RTD sensors for temperature measurement in pipes, bioreactors, vessels or tanks are recommended for critical sterile and general applications in the life sciences and food industries. RTDs provide accurate and reliable data for safe operations in upstream, downstream, utilities, sterilization (SIP), cleaning (CIP) and production processes, including fermentation, steam generation, production of water for injection (WFI) purified water for pharmaceutical use (WPU) and more.

What is an RTD and how does it work?

Resistance temperature detectors, or RTDs, are sensors commonly made of a platinum element that experiences a change in electrical resistance when the temperature changes. RTDs for process temperature measurement are typically highly accurate and long-term stable within a temperature range of -200 °C to +600 °C. The most commonly used RTD types are Pt100 or Pt1000. As a standard, Endress+Hauser RTD sensors are at minimum Class A according to IEC 60751.
