Gas detector DG-PV5E-Nstd – reliable monitoring of hydrogen sulfide concentration

The DG-PV5E-Nstd gas detector is a precise tool designed for continuous monitoring of hydrogen sulfide (H₂S) concentration in the air. The device uses an electrochemical sensor, providing accurate and reliable measurements in various industrial conditions. It is an ideal solution for both installers of gas detection systems and end-users who need effective protection against the hazards associated with the presence of this toxic gas.

Functionality and application

The DG-PV5E-Nstd detector is designed to operate in enclosed industrial spaces where there is a risk of dangerous concentrations of hydrogen sulfide. It signals exceeding permissible norms, allowing for a quick response and preventing adverse health effects. Thanks to the 4-20mA and 2-10V analog outputs, the detector is compatible with various control and monitoring systems, including devices from other manufacturers. This makes integration with existing infrastructure simple and effective.

Key features and benefits

• Replaceable sensor: the ability to replace the measuring module allows you to adapt the detector to specific needs and extend its lifespan.
• Two signal outputs: the presence of both a 4-20mA (active) current output and a 2-10V voltage output provides flexibility in connecting to various control systems.
• Built-in diagnostic functions: the detector monitors its own status, signaling exceeding the measurement range, failures, and the approaching calibration date.
• Thermal compensation: the temperature compensation system ensures measurement accuracy even in variable environmental conditions.
• Fast response time: the detector reacts quickly to changes in gas concentration, which is crucial in emergency situations.
• Optical signaling: two LEDs indicate the device status and exceeding the alarm concentration thresholds.
• Splash-proof housing (IP44): provides protection against moisture and dust, allowing installation in harsh industrial conditions.
• Calibration in an accredited laboratory: all detectors are calibrated in the GAZEX Calibration Laboratory, which has PCA accreditation No. AP150 in accordance with PN-EN ISO/IEC 17025, which guarantees high measurement accuracy.

Construction and mounting

The DG-PV5E-Nstd detector has a standard housing designed for stationary mounting. Removable terminals facilitate connection of wires without the need for crimp sleeves. Please note that the device is not intended for use in areas hazardous due to the explosion of gases, vapors or dust. Additional mechanical protection covers (type AR-1d) are available for places exposed to mechanical damage, as well as housings for mounting on ventilation ducts (option DG/w).

Compliance with standards

The device meets the requirements of applicable standards and regulations regarding the safety and reliability of gas detectors. Regular calibration ensures compliance with legal requirements and maintains high measurement accuracy throughout the service life.
