Product Description P/N: 7ML12011EF00
Description
The Siemens 7ML1201-1EF00 is a non-contact ultrasonic level transmitter from the Siemens The Probe series, designed for continuous level measurement of liquids in open or closed tanks and vessels. It provides a measuring range of 0.25 to 5 meters and uses ultrasonic technology to determine the distance between the sensor and the liquid surface. With a 2-inch NPT process connection, 24 V DC power supply, and 4–20 mA output, this transmitter supports level monitoring in industrial process applications.

Information About 7ML1201-1EF00
The Siemens 7ML1201-1EF00 is an integrated ultrasonic level transmitter designed for continuous, non-contact measurement of liquids. It emits ultrasonic pulses and calculates the liquid level from the time required for the reflected echo to return to the sensor. Siemens Sonic Intelligence echo-processing technology helps distinguish the actual liquid-surface echo from false echoes caused by electrical noise, acoustic interference, or moving equipment. The transmitter includes temperature compensation and a two-wire, 24 V DC configuration with a 4–20 mA analog output, allowing integration with compatible process controllers and monitoring systems.
Key Features:
- Non-Contact Level Measurement: Measures liquid levels using ultrasonic pulses without direct contact with the process material.
- 5 m Measuring Range: Supports continuous level measurement over a range of up to 5 meters for compatible applications.
- 4–20 mA Analog Output: Transmits level measurement signals to compatible PLCs, controllers, and process monitoring systems.
- 24 V DC Power Supply: Uses a two-wire DC configuration for industrial instrumentation applications.
- Sonic Intelligence Processing: Helps distinguish valid liquid-surface echoes from false echoes caused by noise and moving equipment.
- Integrated Temperature Compensation: Compensates for temperature-related changes affecting ultrasonic measurement.
- 2-Inch NPT Process Connection: Supports installation in compatible tank openings and process fittings.
- IP65 Protection: Provides protection against dust ingress and water jets when correctly installed.
The Siemens 7ML1201-1EF00 provides continuous ultrasonic level monitoring for liquid storage, process vessels, and industrial fluid-handling applications.
