Marine UQK type Alarm Level Switch
A Marine UQK Level Switch is an electromechanical device used on ships to detect and monitor the level of liquids in various tanks (e.g., fuel oil, lubricating oil, fresh water, sea water, bilge wells). Its primary function is to provide high-level and low-level alarms to prevent overflows or run-dry conditions that could damage machinery or cause environmental hazards.
Overview
Technical Parameters
Operating Voltage: Typically ranges from 220V AC to 380V AC, depending on the model.
Current Rating: Generally, the current rating is around 5A.
Contact Form: SPDT (Single Pole Double Throw) or DPDT (Double Pole Double Throw) configurations.
Switching Capacity: Can handle loads up to 500W (resistive load).
Operating Temperature: Usually between -40°C to 60°C.
Material
Float: Stainless steel or plastic, resistant to corrosion and seawater.
Body: Often made from robust materials like stainless steel or marine-grade plastic.
Mounting: Can be flange-mounted or threaded for secure installation.
Ingress Protection: Typically IP65 or higher, ensuring protection against dust and water ingress.
