Endress+Hauser DTT35-A1A111DB2BAB iTHERM TS1 modular temperature assembly. Pt100 RTD, 4-20mA HART transmitter, G1/2" PN40 process connection, 100mm immersion, IP67.
Product Overview
The Endress+Hauser DTT35-A1A111DB2BAB is a modular industrial temperature assembly from the iTHERM TS1 (DTT35) series, combining a Pt100 RTD sensor with an integral 4-20mA HART temperature transmitter in a form B terminal head. It features a G1/2" PN40 process connection, 100 mm immersion length, and is designed for direct installation in pipes or tanks for accurate process temperature monitoring in chemical, power, and general industries.

Key Features
All-in-One Assembly: Pre-assembled sensor, thermowell, and head transmitter reduce installation time and potential leak points vs. separate components.
HART Smart Communication: Enables remote configuration, trimming, and sensor diagnostics via the 4-20mA loop — no need to remove the head cover.
Modular Flexibility: TS1 platform allows field replacement of the insert (sensor + transmitter) without removing the thermowell from the process.
High Pressure Rating: PN40 (or higher with weld-in thermowell) suitable for process, utility, and skid-mounted applications.
Applications
Chemical & Petrochemical: Reactor and line temperature monitoring in process plants.
Power & Energy: Feedwater, condensate, and lube oil temperature in turbine/boiler auxiliaries.
HVAC & Utilities: Hot/chilled water temperature in building management systems.
Skid & OEM Equipment: Compact temperature feedback for package units (heat exchangers, CIP skids).
Note: The exact immersion length, thermowell style (straight/tapered), lagging extension, and head material are defined by the complete order code suffix. The model shown represents a typical G1/2" PN40, 100mm U, Pt100 + HART transmitter configuration commonly quoted as DTT35-A1A111DB2BAB.
