PA-838-D series pressure transducer is a product with high corrosion resistance and drip-proof construction. The measuring pressure range is 0~10kPa, 0~50kPa, 0~100kPa, and the joint types are Rc 1/4 and 1/4 Flare fitting(7/16-20 UNF).
The PA-838-D is a pressure transducer with built‑in amplification, featuring high corrosion resistance and a drip‑proof IP‑65 rated gauge body. It is available with Re 1/4 or 1/4 flare fittings and uses a stainless‑steel diaphragm (SUS 316L) sealed with silicone oil.
The datasheet lists rated pressure ranges of 0‑10 kPa, 0‑50 kPa, and 0‑100 kPa, with maximum pressures up to 500 kPa. Electrical specifications include a 24 V DC supply (±10 %), 4‑20 mA output, and a linearity/hysteresis of ±0.5 % FS. Environmental tests cover vibration, shock, moisture resistance, and temperature ranges from –20 °C to 70 °C.
