absolutepiezoresistive4-20 mA

Product overview
The LFT6200 is an isolated explosion-proof pressure transmitter for industrial gas and liquid pressure measurement (water, oil, mildly corrosive media). It features a 304 stainless-steel pressure head, a high-quality sensing element and a dedicated V/I conversion circuit for easy zero and span calibration. The unit is certified Exd IIc T6 Gb and offers multiple electrical and pressure-connection options.

Features

• Exd IIc T6 Gb explosion-proof construction.
• 304 stainless-steel pressure head (316L compatible option).
• Selectable pressure ranges from -100 kPa up to 60 MPa.
• Multiple output signals: 4–20 mA, 4–20 mA + HART, 0–10 VDC, RS-485.
• Configurable live display and various pressure connections (M20×1.5, G1/2).
• IP67 enclosure with waterproof cable outlet.
