WIKA UPT-20 and UPT-21 Universal Process Transmitter with Digital Display

WIKA's new UPT-2X process transmitter has been developed for applications that require integrated temperature compensation and an intelligent sensor. It can be used with its standard 4-20 mA two-wire output, or with the optional HART® 7 communications protocol. The programmable, rotatable LCD display features 4-1/2 digits, a round bargraph, plus operating state symbols, and can be read at a distance up to 16 feet away.

The intrinsically safe version of the transmitter is particularly well suited for use in chemical plants and hazardous areas. The flush diaphragm UPT-21 fits the requirements of hygienic, pharmaceutical, and food industry applications.
