Series 442 Programmable HART® Temperature Transmitter

Brand: Pyromation
Does not ship to OH, United States
The Series 442 programmable HART® temperature transmitter is a 2-wire transmitter with an analog output.
 
It has measurement input for resistance thermometers (RTD) in 2-, 3- or 4-wire connections, thermocouples, resistance and voltage inputs. The transmitter can be programmed with a PC or HART® protocol hand-held terminal. 
 
These small units can be mounted in Pyromation DIN (Form B) connection heads, or they can be used for surface mounting by using a 35 mm DIN-rail mounting clip.

Features

  • Universal settings with HART® protocol for various signals.
  • Galvanic isolation
  • 2-wire technology, (4 to 20) mA analog output
  • High accuracy in total ambient temperature range
  • Fault signal on sensor break or short circuit
  • RFI/EMI Protected, CE marked
  • cURus, UL Recognized Component
  • FM Intrinsically safe and non-incendive for hazardous locations
  • Output simulation
