Product Description
Product Description
The S-20 pressure transmitter has a wide range of applications and can meet the requirements of demanding tasks and harsh environments. The measurement range is 0 0.04 to 0 160 MPa [0... 5.8 to 0... 23200 psi], can be combined with various output signals, electrical connections, and process connections. These configuration options offer over 1 billion versions, providing ample room for customization. S-20 is also suitable for critical industrial applications and can reliably operate under high temperature, vibration, or corrosive media conditions.
The pressure measurement of S-20 is particularly accurate and reliable, with three accuracy levels to choose from. The temperature can be adjusted to+4 ° C,+40 ° C,+60 ° C, and+80 ° C [+39 ° F,+104 ° F,+140 ° F,+176 ° F] to minimize temperature errors.
S-20 adopts mature technology that has been tested and validated through practical experience. It has up to 100 million load cycles and long-term stability of less than 0.1%, providing accurate data for processes and equipment sustainably. In addition, regular reviews can permanently ensure the highest quality standards.

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.
Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.
Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.
Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
