The Haoying PT112/PT123/PT133 series high‑temperature melt pressure sensors provide 0–2000 bar range, ±0.25%FS accuracy, and selectable output signals.
The PT112/PT123/PT133 series are high‑temperature melt pressure sensors designed for measuring and controlling melt pressure in chemical fiber and rubber‑plastic equipment. They feature stainless‑steel housing, internal calibration, and simple installation.
Technical data include a pressure range of 0‑2000 bar, accuracy of ±0.25%FS (or ±0.5%FS), 10 VDC supply, and selectable output signals of 1.5, 2, 2.5 or 3.33 mV/V. Options for 6‑pin or 8‑pin connectors, various hose lengths, and temperature‑compensated RTD types are provided. This manual is written in Chinese.

They can measure from 0 bar up to 2000 bar (0–3.5 MPa–200 MPa).
The sensors operate from a 10 VDC supply.
Output can be selected as 1.5 mV/V, 2 mV/V, 2.5 mV/V or 3.33 mV/V.
The sensor is offered with either a 6‑pin or an 8‑pin connector.
