Miniature Two-Wire Transmitters with
Full-Size Performance

Despite their tiny size and economical price tag, ST130 units are full-featured. By leveraging the latest signal conditioning technologies, these transmitters are able to provide a performance level and feature set previously unavailable in a unit of this size and price.

High Performance Temperature Sensor Signal Conditioners

  • Thermocouple (J,K,T,R,S,E,B,N), Pt RTD, ±100mV, or 0-100 ohm input
  • High Accuracy and Linearity with Low-Drift 4-20mA output
  • ast and Easy Software Configuration via USB Connection

Advanced Technology in a Rugged Design

  • New microcontrollers and ASICs minimize conversion errors
  • Fast response and flexible input/output ranges
  • No messing with adjustment pots, switches, or pushbuttons
  • High immunity to surges, electrical noise, shock, and vibration 
  • -40 to 80°C operation
  • UL/cUL Class 1 Div 2 Zone 2 approval pending
