FTS20 Float Level Gauge Spare Parts Selection Guide
FTS20 float level gauge is a compact instrument for liquid point level detection, using a float-driven microswitch to provide double-throw contact output. Its cylindrical float can be directly installed through a G1 thread, making it suitable for various industrial scenarios. This article summarizes the order numbers, technical parameters, and applicable media of FTS20 series spare parts to facilitate quick selection by engineering technicians and procurement personnel.
Standard Spare Parts (Microswitch Output)
The standard FTS20 float level gauge has a built-in microswitch double-throw contact, with a contact capacity of 250VAC/150VDC, suitable for liquid level limit detection in non-explosion-proof applications. Depending on cable material and length, it is available in multiple order numbers to suit different media and environments.
Cable Materials and Applicable Media
- CSM cable: Resistant to acid and alkali corrosion, suitable for chemical liquids.
- PUR cable: Resistant to fuel and oils, suitable for oil and fuel environments.
- PVC cable: Suitable for water and wastewater treatment.
Standard Order Numbers and Parameters
| Order Number | Cable Material | Cable Length | Applicable Media |
|---|---|---|---|
| 71035522 | CSM | 20m | Acids, alkalis |
| 71035521 | PUR | 20m | Fuel, oils |
| 71035520 | PVC | 20m | Water, wastewater |
| 52010124 | CSM | 5m | Acids, alkalis |
| 52010123 | PUR | 5m | Fuel, oils |
| 52010122 | PVC | 5m | Water, wastewater |
NAMUR Explosion-Proof Spare Parts
The NAMUR explosion-proof FTS20 float level gauge complies with the EN60947-5-6 (NAMUR) standard, requires an isolation amplifier for operation, and has ATEX II 2G EEx ia IIB T5 explosion-proof certification, suitable for flammable and explosive hazardous areas. It also offers multiple cable material and length options.
NAMUR Explosion-Proof Order Numbers and Parameters
| Order Number | Cable Material | Cable Length | Applicable Media |
|---|---|---|---|
| 71035518 | CSM | 20m | Acids, alkalis |
| 71035516 | PVC | 20m | Water, wastewater |
| 52010121 | CSM | 5m | Acids, alkalis |
| 52010120 | PUR | 5m | Fuel, oils |
| 52010119 | PVC | 5m | Water, wastewater |
Selection Notes
- Confirm the application environment: Select the cable material based on media corrosiveness (CSM for acid and alkali resistance, PUR for oil resistance, PVC for water).
- Determine explosion-proof requirements: If explosion protection is required, choose the NAMUR type and ensure the system is equipped with an isolation amplifier.
- Cable length: Standard lengths are 5m and 20m; other lengths can be customized.
- Installation method: The float is cylindrical and can be directly installed through a G1 thread, ensuring sealing.
The above spare parts are all suitable for liquid point level detection. The float material is PP (polypropylene), which has good chemical resistance. For more technical information, please contact us.
