E2608-PID Rev 05.03.2021 Product description E2608 series detectors-transmitters belong to the PluraSens® family of multifunctional measurement instruments. The instruments utilize gas sensors of various types with excellent repeatability, stability, and long lifetime. E2608 series provides two independent analog outputs OUT1 and OUT2, user-selectable to 4-20 mA or 0-10 V.
E2608-PID Rev 05.03.2021 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.
E2608-PID Rev 05.03.2021 Installation guidelines Before proceeding with the installation it is mandatory to read the Safety requirements section and make sure to comply with all listed instructions. Installation standards EN 60079-29-2 and EN 45544-4 are also recommended for further instructions and related information about the installation.
E2608-PID Rev 05.03.2021 Sensor probe handling The wall-mount version of the detector-transmitter is available with a remote probe (see drawing below for dimensions). The remote probe is connected to the main unit with a shielded cable. The default remote probe cable length is 3 m. Wall mount remote probe with fixing clamp (default version), Remote probe with rubber flange and three self-tapping screws (on request) The sensor probes of all types are equipped with a hydrophobic microporous PTFE filter to...
E2608-PID Rev 05.03.2021 Electrical connections Unscrew four lid screws and detach the lid from the device. Use the M16 cable gland to let in cables of the power supply and of the external devices. Attach the power cable to the device without turning it on.
E2608-PID Rev 05.03.2021 Operation Turn on the power. The instrument warm-up time takes ≤1 minute after switching on and the final sensor stabilization time to maximum accuracy takes <5 minutes. The operating status is indicated by the LED on the PCB of the device. The control LED (red) response to different processes is presented in the following table: Mode LED mode...
E2608-PID Rev 05.03.2021 Properties of VOC: ionization energy, the correction factor Sensors used in E2608-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 20
E2608-PID Rev 05.03.2021 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;...
