Pentair Raychem RTD4AL Temperature Sensor

The RTD4AL Temperature Sensor from Raychem (now part of nVent) is a three-wire platinum RTD temperature sensor designed for precise temperature measurement in control and monitoring systems. It uses a platinum resistance sensing element and is intended to interface with Raychem monitoring and control equipment to deliver accurate readings in industrial environments. The sensor covers a broad temperature range from -100 to 900°F (-73 to 482°C), enabling reliable operation across many process temperatures. With its three-wire configuration, the RTD4AL helps compensate lead resistance to preserve accuracy on longer wiring runs, making it suitable for automation, heating systems, and process control loops that demand tight temperature control. This model is typically deployed as a standalone sensor assembly and can be mounted using pipe-strap arrangements in field installations. Expect precise temperature sensing with typical accuracy around ±1°F, contributing to stable process control and reliable system performance.
