Single Pressure Transmitters
The Series 672 Low Pressure Transducer is a perfect solution to any The Series 672
Low Pressure Transducer is a perfect solution to any application where a very accurate
low pressure transducer is necessary. Using variable capacitance technology, the
Series 672 is designed to measure pressures as low as 10 in w.c. up to 400 in w.c.,
very low ranges for a single connection pressure transducer. The 672 also features
a 0.25% FS accuracy. Use the Series 672 in liquid level, ood warning, waste water,
clean room, and open channel ow applications.
FEATURES/BENEFITS
• Low range high accuracy provides precise control for process applications
APPLICATIONS
• Liquid level
• Flood warning
• Waste water
