Product Description
The controller receives temperature information from the fuel-oil heating system and generates a proportional pneumatic control signal. This signal modulates the heater’s steam or thermal-medium control valve, helping maintain the programmed fuel-oil temperature supplied to the main engine.
Before replacement, confirm the complete model, temperature range, sensing-element arrangement, control direction and pneumatic connections. The specifications above apply to the photographed 0–150°C NS‑TBT‑734 configuration.
