The ST131 is a low-cost two-wire transmitter that converts a 100 ohm Platinum RTD sensor input to a proportional 4-20mA signal. Power is received from the output loop current. The transmitter provides sensor excitation and includes linearization, lead-wire compensation, and lead-break detection functions. Setup and calibration are fast and easy with a convenient USB connection to your PC and Acromag’s Windows configuration software.

Advanced signal processing capabilities, variable range input, and convenient USB programming make this instrument a very versatile temperature transmitter for RTD and resistance elements. These transmitters are designed to withstand harsh industrial environments and operate reliably across a wide temperature range with very low drift. They feature RFI, EMI, ESD, EFT, and surge protection plus low radiated emissions.

  • Easy setup and digital calibration via USB with Windows configuration software
  • Flexible RTD or linear resistance input ranges
  • High accuracy and linearity
  • Advanced analog signal conditioning ASIC eliminates digitization errors
  • Low temperature drift
  • Fast response time (< 500µS)
  • Programmable over/under-range limits
  • Selectable upscale or downscale operation for sensor errors and lead-break detection
  • NAMUR NE43 compliant fault response
  • Reverse polarity protected with non-polarized output
  • Mounts in DIN Form B sensor heads
  • Optional DIN rail adapter
  • Wide ambient operation (-40 to 80°C)
  • Hardened for harsh environments
  • CE compliant. UL/cUL Class 1 Div 2 Zone 2 approvals. Ex II 3 G Ex nA IIC T4 Gc -40°C Ta +80°C
