WIKA UPT-20 HART pressure transmitter

Click2Contact

The WIKA UPT-20 is a HART pressure transmitter featuring HART 7 firmware and a large LCD 4½-digit 14 mm display. The main 14 mm display in accompanied by a second three-line display and a radial bar graph which mimics an analog display for immediate value recognition.

Configuration and electrical installation can be done without tooling with range turndown up to 20:1. Pressure ranges on the UPT are available from 20 mbar up to 1000 bar with accuracy as low as 0.1%. Application has been made for IECEx, ATEX, FM, CSA and GOST hazardous approvals suitable for EX ia potentially explosive applications, expected later in 2014.

The device has all stainless steel wetted parts with no O-rings, making it suitable for most harsh process materials. The UPT-20 can also be used with diaphragm seals of exotic materials extending its versatility. An integrated stainless steel flush diaphragm is available with the UPT-21 for applications where the process may block the pressure inlet.

With a standard 4-20 mA/HART output signal and programming features displaying pressure, volume and level the UPT range of transmitters will be suitable for most liquid- and gas-monitoring applications and process control.
