Description
The model S-20 pressure transmitter for general industrial applications is the ideal solution for customers with demanding measuring requirements. It features a very good accuracy, a robust design and an exceptional number of variants, meaning it can be suited to the widest range of applications.
Versatile
The model S-20 offers continuous measuring ranges between 0 ... 0.4 and 0 ... 1,600 bar in all the major units.
These measuring ranges can be combined in almost any way with all the standard industry output signals, the most common international process connections and a wide number of electrical connections.
Furthermore, it offers numerous options, such as different accuracy classes, extended temperature ranges and customer-specific pin assignments.
High quality
The robust design turns the model S-20 into a very high quality product, which even the most adverse environmental conditions cannot affect. Whether with the lowest temperatures when used outdoors, with extreme shock and vibration in machine building or with aggressive media in the chemical industry, this transmitter can meet all requirements.
Availability
All variants described in this data sheet are available on very short lead times. For particularly urgent demands, there is a sizeable stock available.
Measuring ranges
The given measuring ranges are also available in kg/cm2, kPa and MPa.
Special measuring ranges between 0 ... 0.4 and 0 ... 1,600 bar are available on request.
Special measuring ranges have a reduced long-term stability and increased temperature errors.
Overpressure limit
The overpressure limit is based on the sensor element used. Depending on the selected process connection and sealing, restrictions in overpressure safety can result. A higher overpressure limit will result in a higher temperature error.
Measuring range < 10 bar/150 psi ≥ 10 bar/150 psi
3 times (standard) 2 times 1) (standard)
