PTX

Standard-screw-in resistance thermometer Pt100 with and without neck tube for EX-range

  • ATEX-approval
  • Large selection of variants
  • Measuring insert can be changed separately

 

Description

Fundamentals of ACS Universal resistance thermometer are standardized, high-quality platinum RTDs of a nominal resistance of 100 ohms at 0 ° C, tolerance classes A, B, 1/3B (AA) – in accordance with DIN EN / IEC 60751st.

ACS Pt100 probes have a high accuracy and reproducibility are ​​extremely reliable.

PTX-resistance thermometers are approved for gas and dust explosion requirements, and are generally delivered with exchangeable measuring insert Pt100. Thus, the actual sensor may be removed from the probe tube and possibly replaced without draining the pipe or the container. This saves costs and avoids loss of production.
