Series 645 Wet/Wet Differential Pressure Transmitter
Brand: Dwyer Instruments, LLC
Series 645 Wet/Wet Differential Pressure Transmitters are designed for use with compatible gases and liquids which can be applied to both the pressure and reference ports.
Quick response capacitance sensor delivers a 4-20 mA output signal proportional to differential pressure with ±0.25% accuracy.
The Series 645 transmitters are ideal for process control, filter condition monitoring, refrigeration equipment, pump speed control, HVac equipment, and liquid level measurement.
For ease of installation and maintenance, order optional 3-valve manifold assembly. Bleed ports allow for total elimination of air in the line and pressure cavities.
Features- Versatile, high-accuracy device for liquid or gas supports designs requiring more precise measurements in support of application
- Optional 3-way valve manifold supports simplifying installation or removal of transmitter without interrupting process
