SITRANS-AS100-ET

Product Description

It is part of the SITRANS Probe LU series, offering reliable non-contact level detection with a measuring range of up to 6 meters (19.7 ft) for liquids and 2.5 meters (8.2 ft) for solids. The sensor operates at a frequency of 40 kHz and is engineered for use in open channels, weirs, and tanks, providing accurate level data even in dusty or humid environments. This sensor features a robust PVDF housing with IP68 protection, making it suitable for harsh industrial conditions. It is designed to be used with the SITRANS Probe LU transmitter, which provides power and signal processing. The AS100-ET is also compatible with the SITRANS LU10 and LU02 controllers, enabling multi-vessel monitoring. The sensor's compact size (approximately 100 mm in length) and 2-inch NPT or G2 thread allow for easy installation in existing process connections. With a temperature range of -40°C to +80°C (-40°F to +176°F) and a pressure rating of 0.5 to 3 bar (7 to 43 psi), the AS100-ET is versatile for various applications, including water treatment, chemical storage, and food processing. Its low power consumption and 2-wire loop-powered design simplify wiring and reduce installation costs. The sensor is certified for hazardous areas (ATEX, FM, CSA) when used with appropriate barriers, ensuring safety in explosive environments. The Siemens SITRANS AS100-ET is a compact ultrasonic sensor designed for continuous level measurement of liquids and solids in industrial applications.

Technical Specifications

Version & Model Difference

The SITRANS AS100-ET is a specific sensor variant within the SITRANS Probe LU series. There are two main versions: the standard AS100 (7ML1100-1BA10) and the AS100-ET (7ML1100-1BA20). The -ET version is designed for extended temperature range and enhanced chemical resistance, making it suitable for more aggressive media. Additionally, the AS100-ET is available with different approvals (e.g., ATEX, FM) depending on the ordering code. The standard AS100 has a shorter cable length and lower temperature rating. Always verify the exact model number for your application requirements.
