Why Choose the Differential Pressure Sensor?
Timely Filter Replacement
Differential pressure monitoring allows filters to be replaced at the right time – neither too early nor too late. A filter element replacement is recommended when the differential pressure exceeds 350 mbar (except for activated carbon filters).
Reduced Energy Costs
Increasing differential pressure results in higher energy consumption and increased operating costs. Continuous monitoring helps prevent unnecessary losses and optimize system performance.
High Measurement Accuracy
The sensor achieves a total error of only 2% of full scale and provides reliable differential pressure measurements up to 1.6 bar.
Industrial 4–20 mA Output
The standard two-wire 4–20 mA output enables easy integration into monitoring systems, data loggers, and existing industrial automation solutions.
Suitable for Harsh Environments
Designed for industrial use, the sensor operates in temperatures ranging from −20 to +80 °C and withstands system pressures up to 10 bar.
Easy Installation and Operation
G 1/8" connections with push-in fittings for 6 mm tubing and an M12 × 1 electrical connector ensure quick and reliable installation in existing systems.
Maintenance Cost Optimization
The chart provided in the brochure clearly illustrates the relationship between differential pressure, energy costs, and filter costs, making the sensor an essential tool for economical maintenance optimization.
