PQN Series PQN-3533 Hexane gas detector is designed to detect Hexane in the industrial areas.

With ATEX / IECEx, SIL2 certifications, EN 60079-29: 1 performance approval, and high ingress protection class, it has proved its suitability for harsh environmental conditions.

The Infrared sensor employed PQN-3533 provides excellent output in the 0-100%LEL range.

Connectivity
• Sensor: Pellistor in PQN provides accurate and reliable results.
• Modbus: It is easy to integrate PQN detectors into SCADA systems easily 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: PQ-3R+ relay module integrated PQN Series detectors can manage other equipment or 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: 1/2''NPT - 3/4''NPT - 3xM20 cable entries
• Remote Control: Detector status can be monitored 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.
• Protection: Sunshield and waterproof caps are available for use in extreme conditions.
