
