Series 642 programmable HART® field temperature transmitter


The Series 642 programmable 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 642 can be programmed with a PC or a HART® protocol handheld terminal. When supplied with a digital display, the LC screen shows the current measured value and a bar graph with limit value violation indicator. 



Application Areas 

• Temperature field transmitter with HART® protocol for converting various input signals to an analog, scaleable (4 to 20) mA output signal 
• Input: Resistance thermometer (RTD) Thermocouples (TC) Resistance input (Ohm) Voltage input (mV) 
• HART® protocol for operating the device on site using a handheld communicator or remotely via the PC
