2.5 Reinforced Cable Sealing

An intensive cable sealing structure helps protect the connection area and supports extended service life under mechanical loading conditions. Proper cable routing, installation, and strain relief remain important for reliable operation.

2.6 Transient Voltage Protection

A built-in transient voltage protection circuit helps protect the transmitter against electrical transients. Appropriate power supply design and system-level electrical protection are still recommended.

2.7 Durable Isolation Membrane

Laser-welded isolation membrane technology supports the durability of the sensing structure. Alternative sensor technologies may be available for selected applications involving viscous or acid-base media, subject to configuration and material compatibility.

2.8 Flexible Signal Outputs

The TS201 offers current and voltage output options for integration with compatible PLCs, data acquisition systems, indicators, and industrial control equipment.

Available outputs include:

• 4–20 mA

• 0–5 V

• 1–5 V

• 0–10 V

• Customized output options, subject to confirmation

2.9 Optional Temperature Measurement

A temperature measurement signal output is available as an option, allowing projects that require both level and temperature information to discuss an appropriate configuration with the supplier.

3. Technical Specifications

Note: Confirm the exact measurement range, output type, pressure connection, material configuration, and electrical requirements when ordering. The selected configuration determines the applicable specifications.

4. Typical Applications

The TS201 Submersible Level Transmitter is designed for liquid level monitoring in compatible industrial environments, including:

• Sewage treatment: Continuous level monitoring in compatible wastewater tanks and treatment facilities.

• Open tank level measurement: Monitoring liquid levels in open storage and process tanks.

• Industrial liquid storage: Level measurement for compatible non-corrosive liquids.

• Liquid processing systems: Integration with compatible process monitoring and control equipment.

• Acid and alkali tank applications: Potential use in selected aggressive liquid applications only when the sensing materials, seals, and optional sensor technology are confirmed as compatible.

For corrosive, viscous, or chemically aggressive media, verify the wetted material compatibility with the supplier before installation. The standard specification lists media compatible with 304 stainless steel and should not be assumed suitable for every acid, alkali, or wastewater composition.

5. Product Configuration and Selection Guide

To select the correct TS201 configuration, buyers should confirm the following parameters:

Measurement range: Select a range based on the maximum liquid depth and expected operating conditions.

Output signal: Choose 4–20 mA, 0–5 V, 1–5 V, 0–10 V, or a confirmed customized output according to the receiving instrument or control system.

Power supply: Confirm that the available supply is within 9–30 V DC.

Pressure connection: Select M20×1.5, M18×1.5, or M12×1, subject to the required configuration.

Measured medium: Provide the liquid composition and operating conditions to verify compatibility with the housing, isolation membrane, and sealing materials.

Temperature conditions: Confirm that the operating temperature and compensated temperature requirements fall within the specified limits.

Optional functions: Specify whether a temperature measurement output or alternative sensor technology is required.

Providing these details helps the supplier confirm a suitable configuration and reduce integration issues during installation.
