Side Mounted Heavy Duty High Temperature Level Switch

A. Product Overview

The Side Mounted Heavy Duty High Temperature Level Switch is used for point level detection in industrial tanks where liquids are stored or processed at high temperatures. It is mounted from the side of the tank and operates through a float mechanism that moves with the liquid level.

This level switch is suitable for applications where normal plastic or light duty level switches are not suitable due to high temperature, industrial environment, chemical exposure or heavy duty operation. The float and assembly are available in SS304 or SS316, making it suitable for water, oil, chemicals, hot liquids and process media.

The product includes a cast aluminium flame proof enclosure, ceramic terminal block for wire connection, and square flange mounting, which makes it suitable for demanding industrial installations.

B. Working Principle

The switch works on a simple float operated principle. A stainless steel float is fitted inside the tank from the side mounting point. As the liquid level rises or falls, the float moves along with the liquid level.

This float movement activates the internal switching mechanism and changes the contact position. The switch can provide Common, Normally Open and Normally Closed contact output. This signal can be used to control a pump, alarm, indicator, control panel or automation system.

When the liquid reaches the set level, the switch changes its output state. This helps detect high level, low level or specific point level conditions inside the tank.

C. Why It Is Used

This level switch is used where reliable liquid level control is required in high temperature and heavy duty industrial applications. It helps prevent tank overflow, dry running of pumps, process interruption and unsafe liquid level conditions.

It is especially useful where the application requires a strong metallic float switch instead of a compact plastic or miniature level switch. Because of its heavy duty construction and high temperature suitability, it can be used in applications such as boilers, oil tanks, chemical tanks, hot water tanks, hydraulic oil tanks, lubrication systems, process vessels and industrial storage tanks.

Key reasons for using this product:

Reliable level detection in high temperature liquid applications
Suitable for heavy duty industrial tanks and vessels
