Product Features

The ADDA-T-GW Series sanitary temperature transmitter uses RTD sensing for food, beverage, pharmaceutical, and bioengineering applications. It features an all-stainless-steel structure and a dot-matrix LCD module that supports 355° rotation. The hygienic design has no dead spaces and is designed to comply with FDA requirements. Key features include:

Sealed with silicone rubber or epoxy resin for vibration and moisture resistance; suitable for harsh operating environments.
High accuracy, low quiescent power consumption, stable and reliable operation, and long service life.
Hygienic design complies with EHEDG, 3A, FDA, and GMP requirements.
Wetted material surface roughness down to Ra 0.4.
Supports HART communication for local or remote parameter adjustment and monitoring through a handheld communicator.

Applications

Temperature measurement in food, beverage, pharmaceutical, and other sanitary applications.

Measuring Medium

Media compatible with the wetted materials.
