Piezoresistive pressure transmitter LFT2030

4-20 mA0-10 Vvoltage output

Product overview
The LFT2030 high-temperature pressure transmitter integrates a high-performance sensing element and a dedicated ASIC-based circuit that converts the sensor millivolt signal into standard voltage, current or RS485 outputs for direct connection to interface cards, control instruments, smart devices or PLCs. Long-distance transmission is supported via current output. Designed for industrial process use with an all-stainless-steel sealed housing, the LFT2030 provides high temperature resistance via heat-sink configurations and is suitable for corrosive environments.

Key features

• Heat-sink integrated with sensing core enables stable operation at elevated medium temperatures (examples: 5‑fin: 180°C; 10‑fin: 260°C).
• ASIC and digital compensation for improved accuracy and stability.
• Stainless steel wetted parts and elastomer options for corrosion resistance.
• Strong EMI immunity and long-term stability <0.5% F.S./year.
• Threaded pressure connection for straightforward installation; IP65 enclosure.
