Series 662 Programmable HART® Dual Input Field Temperature Transmitter

Brand: Pyromation

The Series 662 programmable dual input HART® field temperature transmitter is a 2-wire unit with analog output.

It includes input for RTDs; resistance inputs in 2-wire, 3-wire, and 4-wire connections; thermocouples and voltage signals.

The transmitter can be supplied with or without a digital display, in either a general-purpose aluminum housing, or explosion-proof aluminum housing.

The Series 662 can be programmed with a PC or a HART® protocol handheld terminal. When supplied with a digital display, the LCD screen shows the current measured value and a bar graph with limit value violation indicator.
