Dwyer Series 645 Wet/Wet Differential Pressure Transmitter (645-x)
Product Introduction
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.
Product Features
