Overview
The Siemens 1P7ML5004-1AA10-1A SITRANS LU 01 is an ultrasonic long-range level monitoring system designed for single-channel measurement of liquids and bulk solids. This AC-powered evaluation unit operates up to 60 m (200 ft) measuring range and is Smartlinx-ready for seamless integration into modern control systems. Built for reliability with minimal maintenance requirements, the SITRANS LU 01 handles diverse industrial level measurement applications.
Key Features
- Single-point ultrasonic level measurement for liquids and solids
- Measuring range up to 60 m (200 ft) with non-contact operation
- Smartlinx-ready for optional communication module integration
- Automatic air temperature compensation for accuracy
- Large illuminated LCD display for clear reading visibility
- Wall-mount enclosure with CE, CSA NRTL/C, and FM certifications
- Programmable parameters accessible via intuitive menu interface
Technical Specifications
The monitor features selectable AC input voltage (100/115/200/230 V) via voltage selector switch, eliminating the need for external transformers in most facilities. Peripheral communication terminals (27 and 28) support data transmission to SCADA and remote monitoring systems. The unit performs level, space, or distance calculations with custom graphic symbol display and scroll-accessible programming. Temperature sensing via optional TS-3 temperature sensor ensures accuracy across varying process conditions.
Typical Applications
- Water treatment and wastewater level monitoring
- Chemical storage tank management
- Bulk solids inventory monitoring (silos, hoppers)
- Industrial process control and automation
- Open channel flow measurement
- Vessel and wet well monitoring
Compatibility & Replacements
The SITRANS LU 01 integrates with Siemens SITRANS Probe LU ultrasonic transmitters and radar-based level transmitters via standard mA signal interfaces. The Smartlinx-ready design supports future communication module expansion without hardware replacement. This unit is compatible with SCADA systems, Siemens automation controllers, and legacy industrial monitoring networks using standard peripheral communication protocols. The fixed programming lock provides backup security; consult Siemens technical support for specific integration guidance with proprietary systems.
