Industrial 18894 Rayotube Temperature Detector

The Industrial 18894 Rayotube Temperature Detector from Leads & Northrup is an industrial-grade sensor whose output is 4.78 mV at 1400°C, enabling direct feed to low-voltage measurement and control circuits. Identified by part number 18894, this Rayotube temperature detector is designed for high-temperature environments where precise, millivolt-level signals are required for monitoring and data collection. The Rayotube family provides a temperature-dependent voltage signal that can be connected to standard instrumentation and signal-conditioning equipment to translate thermal readings into process data. When integrating this detector, ensure the receiving equipment can accurately interpret low-level millivolt outputs and accommodate high-temperature wiring configurations. The explicit value of 4.78 mV at 1400°C defines its electrical response and helps engineers match it to compatible readouts and control loops in industrial applications that demand reliable high-temperature sensing. It is intended for processes that rely on direct millivolt signals rather than powered sensor electronics.
