FAQ

Q: What is the difference between the UPT-20 and UPT-21?
A: The UPT-20 uses a standard pressure port connection, while the UPT-21 features a flush diaphragm for hygienic or viscous media applications.

Q: Does the transmitter support digital communication?
A: Yes. In addition to the standard 4-20 mA analog output, the UPT-20 can support HART® communication.

Q: Can the display be rotated after installation?
A: Yes. The housing can rotate and the display position can be adjusted for optimal visibility.

Q: Which industries commonly use the UPT-20?
A: It is widely used in chemical plants, pharmaceutical production, food processing and general industrial process control.
