Series 642 Programmable HART® Field Temperature Transmitter

Brand: Pyromation
Does not ship to OH, United States
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.
Features
  • Universally programmable with HART® protocol for various input signals
  • Illuminated display, rotatable
  • Operation, visualization and maintenance with PC
  • 2-wire technology, analog output (4 to 20) mA
  • Undervoltage detection
  • Highly accurate in entire operating temperature range
  • Approvals: FM and CSA (IS, NI, XP and DIP)
  • Galvanic isolation
  • Output simulation
  • Min./max. process values recorded
  • Customized measuring range setup or expanded setup
