SR-80 Rotary Paddle Level Switch Order for an Italy Customer
An Italy customer recently contacted us for the SR-80 rotary paddle level switch, a compact and reliable material level detection device used in silos, hoppers, bucket elevators, chain conveyors and other bulk material handling systems.
At the beginning of the inquiry, the customer requested only 3 units for evaluation. After confirming the specification, thread connection and voltage options, the order quantity was increased. The final shipment included 6 pieces of SR-80 level switches: 4 pcs in 230VAC and 2 pcs in 24VDC.
This project is a good example of how small replacement part inquiries can develop into repeatable orders when the specification is clear and the customer receives a suitable solution.
Customer Requirement
The customer needed a standard SR-80 type rotary paddle level switch, but with a customized thread connection.
The main requirements included:
- Model: SR-80 rotary paddle type level switch
- Connection method: 1″ PF thread
- Insertion length: 85 mm
- Voltage: 230VAC × 4 pcs; 24VDC × 2 pcs
- Application: Material level detection for bulk handling equipment
- Quantity: 6 pcs
- Destination: Italy
- Packing: one carton, 350 × 300 × 260 mm
- Gross weight: 7 kg
The SR-80 level switch is commonly used to detect full or empty material levels in storage silos, feeding systems, bucket elevators and conveyor equipment. When the material reaches the paddle, the rotation resistance changes and the switch sends a signal to the control system.
For customers working with grain, feed, seed, powder or other bulk materials, this type of level switch helps improve process control and reduce overflow, blockage or empty-running risks.
Customized 1” PF Thread Connection
The standard drawing of the SR-80 level switch shows the original thread design. For this Italian order, the customer required a 1″ PF thread connection with an 85 mm insertion length.
This small modification is important because the thread must match the customer’s existing installation position. A correct connection size helps the customer install the level switch faster without changing the silo wall, mounting seat or existing equipment structure.
For replacement projects, we always suggest checking the following details before production:
- Existing thread size or mounting hole size
- Paddle length and blade type
- Voltage requirement
- Wiring method
- Working material and temperature
- Installation position on silo, hopper or conveyor equipment
This helps reduce mistakes and ensures that the level switch can be installed smoothly after arrival.
230VAC and 24VDC Versions in the Same Order
In this project, the final order included two voltage types:
- SR-80 with 1″ PF thread, 230VAC — 4 pcs
- SR-80 with 1″ PF thread, 24VDC — 2 pcs
Different equipment lines may use different control systems, so voltage confirmation is a key step before production. Some customers use 230VAC for industrial control panels, while others require 24VDC for low-voltage control circuits.
By confirming this detail before shipment, we helped the customer receive the correct models for different installation points.
Packing and Shipment Details
After production and inspection, the SR-80 rotary paddle level switches were packed together in one carton.
Packing details:
- Carton size: 350 × 300 × 260 mm
- Gross weight: 7 kg
- Packing method: carton packing for small quantity shipment
- Product protection: each level switch was arranged carefully to protect the housing, thread, cable gland and paddle blade during transportation
For small electrical and mechanical components, secure packing is important because the paddle blade and cable outlet should not be bent or damaged during international delivery.

From Small Trial Order to Increased Quantity
This Italy project started with a small quantity inquiry. The customer first requested 3 units to confirm the product and application. After technical communication, the order quantity increased, and the final production was arranged according to the confirmed specification.
For many industrial spare parts, customers do not always place large orders at the beginning. A small trial order helps them check product quality, installation suitability and communication efficiency.
For us, even a small order is handled seriously because it may become the first step for future cooperation.
Project Summary
This SR-80 rotary paddle level switch project shows our ability to support customers with standard products and small customization requirements. The Italian customer needed a reliable level switch with a specific thread connection, and we manufactured the units according to the confirmed 1” PF thread requirement.
With 4 pcs in 230VAC and 2 pcs in 24VDC included, the shipment was prepared for different control requirements in the customer’s equipment.
