Description
Easy and Safe Use
• OLED Display: 128×64 large, bright, and clear display indicates gas level, detector status and it can be seen in dark locations and different angles easily
• Non-Intrusive Calibration: Zero and Span calibration can be done by a single operator using magnetic keys without opening the lid in the hazardous area.
• Logging: Stores all alarm, fault, and maintenance events up to 250logs to provide a history of the detector. Also, it protects the data thanks to the battery itself
• Monitoring: Gas concentration trends for the last 8 hours can be monitored on the OLED screen as it is recording the measurement data
• Remote Control: PQ offers up to 15meters remote control option for applications that sensor and transmitter specifically require separate locations.
• Magnetic Control: Many settings can be adjusted using a magnetic key.
Easy Maintenance and Simple Installation
• Checking: Relay contacts can be activated or deactivated easily through a user-friendly PQD menu
• Simulation: 4-20mA analog output can be simulated in different values for the test purposes, even if there is no target gas in the environment.
• Analog Values: Fault, Warm-up, Calibration, Inhibit, and Overrange values are adjustable.
• Address: Modbus addresses can be set on the detector menu. No need for onboard addressing switches anymore.
• Calibration: Reminds the user when calibration is due to ensure that sensors remain operational and accurate at all times
• Relays: Alarm levels and related parameters can be fully adjustable via detector software.
• Sensor Replacement: Allows sensor replacement with a pre-calibrated sensor head to provide easy maintenance.
• Modbus: PQ can be integrated into SCADA systems easily via open source Modbus RS-485 (RTU) codes.
Reliability
• Bump Test: The status of the detector can be checked periodically. Ensure that the sensors will respond to their target gas and that the alarms will function
• Calibration Due Warning: Reminds the user by giving a Fault when calibration is due
• Wide Range Sensors: High-quality PID, Pellistor, Electrochemical, Infrared, Semiconductor employed PQ provides excellent output for the target gas.
