The WIKA UPT-20 and UPT-21 are universal process pressure transmitters that provide high-quality, intelligent pressure measurement for industrial applications. With options for a standard pressure port (UPT-20) or a flush diaphragm connection (UPT-21), these transmitters deliver precise output and flexible integration into process control systems.
Typical Applications:
• Process control and automation in chemical, petrochemical and HVAC systems
• Machine building and plant construction
• Pharmaceutical and hygienic industries
• Food & beverage process monitoring
• General industrial pressure feedback for PLC/DCS/SCADA systems
Not Recommended For:
• Very simple local indication without digital communication
• Applications where basic pressure sensors suffice
Models UPT-20, UPT-21 Data sheets
• Choose UPT-20 when a standard process connection is suitable
• Choose UPT-21 when hygienic or viscous media require a flush diaphragm
• Confirm signal output requirements (4–20 mA with HART® compatibility)
• Determine appropriate housing materials (conductive plastic, stainless steel or electropolished surface) based on environment and media
• Universal Integration: Output with 4–20 mA and HART® communication for process automation systems or analog loops.
• Intelligent Sensor Technology: Integrated temperature compensation and smart sensor features for reliable measurement across changing operating conditions.
• Flexible Process Connections: With standard pressure port (UPT-20) or hygienic flush diaphragm (UPT-21) options to suit various media and process requirements.
• User-Friendly Display: Large LC display with simple menu navigation and rotatable interface for easy local reading and configuration.
• Robust Design: Options including conductive plastic or stainless steel housing, with approvals for use in hazardous areas when required.
• Adjustable Turndown: Allows optimizing measurable range with minimal impact on accuracy.
Q: What is the difference between UPT-20 and UPT-21?
A: UPT-20 has a standard pressure port connection, while UPT-21 features a flush diaphragm ideal for hygienic, viscous, or sterile processes.
Q: Can these transmitters be configured on site?
A: Yes — the LC display and menu interface enable on-site readout and configuration, including range scaling and HART® settings.
Q: Are UPT-20/UPT-21 suitable for hazardous areas?
A: Yes — options and approvals exist for use in process environments requiring hazardous area certification.
Q: What communication options are available?
A: They support 4–20 mA analog plus HART® digital communication for integration with PLC/DCS or asset management systems.
