Prosense P Series Gas Detector

Enquiry Item

Prosense ATEX, IECEx certified "P" Series fixed gas detectors are designed and developed according to the demanding conditions found in industrial plants in order to carry out continuous measurement of toxic, explosive and oxygen gases in the air.



 Wide Range Sensors: Pellistor, Electrochemical, Infrared, Semiconductor employed P provides excellent output for the target gas.

 Modbus: P can be integrated to 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: P-3R+ relay module integrated P Series detectors can manage other equipments or link 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 monitored Prosense Gas Monitoring software remotely.
