Description

MEASURING PRINCIPLE AND FEATURES 

ST thermometers are probes for the temperature measurement with a Platinum thermistor Pt100 1/3DIN (100Ω@0°C). The change in resistance of the Pt100 is transformed into a signal of current or voltage linear with temperature.

All sensors are provided with shielded and waterproof cable that allows the use in the most different applications linked to the environmental monitoring, hydrology and industrial.

ST sensors are available in two versions: with natural Pt100 with 4 wires output (Vers. –N) or 4…20mA (Vers. –I).

 

ADVANTAGES

  • Versatility of use
  • Mechanical ruggedness 
  • Reliability
  • Lifetime
