Internal Side Mount Plastic Level Switch

A. Product Overview

The Internal Side Mount Plastic Level Switch Series is a miniature side-mounted float switch used for detecting liquid levels inside tanks and small process vessels. It is designed with nylon or polypropylene stem and float construction, making it suitable for water, mild chemicals, coolant, reservoirs and selected acid tank applications.

This level switch is mounted from the side of the tank using an M16 inverted male plug connection. The design is not dependent on tank size, making it suitable for compact equipment, small chambers, water chillers, water coolers and water bath systems.

The standard model comes with a 60 mm total length and 17 mm by 60 mm float size, with customizable options available based on application requirements. It supports operating temperatures from minus 40°C to 100°C and works under atmospheric pressure conditions. The standard switching capacity is 30VA, with voltage options up to 230V AC and 6V to 32V DC.

B. Working Principle

The Internal Side Mount Plastic Level Switch works on magnetic float and reed switch technology. A float moves up and down with the liquid level inside the tank. As the liquid level rises or falls, the float changes position around the stem.

Inside the stem, a reed switch is fitted. The float contains a magnet, and when the float reaches the switching position, the magnet activates the reed switch. This creates an electrical signal for level indication, pump control, alarm control or automation system input.

The switch can be configured for SPST NO or NC operation. This means it can be used either to close the circuit or open the circuit when the liquid reaches the desired level. The switching action is repeatable and reliable, making it useful for automatic liquid level monitoring in compact tanks and equipment.

C. Why It Is Used

The Internal Side Mount Plastic Level Switch is used to monitor and control liquid levels in tanks where a compact, cost-effective and chemically compatible level switch is required.

It helps prevent tank overflow, dry running of pumps, low level conditions and process interruptions. Since it is side mounted, it is useful when top mounting is not possible or when the tank design requires horizontal level detection.

It is preferred in applications where plastic wetted parts are suitable, especially for water, mild chemicals, reservoirs, chillers and equipment tanks. The miniature size makes it suitable for OEM machines, compact panels, small tanks and equipment where space is limited.

D. Suitable Buyers

This product is suitable for OEM machine manufacturers, water chiller manufacturers, water cooler manufacturers, process equipment manufacturers, automation panel builders, water treatment companies, chemical tank users, laboratory equipment manufacturers, maintenance departments and industrial buyers looking for compact plastic liquid level switches.

It is also suitable for industries using small storage tanks, chambers, reservoirs, cooling systems, acid tanks, water bath systems and utility equipment requiring simple on and off liquid level detection.

FAQ

1. What is an Internal Side Mount Plastic Level Switch?

An Internal Side Mount Plastic Level Switch is a compact float-operated level switch installed from the side of a tank to detect liquid level. It is commonly used for point level detection in small tanks, reservoirs, water chillers, water coolers and process chambers.

2. What is the material of RDCL-HFS-PP level switch?

The RDCL-HFS-PP level switch is made from nylon or polypropylene material for both stem and float. This makes it suitable for water, mild chemicals and selected process liquids where plastic construction is preferred.

3. What is the mounting connection of this level switch?

This level switch comes with an M16 inverted male plug process connection. It is designed for side mounting inside the tank.

4. What is the temperature range of this level switch?

The operating temperature range is minus 40°C to 100°C, making it suitable for many water, cooling and light chemical applications.

5. What is the switching type of this product?

The standard switching type is SPST NO or NC. The switch can be configured as normally open or normally closed based on the application requirement.

6. Where can this plastic side mount level switch be used?

It can be used in chambers, water reservoirs, water chillers, water coolers, acid tanks, water bath systems, small storage tanks and compact process equipment.

7. Is the length customizable?

Yes, the standard total length is 60 mm, but customized versions can be made depending on the tank design and application requirement.

8. What is the switching voltage range?

The switch supports up to 230V AC and 6V to 32V DC, depending on the electrical requirement and selected version.

9. What is the standard switching power?

The standard switching power is 30VA. Higher ratings can be provided depending on the application and model selection.

10. Why choose a plastic level switch instead of stainless steel?

A plastic level switch is preferred where the application requires corrosion resistance, lightweight construction and compatibility with water or selected chemicals. It is also a cost-effective option for compact tanks and OEM equipment.

11. Can this switch be used for pump protection?

Yes, it can be used for low level detection to help prevent dry running of pumps, and it can also be used for high level detection to avoid overflow.

12. Is this suitable for industrial automation panels?

Yes, the reed switch output can be connected to controllers, relays, alarms, indicators and automation panels for liquid level monitoring and control.
