PQ Series Fixed Gas Detectors

PQ Series Fixed Gas Detectors

PQ Series Fixed Gas Detectors

Prosense "PQ" series fixed gas detectors are designed and developed according to the demanding conditions of the industry in order to carry out continuous measurement of toxic and explosive gases in the air. With its ATEX certification, it has proven its suitability for harsh environmental conditions.

It is able to provide measurement stability, target gas measurement and accuracy thanks to sensors which are suitable for industrial conditions.

It is classified as PQN and PQD to provide the best solution for developing industry conditions and customer demands.

PQD Fixed Gas Detectors

  • PQD fixed gas detectors offer the best solution for LEL and ppm measurements using pellistor, infrared, electrochemical and semiconductor sensors.
  • PQD gas detectors provide the user with instant information on the status and ambient conditions of the targeted gas through the OLED display.
  • User-friendly software allows for easy adjustments.
  • As standard, 4-20mA and RS485 (Modbus RTU) outputs can easily be operated by connecting to Prosense S Series panels or a suitable PLC.
  • With its SH30 Stainless Steel sensor head, it performs best under harsh environmental conditions.
  • It can be used with the optional P-3R relay card and 3 dry contact relay outputs. Alarm 1 and Alarm 2 relays can be set to default LEL or ppm levels. The third dry contact relay output is used for Fault status.
  • PQD gas detectors can be safely used in potentially explosive atmospheres thanks to the ATEX certification and with the IP-65 protection class, which can be used safely in harsh outdoor conditions.
  • With the optional P-IP66, it can also be safe against strong water jets.
