PA-858 pressure transducer is a pressure sensor produced by COPAL ELECTRONICS. It features high corrosion resistance and drip-proof design.
The PA-858 series provides pressure transducers with built‑in amplification, featuring a drip‑proof IP‑65 rated stainless‑steel housing (SUS 316L) and three standard joint types (R2, GF, G2). The devices support absolute, gauge and vacuum pressure references and can handle both positive and negative pressures.
Technical data include a 4–20 mA output, 24 V DC supply (±10%), operating temperature from –20 °C to 70 °C, and a net weight of approximately 180 g. Various model numbers cover rated pressure ranges from 0‑100 kPa up to 0‑1000 kPa, with maximum pressures up to 2000 kPa for the 103 model.
