The manual provides specifications, ordering information, and connection details for Haoying PT112D/PT123D/PT133D high‑temperature melt pressure sensors.
This document describes Haoying’s PT112D, PT123D and PT133D series high‑temperature melt pressure sensors, which are used for measuring and controlling melt pressure in synthetic fiber and rubber‑plastic equipment. The sensors feature simple installation, multiple output options, and compatibility with international products.
Key specifications include a pressure range up to 2000 bar, accuracy better than ±0.5 %FS, 10 V DC supply, and selectable output signals from 1.5 mV/V to 3.33 mV/V. The series offers different mechanical configurations (straight rod, rod + flex hose) and temperature‑resistant membranes up to 400 °C. This manual is written in Chinese.
