Baumer RTD Head‑Mounted Temperature Transmitter — Product Description

Baumer head‑mounted temperature transmitters are compact industrial transmitters designed to be integrated directly with an RTD (Resistance Temperature Detector) sensor, typically Pt100, and mounted at the sensor head or thermowell. These transmitters convert the sensor’s resistance signal into a standardized 4–20 mA analog output (with optional HART communication on advanced models), enabling accurate, reliable temperature measurement and transmission to PLCs, DCS, data loggers or controllers.

Baumer’s head‑mounted transmitters are built for field‑ready usage — compact in DIN form B housings, suitable for installation on industrial RTD probes or part of hygienic sensors (like CombiTemp series). They support 2‑, 3‑ or 4‑wire RTD configurations, offer high accuracy and fast response, and are engineered to perform in harsh, humid or vibration‑prone environments.

🔍 Key Features

✔ RTD Input Support: Direct Pt100 (and similar RTD) sensor connection with 2‑, 3‑ or 4‑wire.
✔ Standard Output: 4–20 mA two‑wire analog current loop output for easy integration into automation systems.
✔ High Accuracy: Very accurate temperature transmission (typically better than ±0.1 °C for Pt100).
✔ Fast Sampling & Response: Quick response times suitable for control loops and process monitoring.
✔ Galvanic Isolation & Configurability: Some universal transmitters (FlexTop series) offer galvanic isolation, HART communication, configurable linearization, and compensation functions.
✔ Compact, Head‑Mounted Design: Fits inside sensor head housings or directly on probe heads for minimal signal loss and compact installation.
✔ Suitable for Harsh Environments: Silicone‑embedded or rugged housings resist humidity and vibration.

🏭 Typical Applications

• Process Temperature Measurement in chemical, petrochemical, water treatment and HVAC systems.
• Food & Beverage / Pharmaceutical where hygienic or compact head installation is required.
• General Process Control and automation loops requiring accurate temperature feedback.
• OEM Instrumentation & Machine Sensors where space‑efficient sensing solutions are needed.

 Summary of Benefits

✔ Improved Signal Integrity: Transmitter mounted near the RTD sensor reduces wiring influence and electromagnetic noise.
✔ Easy Integration: Standard 4–20 mA output simplifies connection to PLC/DCS and SCADA systems.
✔ Compact & Robust: Head‑mounted design saves panel space and withstands industrial environments.
✔ Flexible Configuration: Many FlexTop series units support HART® and advanced setup for linearization or damping.
