Zero Suppression Trustworthy Certification Adjus ng, the detector can show a certain measurement level as 0 (zero) to avoid unnecessary concerns. PROSENSE "PQD" Series fixed gas detectors are cer fied with ATEX/IECEx/ UKEX/INMETRO/ECASEx and UL/CSA. Simple External Equipment Control Ex-proof Safety Op onal relay module enables you to use it as an independent gas detec on system with two arbitrarily adjustable concentra on alarms and one fault alarm. The con nuous measurement of toxic and explosive gases is done safely in hazardous areas thanks to the ex‐proof housing. Performance Approval Continuous Self-Test It complies with the measurement performance criteria in accordance with the IEC/EN 60079‐29‐1 standard. Functional Safety Prosense promotes SIL approved products to reduce safety risks associated with increasingly complicated systems as malfunc oning equipment could pose a poten al risk. Prosense PQ Series is cer fied by TUV Rheinland as SIL2/SIL3 func onal safety level. Robust and Durable SS316 stainless steel sensor head performs perfectly under harsh environmental condi ons with the IP65/ IP66 protec on class. Accurate Readings Pellistor, Electrochemical, PID, and Infrared sensors undoubtedly provide an accurate and sensi ve measurement. Ready to Operate 4‐20mA Analog and Modbus RS485 RTU outputs are provided onboard to operate properly without any addi onal setup. Easy Maintenance PQD Series detectors allow sensor replacement with pre‐calibrated sensor head thanks to the Procell technology. The detectors check itself con nuously to make sure it operates perfectly and indicates a fault in case of any failure. Adjustable Parameters OLED Display The OLED screen can be easily read from any angle. SAFELOG Data Logger PQD Series records status up to 250 events. In case of sudden power cut, you can save the data thanks to the cell ba ery. Automatic Calibration Detector calibra on can be done automa cally via preset values recorded in detector so ware once calibra on requirements are provided. All parameters can be easily changed according to the applica on requirements or facility standards. Remote Display Depending on the applica on requirements, the screen can be placed separately. Easy Status Recognition Colored LEDs (green, yellow and red) provide addi onal alarm and status informa on. Prosense provides so ware to maintain your ac ve system easily and calibrate Detector power off the sensor in high gas the gas detectors properly via computer. concentra on in order to properly secure the opera onal life me of pellistor Applications sensor.  Oil&Gas Pellistor-Saver Mode Auto Analog Signal Calibration and Monitoring PQD Series detectors con nuously check the analog output signal level to match the measurement level before promptly transferred to the panel. PQD Series adjusts the signal level in case of any devia on and generates a fault signal when the adjustment fails.  Petrochemical  Onshore/Offshore  Steel‐Metal Industry  Chemical Industry  Process Industry  Gas Distribu on Sta ons  Water Treatment Plants PROSENSE TEKNOLOJI SANAYI LIMITED SIRKETI Cumhuriyet Mah.
