Type 680 - Pressure Transmitter

Pressure Transmitter

Technical overview

» The pressure transmitters of type 680 with pie zoresistive measuring elements have    compensated, calibrated and amplified sensor signals which are available as standard    voltage or current outputs.
» The transmitter housing is available with various pressure and electrical connections.
» Manufactured from stainless steel, its welded construction provides a watertight seal.
» With its sophisticated building block system, individual designs to meet specific    applications are possible.

Advantages

» Effective overload protection due to chemically etched chip diaphragm and specially    designed glass gland
» Fast and affordable customer-specific solutions due to building-block system, even for    small quantities
» Compact construction with SMD technology enhances operational reliability in the    presence of shock and vibration
» Welded construction provides 100% sealing against media
