PROSENSE "PQN" Series fixed gas detectors are certified with ATEX/IECEx and SIL2.
Ex-proof Safety
The continuous measurement of toxic and explosive gases is done safely in hazardous areas thanks to the ex-proof housing.
Performance Approval
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
malfunctioning equipment could pose a
potential risk. PQ series has ongoing
process for SIL-2.
Robust and Durable
SS316 stainless steel sensor head
performs perfectly under harsh
environmental conditions with the IP65/
IP66 protection class.
Accurate Readings
Pellistor, Electrochemical, PID, and
Infrared sensors undoubtedly provide an
accurate and sensitive measurement.
Ready to Operate
4-20mA Analog and Modbus RS485 RTU
outputs are provided onboard to operate
properly without any additional setup.
Easy Maintenance
PQN Series detectors allow sensor
replacement with pre-calibrated sensor
head thanks to the Procell technology.
Automatic Calibration
Detector calibration can be done
automatically via preset values recorded
in detector software once calibration
requirements are provided.
Pellistor-Saver Mode
Detectors power off the sensor in high
gas concentration in order to properly secure the operational lifetime of pellistor sensor.
Auto Analog Signal Calibration
and Monitoring
PQN Series detectors continuously check
the analog output signal level to match
the measurement level before promptly
transferred to the panel. PQN Series
adjusts the signal level in case of any
deviation and generates a fault signal
when the adjustment fails.
Zero Suppression
Adjusting, the detector can show a
certain measurement level as 0 (zero) to
avoid unnecessary concerns.
Simple External Equipment Control
Optional relay module enables you to use
it as an independent gas detection
system with two arbitrarily adjustable
concentration alarms and one fault
alarm.
Continuous Self-Test
The detectors check itself continuously to
make sure it operates perfectly and
indicates a fault in case of any failure.
Adjustable Parameters
All parameters can be easily changed
according to the application requirements
or facility standards.
Maintenance via Software
Prosense provides software to maintain
your active system easily and calibrate
the gas detectors properly via computer.
