P-7231 Refrigerant gas detector is designed to detect Refrigerant (Freon) gas in industrial areas. ATEX, IECEx certified P-7231 is ready to use in an explosive atmosphere.
Infrared sensor in P-7231 shows the excellent result in 0-2000ppm.
Connectivity
• Sensor: Uses high-quality semiconductor sensor specially designed to detect Refrigerant (Freon) gas
• Modbus: It is easy to integrate SCADA systems via open-source Modbus RS485(RTU) codes
• Outputs: Different devices can be operated/controlled at the same time thanks to the 4-20mA analog, Modbus RS485, and Relay outputs
• Relay Contacts: P-3R+ relay module integrated P Series detectors can manage other equipment or it can be linked to firefighting panels.
Maintenance and Installation
• Sensor Replacement: Allows sensor replacement with pre-calibrated sensor head to provide easy maintenance.
• Installation: Designed for either wall or ceiling mounting applications
• Entry: 2 x 1/2″ NPT cable entries
• Remote Control: Detector status can be also monitored via Prosense Gas Monitoring software remotely.
Robust and Reliable
• Body: Aluminium die-cast body and SS316 stainless steel sensor head superb performance under harsh environmental conditions with IP65 protection class.
