Tecfluid LT-R153 – Magnetic Level Transmitter with Switch

Overview

High-Precision Industrial Level Measurement

The Tecfluid LT-R153 – Magnetic Level Transmitter with Switch is engineered for accurate, reliable liquid level control in industrial applications where safety, durability, and process stability are essential. Utilizing magnetic float coupling, the LT-R153 delivers continuous level detection with zero leakage risk, because the sensor and electronics remain isolated from the fluid.

This design principle ensures long-term stability and resistance to harsh process environments, including corrosive, high-pressure, and flammable liquid systems. It’s ideal for use in tank farms, chemical processing units, boiler systems, and oil & gas installations.

Magnetic Float Technology & Operation

The core of the LT-R153’s functionality lies in magnetic float technology. A magnetic float moves up and down the outside of a sealed chamber as liquid levels change. Inside the chamber, magnetic coupling transfers this movement to the transmitter and switch mechanism without any direct contact with the process fluid — eliminating the possibility of leakage or sensor contamination.

This non-intrusive measurement technique offers:

• Leak-free operation

• Maintenance-free performance

• High reliability in extreme conditions

  All while providing accurate and repeatable level data to control systems.

Key Features

Continuous Level Monitoring

The LT-R153 provides a continuous and real-time measurement of liquid levels based on magnetic float movement, making it highly suitable for process automation systems that require dependable input signals for control and safety.

Integrated Switch Outputs

Equipped with limit switch outputs, this transmitter signals when liquid levels reach preset thresholds — commonly for low level (LSL) and high level (LSH) alarms. These outputs are configurable for automation systems, safety interlocks, pump controls, and alarm triggers.

Rugged Industrial Construction

Built for demanding industrial environments, the LT-R153 supports connections such as DN50 PN40 flanges, suitable for pressurized vessel installations. The robust mechanical design ensures stable operation under vibration, temperature variation, and harsh conditions.

Explosion-Protected Options

Explosion protection versions (e.g., Ex d II C T4) are available for classified hazardous areas, improving safety for volatile fluid applications.

Flexible Integration

The transmitter can be integrated into PLC, DCS, SCADA, or standalone control systems through industry-standard analog or digital interfaces (switch contacts, 4-20 mA, HART, etc.), depending on configuration.

Technical Specifications

Note: Specific materials and options (e.g., PVDF, 316L, PTFE floats) depend on fluid compatibility and system requirements.

Industrial Applications

The Tecfluid LT-R153 Magnetic Level Transmitter with Switch is ideal for:

• Tank and vessel liquid level monitoring

• Chemical processing units

• Petrochemical and refinery level control

• Boiler feedwater and steam systems

• Wastewater treatment plants

• Marine fuel and ballast systems

• Oil & gas production & storage terminals

• Any industrial system requiring reliable high/low level control

Its versatile performance and rugged design make it a preferred choice for automation engineers and safety professionals.

FAQ

How does magnetic level measurement differ from capacitive or radar methods?

Magnetic level transmitters rely on magnetic coupling and a float, which eliminates direct contact between electronics and process fluid — offering superior leak resistance and simpler maintenance.

Can the LT-R153 handle corrosive liquids?

Yes — with appropriate material selection (e.g., 316L, PVDF, PTFE), it can measure levels in corrosive and hazardous fluids.

Is this suitable for high-pressure tanks?

Yes — with DN50 PN40 flange connections, the transmitter is designed for pressurized systems.

Can it connect to automation systems?

Yes — switch contacts and optional analog/digital outputs allow integration into PLC, SCADA, and control loops.

Does it support explosion-proof installation?

Explosion-protected variants are available (e.g., Ex d II C T4) for hazardous locations.
