This document is the specification sheet of COPAL P-8300 pressure transducer. It has double diaphragm structure, two pressure references, built-in temperature compensation function.
The P-8300 series pressure transducers feature a double‑diaphragm structure with selectable gauge or absolute pressure references and built‑in temperature compensation (0 ~ 50 °C). The manual lists the internal construction, including a silicone‑oil sealed liquid, stainless‑steel diaphragms (SUS 316L), ceramic compensation resistor board and gold‑plated terminal pins.
Standard specifications cover rated pressure ranges from 0 ~ 34.3 kPa up to 0 ~ 981 kPa, thermal error of ±0.05 % FS/°C, operating temperature –20 ~ 70 °C, excitation current of 1.5 mA DC, and a net weight of about 20 g. Environmental tests, outline dimensions, connection details, and installation examples are also provided.
| Pressure reference | Gauge or Absolute |
|---|---|
| Bridge resistance | 4700 Ω ±30 % |
| Offset voltage | +5 mV |
| Span voltage | 100 mV |
Extra care should be taken; do not touch the diaphragm directly to avoid damage.
