This document introduces Copal Electronics' PA-860/PA-868 pressure transducers, which have a built-in amplifier circuit and can provide voltage or current output.
The PA-860 and PA-868 are pressure transducers equipped with built‑in amplifiers. They are offered with voltage (PA-860) or current (PA-868) output modes and feature stainless‑steel diaphragms, silicone sensor chips and optional drip‑proof covers.
Key specifications include supply voltage of 12‑24 V DC (±10 %), output ranges of 1‑5 V or 4‑20 mA, rated pressure ranges from 0‑10 MPa up to 0‑35 MPa, and an operating temperature range of –10 °C to 75 °C. The devices are designed for hydraulic oil pressure measurement and meet IP‑65 protection when the drip‑proof cover is installed.
