IFM PA3020 Pressure Transmitter 0-400bar 4-20mA G1/4 IP68 IP69K

Overview
The IFM PA3020 (PA-400-SBR14-A-ZVG/US/ /V) is a high‑precision pressure transmitter with a ceramic capacitive measuring cell, designed for reliable relative pressure measurement in liquids and gases. Featuring a measuring range of 0…400 bar (0…5800 psi / 0…40 MPa) and a precise linear 4…20 mA output signal, this loop‑powered transmitter delivers exceptional performance for demanding industrial applications. The ceramic measuring cell offers high overload protection (pressure rating 600 bar, min. bursting pressure 1000 bar) and long‑term stability (< ±0.05% of span per 6 months). The robust stainless steel (316L) housing with gold‑plated contacts and G 1/4 internal thread process connection withstands harsh industrial environments. Rated IP68 and IP69K, the transmitter is dust‑tight, resistant to continuous immersion, and withstands high‑pressure, high‑temperature washdowns. With high repeatability (< 0.1% of span), low linearity error (< ±0.25% BFSL), wide operating temperature range (-25…80°C ambient, -25…90°C medium), and response time of 3 ms, the PA3020 is suitable for hydraulic systems, industrial machinery, process automation, and food & beverage applications requiring high‑pressure monitoring.

Key Features
