Description
The model S-20 pressure transmitter is the ideal solution for customers with demanding performance requirements in many industrial applications.
It features high accuracy, a robust design and is available with an exceptional number of options that make it suitable for an extremely broad range of pressure measurement applications. .
High versatility
The model S-20 oers continuous measuring ranges between
0…10 psi and 0…20,000 psi (0 ... 0.4 and 0 ... 1,600 bar) in all common engineering units. Vacuum and compound ranges are also available.
These measuring ranges can be combined with virtually any standard industry output signal, common international process connections and a wide variety of electrical connections.
A large number of options are available including dierent
accuracy classes, extended temperature ranges and
customer specic pin assignments to provide compatibility
with most industrial applications.
Data sheets showing similar products: Pressure transmitter for general industrial applications; model A-10; see data sheet PE 81.60
High quality
The rugged design makes the model S-20 a highly reliable
transmitter that is not aected by most adverse environmental
conditions. This transmitter meets most application performance requirements when exposed to very low outdoor temperatures, extreme shock and vibration and aggressive media.
Availability
Variations of the S-20 described in this data sheet are usually available with short lead times. Inventory of popular designs are usually available for particularly urgent requirements.

The listed pressure ranges are also available in kg/cm2, kPa and MPa. Special measuring ranges between 0 ... 10 and 0 ... 20,000 psi ( 0.4…1600 bar) are available on request. Special pressure ranges may have reduced long-term stability and increased temperature errors.
Overpressure limit
The overpressure limit depends on the specic sensor element used for the selected pressure range. A reduction in the overpressure safety rating may occur depending on the specic process connection and seal selected. A higher overpressure
limit may provide a greater temperature error.
