WIKA Models IPT-20 and IPT-21 process transmitters
$120.00
The WIKA IPT-20 and IPT-21 are industrial process transmitters with welded metal measuring cell, designed for demanding process pressure measurement and integration into modern automation systems. They offer robust performance with multiple output options — including analog, HART®, PROFIBUS® PA, and FOUNDATION Fieldbus™ — and extensive configuration flexibility.
Typical Applications:
• Chemical and petrochemical industries
• Process engineering and food & beverage production
• Pharmaceutical manufacturing
• Hazardous areas requiring certified devices
• Automated control systems requiring high precision pressure feedback
Not Recommended For:
• Very simple local indication without remote communication needs
• Low-cost, basic pressure measurement where automation integration is unnecessary
Selection Notes
• Confirm your required output protocol — 4 … 20 mA, HART®, PROFIBUS® PA, or FOUNDATION Fieldbus™
• Choose whether you need a pressure port (IPT-20) or flush diaphragm (IPT-21) variant for hygienic applications
• Verify hazardous area certification requirements (ATEX/IECEx) and SIL suitability
• Configure using EDD/DTM and FDT tools such as PACTware™ for easy integration within control systems
Why Choose WIKA IPT-20 / IPT-21 Process Transmitters
• Full Protocol Support: Offers standard 4 … 20 mA, HART®, PROFIBUS® PA, or FOUNDATION Fieldbus™ output for versatile process integration.
• Extensive Pressure Ranges: From very low pressures to extremely high (e.g., 0 … 0.1 bar up to 0 … 4,000 bar), with freely selectable turndown for flexible span configuration.
• Robust Welded Cell: Welded metal measuring cell ensures high durability and compatibility with aggressive media.
• Configuration Flexibility: Parameterisation via on-site display panel or PC tools like PACTware™ accelerates commissioning and diagnostics.
• Seven Case Variants: Multiple housing options (plastic, aluminium, stainless steel, electropolished 316L) to suit industrial, sanitary, or hazardous environments.
• Hygienic or Standard Process: The IPT-21 variant with flush diaphragm is especially suited to food, beverage, and pharmaceutical applications requiring sanitary conditions.
FAQ
Q: What is the difference between IPT-20 and IPT-21?
A: IPT-20 uses a pressure port for general industrial applications, while IPT-21 has a flush diaphragm ideal for hygienic media or viscous fluids.
Q: Can these transmitters be used in hazardous areas?
A: Yes — both models support ATEX and IECEx ignition protection types and suitable designs for SIL2/3 applications.
Q: How can I integrate these into my control system?
A: Choose from analog signal (4 … 20 mA) or fieldbus protocols (HART®, PROFIBUS® PA, FOUNDATION Fieldbus™) based on your automation strategy.
Q: Is configuration via PC supported?
A: Yes — parameters can be set with PACTware™ through EDD/DTM integration, simplifying field configuration.
