Dew Point Sensor down to -70 °C Td (-94 °F Td)
The compact TDS501 sensor measures dew point temperature (Td) down to −70 °C (-94 °F). It is designed for very low
humidity levels where even small changes are critical for product quality and process stability. Along with Td, the sensor
provides other humidity-related measurands such as frost point temperature (Tf) and volume concentration (Wv).
Innovative Measurement Method
The core of TDS501 is the new E+E Quattro Sensor technology which combines four robust in-house developed and
manufactured capacitive sensing elements in a continuously measuring system. The technology allows for in-line process
montoring without interuption, while the sensor system is still able to perform periodic auto-calibrations to ensure reliable
and long-term stable measurements.
Functionality and Robustness
The extremely robust stainless steel construction and filter options ensure dependable operation even under harsh
conditions. TDS501’s wettable sensing elements withstand temporary condensation which can occur during dynamic load
changes or at start-up.
Fast Response Time and Process Reliability
The TDS501 responds immediately to dew point changes at all times, without any output freeze during auto‑calibration.
Stainless steel filter options provide an optimal balance of protection and response speed. For applications requiring
maximum dynamics, such as in cleanrooms, an optional open filter cap option further accelerates the response time.
High Accuracy and Long-term Stability
High repeatability and an accuracy of ±2 °C Td enable the TDS501 to reliably monitor processes where the dew point is a
key parameter. The E+E Quattro Sensor technology minimises the risk of drift and maintains measurement stability, even
during temperature changes or abnormal operating conditions. This supports consistent performance in dry environments,
improved yield and the early detection of system deviations.
Interface and Configuration
The TDS501 sensor integrates easily into industrial environments through both, analogue and digital interfaces.
With a pressure rating of up to 80 bar, it can be installed directly in high‑pressure compressed‑air systems. Use the free
PCS10 Product Configuration Software and the optional adapter for configuration and adjustment of the TDS501.
