The TD2831 is a 100 mm hygienic temperature transmitter designed for deeper process temperature measurement. It uses a Class A Pt1000 sensing element and provides an integrated four-digit LED display. The device combines 4–20 mA analogue output with IO-Link communication for automation systems. Its hygienic clamp connection and electropolished stainless-steel wetted surfaces support sanitary process environments. The 100 mm installation length makes it suitable for tanks, vessels, and process piping requiring deeper sensor insertion.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
TD2831 provides reliable continuous process temperature measurement. Its 100 mm installation length provides deeper sensing capability. Local display indication simplifies operator monitoring. IO-Link supports configuration and diagnostic access. The transmitter is suitable for automated process-control systems.
The Pt1000 Class A element provides stable measurement. The measuring range is -50...150 °C. The 4–20 mA output provides standard controller integration. IO-Link provides digital process communication. The analogue resolution is 0.04 K and display resolution is 0.1 K.
The clamp connection supports sanitary process installation. Wetted parts are electropolished 316L stainless steel. The design is suitable for liquid and gas media. The 100 mm probe supports deeper measurement points. High protection and pressure ratings support demanding installations.
IO-Link supports parameterisation and diagnostic access. The display assists local service personnel. Electrical protection improves operating reliability. The hygienic surfaces support regular cleaning. Inspection of the process seal and M12 connection supports reliable operation.
