Klay Instruments 8000-F-N-G Electronic Pressure Transmitter

The Klay Instruments 8000-F-N-G is a compact, electronic pressure transmitter designed for precise measurement in low-pressure applications, particularly suited for industries like pulp and paper, food processing, and pharmaceuticals. This model features a flush diaphragm (indicated by 'F' in the model code), non-adjustable span ('N'), and a general-purpose housing ('G'). It provides a 4-20 mA output signal for reliable integration with control systems, operating on a 13-40 Vdc supply. Key benefits include high accuracy (±0.2% of span), robust stainless steel construction for corrosion resistance, and a wide process temperature range of -20°C to 100°C, making it ideal for hygienic or viscous media environments. Compared to similar transmitters like those from Rosemount or Endress+Hauser, the 8000 series offers cost-effective performance with easy installation and minimal maintenance. Drawbacks may include limited suitability for high-pressure applications (max 0.1 bar in this calibration) and the need for careful handling to avoid diaphragm damage. Applications include level measurement in tanks, pressure monitoring in pipelines, and process control in low-range scenarios. This unit appears used but in good condition, with an attached fitting nut for mounting.
