Excellent quality, made in Germany
The newest member of the Leitenberger Smart Pressure Gate (SPG) product family, the Smart Pressure Gate FC/CC – 4..20mA – CO2 (Part Number: SPG 901_003), an intelligent pressure control unit, specifically developed for CO₂ (R744) refrigeration systems with the highest demands. This modern device with digital communication enables precise regulation even at extremely high operating pressures, making it an ideal choice for sustainable and high-performance refrigeration solutions.
This device serves to replace traditional mechanical high-pressure and low-pressure manometers, featuring integrated digital signal transmission and advanced communication capabilities.
The Smart Pressure Gate 901_003 offers a number of functions that optimize the operation and monitoring of CO₂ refrigeration systems:
Extreme Pressure Rating: Specifically designed to handle the extreme operating pressure ratios of subcritical and transcritical CO₂ (R744) systems.
Mechanical Replacement: Effectively and precisely replaces traditional mechanical high-pressure (HP) and low-pressure (LP) pressure gauges, simplifying the system.
High Measurement Accuracy: The pressure sensor ensures extremely accurate measurement, with only 0.5 % FSS (Full Scale Span) measurement accuracy, guaranteeing optimal system operation.
Standardized Signal Transmission: The pressure values are also available via an analog output with a 4…20 mA signal, which allows for simple integration into existing control systems.
Standard Connections: The device features standardized process connections, which facilitates the subsequent installation (retrofitting) into existing cooling units.
Compact Design: The compact design provides flexible installation options.
