Marine Pressure Type Temperature Controller
The Marine Pressure Type Temperature Controller is a heavy-duty, high-precision instrument designed for the rigorous demands of maritime and industrial environments. Utilizing a liquid-expansion pressure principle via a sensing bulb and capillary, it provides reliable switching control for gaseous or liquid media. Available in a waterproof cast aluminum housing for marine applications or a phenolic resin housing for general use, this controller is engineered to operate accurately even under significant vibration and tilting conditions. With a broad adjustable range from -60 to 170 °C and high contact capacity, it is the standard choice for refrigeration, steam systems, and engine room temperature management.
Description
Overview of Marine Pressure Type Temperature Controller
The Marine Pressure Type Temperature Controller is a mechanical sensing device used to maintain temperature setpoints in industrial and shipboard systems.
What is it? It is a pressure-actuated switch equipped with a remote sensing bulb connected to the main controller body via a flexible capillary tube. It is designed for media that are non-corrosive to copper alloys, such as steam, air, and various liquids. The controller allows for precise adjustment of both the setpoint (lower switching value) and the differential (deadband).
Principles of Operation: The controller operates on the liquid expansion/pressure principle. The sensing bulb and capillary are filled with a temperature-sensitive fluid.
As the temperature at the bulb changes, the internal pressure varies, acting upon a bellows or diaphragm within the controller. This mechanical movement trips a high-capacity SPDT micro-switch at the designated setpoint. Main Application Field: The waterproof cast aluminum version is specifically designed for marine vessels, offshore platforms, and coastal installations.
It is widely used in cold storage refrigeration units, HVAC systems, steam pipelines, and industrial furnaces. Key Characteristics: This controller is distinguished by its excellent vibration resistance and ability to function normally even when tilted up to 22.5°. It features an adjustable differential range and a high-load contact capacity (up to 3A at 380VAC), making it suitable for direct control of motors and valves.
Features of Marine Pressure Type Temperature Controller
Specialized Marine Construction: Available in a rugged cast aluminum housing with IP44 protection, designed to withstand salt spray, moisture, and extreme sea conditions.
Remote Sensing Capabilities: Equipped with capillaries ranging from 1m to 12m, allowing the controller to be mounted on an instrument panel while the bulb is placed deep inside a tank or cold room.
Vibration and Tilt Resistance: Specifically calibrated for shipboard use, ensuring stable switching under mechanical vibration and the rolling/pitching of a vessel.
Wide Temperature Range: Covers a vast operational spectrum from -60 °C (for specialized freezing) up to 170 °C (for steam and heating processes).
Adjustable Differential: Features an adjustable deadband, allowing users to fine-tune the gap between the "start" and "stop" temperatures to prevent short-cycling of equipment.
High Reliability SPDT Switch: Includes a Single Pole Double Throw (SPDT) micro-switch for flexible control logic (Normally Open or Normally Closed).
Applications of Marine Pressure Type Temperature Controller
Marine Refrigeration & Cold Storage: Maintaining precise temperatures in shipboard food storage and refrigerated cargo holds.
Steam System Control: Monitoring and regulating steam temperatures in heating systems and industrial laundries.
Engine Room Monitoring: Controlling cooling water or lubrication oil temperatures in marine diesel engines.
Industrial Furnaces: Providing over-temperature protection or regulation in heating and drying equipment.
HVAC Systems: Temperature regulation for air handling units in harsh or outdoor environments.
Price of Marine Pressure Type Temperature Controller
The price of the Marine Pressure Type Temperature Controller varies based on the housing material (Cast Aluminum vs. Phenolic Resin), the required temperature range, and the length of the capillary (up to 12m).
