Temperature Transmitter

Temperature TransmitterApplication

The Alfa Laval temperature transmitter is designed to fulfil the demands in sanitary and pharmaceutical production.

The main features are:

  • Wetted parts in AISI316L, stainless steel
  • Compact, and hygienic design (3A / FDA and EHEDG compliant)
  • Measuring range: -20 to 150°C
  • Build-in transmitter with 4-20 mA output
  • High accuracy

Standard range

The Alfa Laval temperature transmitter features as standard a stainless steel field housing in excellent finish, suitable for sanitary applications. All process connections are as standard hygienic connections with high cleanability and bacteria tightness, as an option wetted parts can be electropolished down to Ra >0.4µm. The design of the sensor tip ensures low response times and accurate measurements. The output can be supplied either as a standard 4-20 mA, 4-20 mA/HART® output or Profi bus® DP interface.

Working principle

The Alfa Laval temperature transmitter relies on a fast response Pt100 sensor tip. The sensor element is as standard a DIN A sensor element which is connected with 4 wires to the build in transmitter. This ensures full resistance compensation and enables reliable and accurate measurements of process temperatures with a standard analogue output of 4-20 mA.
