Promass S is at the forefront in hygienic design and dedicated to applications in the food and beverage industry requiring optimal cleanability. The self‐drainable single-tube system ensures careful treatment of fluids. With its compact transmitter Promass S 300 offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology ensures process safety at all times.
● Increased process safety – easily cleanable and fully self-drainable tube design
● Fewer process measuring points – multivariable measurement (flow, density, temperature)
● Space-saving installation – no in/outlet run needs
● Full access to process and diagnostic information – numerous, freely combinable I/Os and fieldbuses
● Reduced complexity and variety – freely configurable I/O functionality
● Integrated verification – Heartbeat Technology
● Measuring principle operates independently of physical fluid properties such as viscosity or density
● Dedicated to applications requiring optimal cleanability under hygienic conditions.
Device properties
● Large range of hygienic process connections
● 3-A and EHEDG conform
● Fast recovery from CIP/SIP
● Compact hygienic dual-compartment housing with IP69 and up to 3 I/Os
● Backlit display with touch control and WLAN access
● Remote display available
