Spriano

Founded in the early years of the 20th century, Spriano® is a leading brand in the measurement, indication, transmission, and control of industrial processes.
Pressure and temperature gauges, along with inclinometers designed by Spriano®, are considered crucial instruments for the safety of the control panel during navigation, and were chosen by the engineers of the SSK S-506 Toti, the first submarine to be built in Italy after World War II.
This submarine was a masterpiece of innovation and technology that re-launched the country’s shipbuilding industry (some instruments are still on display in the permanent section of the Leonardo da Vinci National Museum of Science and Technology in Milan).
In the 1980s, SPRIANO® completed its technological transition from pneumatic to electronic systems by developing a complete range of innovative instruments, including a 2-wire system and microprocessor-based electronics with both transmission and control functions.
Thanks to the high quality standards achieved with this instrumentation, Spriano® has had the opportunity to take part in various projects in more than 60 countries worldwide.
In addition to its well-established activities in Italy, Spriano® is also expanding its export operations in many foreign countries, managed by a well-trained and internationally selected sales network.

The transmitter series SST70 measures liquid levels, density and interface levels in closed or open vessels. It converts buoyant force exerted by a displacer immersed in a liquid to a proportional current signal thanks to a mechanical forces transmission device based on a torque tube and a piezoresistive sensor.
Inside the float is placed a magnet which drives, without contact, reed contacts located inside a pipe that can itself be the guide of the float. Moving along its guide pipe, the float changes the reed contact status.
The SST72 transmitters are able to accept 3 wires Pt 100 ohm resistance thermometers and total accuracy is depending on class of the sensors utilized such as DIN A, DIN B, 1/4 DIN, 1/10 DIN, etc.
SST77BL series SMART level transmitters are microprocessor based instruments that combine the analog signal advantages (4-20mA) together with the flexibility of digital communication using HART® protocol.
SST79B series SMART level transmitters are microprocessor based instruments that combine the analog signal advantages 4-20mA together with the flexibility of digital communication using HART® protocol.
