Product Overview
The Dwyer Series 645 Wet/Wet Differential Pressure Transmitter is a high-precision instrument designed for measuring differential pressure in compatible gases and liquids. Featuring a quick-response capacitance sensor, it delivers a 4-20 mA output proportional to pressure changes with ±0.25% accuracy.
The 2-wire design simplifies installation, while bleed ports in the optional 3-valve manifold allow air elimination for reliable readings. Ideal for process control, filter monitoring, HVAC systems, and liquid level measurement, this transmitter combines rugged performance with ease of maintenance for industrial applications.
Key Features
- High-Accuracy Measurement: ±0.25% full-scale accuracy ensures precise differential pressure monitoring with fast response capacitance sensor
- 2-Wire Design: Simplifies wiring and reduces installation costs in industrial setups
- Wet/Wet Compatibility: Suitable for both gas and liquid media on pressure and reference ports
- Versatile Applications: Process control, filter monitoring, refrigeration equipment, pump control, HVAC, and liquid level measurement
- Optional 3-Valve Manifold: Enables easy installation and maintenance with bleed ports for air elimination
- Reliable Performance: Robust construction with stainless steel components for long-term industrial use
