Fischer pressure transmitter Building technology Differential Pressure Transmitter DE16
Application
Measuring transmitter for overpressure, partial vacuum and differential pressure. This series is suitable for various measuring applications in the field of in-
dustrial and sanitary techniques.
Typical applications:
Measurement of differential pres-sure between forward- and return-flow in heating systems. Monitoring of filters, blowers and compressors.
Main Features
Overpressure protection, Rugged design. Maintenance and wear free inductive pick-up Multiple applications.
