Endress+Hauser iTHERM ModuLine TM131 (FLEX) is a modular industrial temperature sensor/thermometer assembly designed for demanding and hazardous-area applications. It supports RTD (Pt100) and thermocouple measuring inserts with multiple wiring options, and can be configured with head-mounted transmitters offering 4–20 mA and digital communications (e.g., HART/fieldbus/IO-Link options depending on configuration). The design is highly configurable (terminal head materials, thermowell/protection tube materials, immersion lengths up to 4,500 mm) and offers extensive global Ex approvals and optional features like surge protection, QuickNeck, and robust sensor elements for high-vibration installations.
