Pyromation 401-85U-3115F RTD Transmitter

The Pyromation 401-85U-3115F is a compact, loop-powered RTD transmitter designed for accurate temperature measurement and signal conversion in industrial applications. This model features a pre-calibrated range of 30 to 230°F, making it ideal for processes requiring precise monitoring in moderate temperature environments, such as food processing, HVAC systems, pharmaceuticals, and general manufacturing. It converts RTD input (typically Pt100) to a standard 4-20 mA output, ensuring compatibility with PLCs, DCS, and other control systems. Key benefits include high accuracy (±0.1% of span), excellent stability, and easy installation in sensor heads or enclosures. Compared to similar products like those from Omega or Rosemount, the Pyromation 401 series offers superior customization options through model decoding, robust construction for harsh environments, and cost-effectiveness without sacrificing reliability. Drawbacks may include limited range flexibility post-calibration and the need for external power looping. This unit appears new, sealed in original packaging, with no visible wear, and includes a faceplate label confirming the model, range, and manufacturer details. No parent/child assets are evident from images. For detailed specs, refer to Pyromation's official datasheet (available at https://www.pyromation.com/Downloads/Data/Transmitters.pdf).
