Relative pressure transmitter LFT2000

ceramicMEMS4-20 mA

Product overview
The LFT2000 pressure transmitter measures gas or liquid pressure in industrial test systems such as fire protection, water treatment, water supply, air compressors, pneumatic equipment and factory automation. It uses a ceramic sensitive diaphragm with high overload capacity and integrates ASIC and MEMS technologies with digital compensation. Compact and cost-effective, the sensor is suited to varied and demanding environments.

Key features

• Ceramic sensitive diaphragm offering high overload resistance.
• Good corrosion and wear resistance for compatibility with common media.
• ASIC + MEMS design with digital compensation for stable output.
• Compact size with multiple thread and electrical connection options.
• Available output types and protection classes to fit application needs.
