Product Description
WJK Marine Temperature Controller
Product Introduction:
The Marine Temperature Controller is an electronic control device specifically designed for shipboard heating, ventilation, air conditioning (HVAC), and industrial process temperature regulation. It receives input signals from temperature sensors (thermocouples, RTDs, or thermistors) and provides output signals (relay, 4-20mA, or voltage) to actuate control devices such as solenoid valves, electric heaters, fans, or pump motors. Built with marine-grade components, it withstands vibration, humidity, salt spray, and wide ambient temperature variations common in engine rooms, bridge panels, and cargo control rooms.
WJK series temperature controller can be used to control medium temperature of gas, liquid etc. by two position type in ship and other industrial instrument.
