  • Page 12: Product Description

    E2658-PID Rev 12.03.2021 Product description E2658 is a series of flameproof gas detectors-transmitters intended for operation in safe zones and ATEX Zones 2 and 22. E2658 series devices are based on PluraSens® multifunctional platform and provide all its features. The instruments utilize gas sensors of various types with excellent repeatability, stability, and long lifetime.

  • Page 13: Pid (Photoionization Detector) Technology

    E2658-PID Rev 12.03.2021 PID (photoionization detector) technology The gas under investigation diffuses into the sensor’s testing cell, equipped with a source of high energy UV light (10.6 eV Krypton lamp) and electrodes. Exposed to UV light, organic molecules decompose to form ions, which are attracted by the electrodes. The measured resulting current is proportional to the VOC concentration.
  • Page 14 E2658-PID Rev 12.03.2021 For personal safety control, the detectors are installed in the breathing zone (at the height of the head of people or animals). The recommended sensor position is vertical, pointing downwards. The device is fixed on the wall using two fixing holes located outside the sealed area of the device (see dimensional drawing).

  • Page 16: Sensor Probe Handling

    E2658-PID Rev 12.03.2021 Sensor probe handling The sensor probes of all types are equipped with a hydrophobic microporous PTFE filter to protect the sensor from dust, dirt, and water drops. The filter should be replaced if it gets strongly contaminated. To replace the PTFE filter, unscrew the sensor head cap and remove the old filter.

  • Page 17: Electrical Connections

    E2658-PID Rev 12.03.2021 Electrical connections Unscrew four lid screws and detach the lid from the device. Use the M25 cable gland to let in the cables of the power supply and of the external devices. Without turning on the power, plug the power cable, and connect the analog/relay outputs and/or digital interface terminals to the necessary devices according to the relevant connection diagram.
  • Page 18 E2658-PID Rev 12.03.2021 The screwless quick connect spring terminals on the E2658 series devices are suitable for a wide range of wires with cross-section 0,5...1,5 mm . We recommend to strip the wire end by 8...9 mm and use the wire end sleeves. To connect the wire, insert the wire end into the terminal hole.

  • Page 20: Properties Of Voc: Ionization Energy, The Correction Factor

    E2658-PID Rev 12.03.2021 Properties of VOC: ionization energy, the correction factor Sensors used in E2658-PID are calibrated using isobutylene, but the PID is a broadband VOC detector, with a sensitivity that differs for each VOC. If you know what VOC you are measuring, then the table below will allow you to calculate the concentration for your specific VOC.
  • Page 21 E2658-PID Rev 12.03.2021 Occasionally you will be measuring a mixture of VOCs. If the total concentration is within the linear range of your PID, then it is reasonable to assume that the concentrations are additive without interference between the different VOCs. Remember that if you are measuring a combination of VOCs, then the accurate measurement of one of these VOCs will be difficult;...
