Overview
The Georg Fischer 3-2450-7U (part number 159000906) is a Signet 2450 series pressure sensor designed for reliable pressure monitoring in industrial process control and fluid management applications. This sensor combines corrosion-resistant construction with accurate, drift-free measurement in a compact union-mounted package.
Key Features
- One-piece injection-molded PVDF body with ceramic diaphragm for superior chemical resistance
- Solid-state circuitry eliminates internal drift (no potentiometers to calibrate)
- Built-in temperature compensation for consistent accuracy across -15°C to +85°C operating range
- Industry-standard 4-20mA analog output for direct PLC/data acquisition integration
- 1/2″ threaded male union process connection allows quick, field-serviceable installation
- Pre-wired with 15ft (4.6m) shielded 3-core 22AWG cable with flying leads
