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.Features
