Description

Instrument construction
The model UPT-2x process transmitter has been developed for applications which require an intelligent sensor. Particularly the integrated temperature compensation makes the process transmitter interesting for a wide range of applications.

The measuring cell is made of stainless steel 316L or of a combination with high-quality Elgiloy. For specific requirements, further special materials are available.

The case is rotatable by 330 and the LC display can be mounted in different positions, displaceable in 90 steps. The LC display is easy to read in any mounting position, even from a distance of up to 5 m.

HART protocol
The process transmitter can be installed both in applications using analogue technique and modern systems communicating via the HART protocol.

Via the display and operating module or the HART interface this process transmitter can be configured directly on site or remotely via a process control system.

Turndown
An adjustable turndown (20:1) allows to register exact process values with optimised limits of the measuring.

Intelligent Pressure Measurement Simplified

Designed with industrial flexibility in mind, the WIKA UPT-20 offers tailored functionality for process monitoring and control. The display is large, backlit, and rotatable, enabling easy visibility from different angles. Users benefit from robust ingress protection (up to IP68) and explosion-proof certifications, making it suitable for hazardous areas. Multiple electrical connections and material options allow seamless integration into existing systems.

Versatile Configurability and Connectivity

The UPT-20 is compatible with both local and remote zero adjustment through its intuitive display or via the HART interface. Output signals are fully configurable to fit any process requirement. Damping can be adjusted to stabilize readings, while the device's supply voltage range (10.5-45 V DC) ensures compatibility with various control systems. Standardized threaded and optional flange connections simplify installation across industries.

FAQ's of Wika Process transmitter UPT-20:

Q: How do I configure the output signal and display settings on the UPT-20 transmitter?

A: The UPT-20 allows configuration via its integrated keypad and backlit, rotatable LCD display, as well as remotely through the HART protocol. You can adjust the output signal (4-20 mA), change display orientation, and set parameters such as damping and zero adjustment according to your application needs.

Q: What makes the WIKA UPT-20 suitable for hazardous or demanding environments?

A: The transmitter is available with ATEX and IECEx explosion protection certifications, has ingress protection up to IP68, and is constructed from stainless steel (316L) with robust sealing options. These features make it ideal for use in chemical, petrochemical, oil & gas, and other industrial environments requiring high safety and durability standards.

Q: When should I use the UPT-20 for absolute, gauge, or vacuum pressure measurement?

A: You should select the UPT-20 model that matches your application's measurement type. It covers gauge, absolute, and vacuum pressure ranges, making it versatile for monitoring atmospheric deviation, tank levels, or process vacuum and overpressure scenarios in industrial settings.

Q: Where can the UPT-20 process transmitter be installed?

A: The UPT-20 can be mounted directly onto the process line through a 1/2" BSP threaded connection or other available options. Its sturdy design and IP-rated housing allow installation outdoors or in hazardous industrial areas, provided proper installation guidelines are followed.

Q: What is the typical adjustment process for zero and damping on the UPT-20?

A: Both zero point and damping parameters can be conveniently set via the local display's keypad or using HART communication. These adjustments help tailor the transmitter's response time and baseline value to your process requirements for optimum accuracy and stability.

Q: How does the UPT-20 benefit industrial process control and safety programs?

A: By providing accurate and reliable pressure measurements with rapid response (<10 ms), configurable output, and local/remote adjustment, the UPT-20 supports process optimization, safe operations, and compliance with CE, RoHS, and Ex standards. Its robustness and user-friendly interface facilitate maintenance and minimize downtime.
