High quality WIKA S-20 pressure transmitter pressure sensor for general industrial applications

product description

The S-20 pressure converter for general industrial applications is the ideal solution for users with high measurement requirements. With high accuracy, the transmitter is not only rugged but also available in a variety of versions to meet the requirements of a variety of applications.

Model S-20 transmitters are available from.. 0.04 MP.. Different measuring ranges of 60 MPa support all common pressure units. This transmitter supports all standard industrial output signals and is equipped with international process connectors and various electrical interfaces, allowing users to choose from different measurement ranges. In addition, the model transmitter offers options such as different accuracy levels, extended temperature range, and custom pin assignments.

The S-20 pressure transmitter is a durable design of exceptional quality that enables it to function even in the harshest environmental conditions. This type of transmitter can meet the requirements of all applications, whether it is outdoor low temperature conditions, mechanical manufacturing severe shock and vibration environment, or chemical industry corrosive media.

Applications

• Critical industrial applications
• Demanding applications in research and development
• Harsh environments in the process industry

specification

Special Features

• Measuring ranges from 0 ... 0.4 to 0 ... 1,600 bar
• Non-linearity up to 0.125 % of span
• Different output signals, e.g. 4 ... 20 mA, DC 0 ... 10 V, DC 1 ... 5 V and others
• Market-standard electrical connections, e.g. DIN 175301-803 A angular connector
• Common international process connections

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.

Relationship to the mounting position

For measuring ranges < 1 bar (15 psi), an additional zero offset of up to 0.15 % applies.

Non-repeatability

≤ ±0.1 % of span

Temperature hysteresis

0.1 % of span at > 80 °C (176 °F)

Long-term drift (per IEC 61298-2)

■ ≤ ±0.1 % of span

■ ≤ ±0.2 % of span (with special measuring ranges and measuring ranges < 1 bar (15 psi)).

Temperature error (for calibration temperature 15 ... 25 °C (59 ... 77°F))

For measuring ranges < 1 bar (15 psi), special measuring ranges and instruments with an increased overpressure limit the respective temperature error increases by 0.5 % of span.

Mounting position: Calibrated in vertical mounting position with pressure connection facing downwards.
