Gas detector DG-PV9E5 oxygen, 25% v/v, electrochemical sensor, 5-year lifespan RoHS

Gas detectors – reliable oxygen measurement in your installation

DG/PV series measurement detectors, such as the DG-PV9E5 model, are designed for continuous monitoring of gas concentrations in industrial and enclosed spaces. This device, equipped with an electrochemical oxygen sensor, allows for precise measurement of oxygen content in the range of 0-25% by volume. Its main task is to ensure safety by early detection of dangerous gas concentrations, which is crucial for both installers responsible for the proper functioning of gas detection systems and end-users who may be exposed to hazards related to incorrect oxygen content.

Functionality and application

The DG-PV9E5 detector offers versatile integration possibilities with various gas detection systems thanks to two signal outputs: 4-20mA current (active) and 2-10V voltage. This makes the device compatible with central units from many manufacturers. Built-in optical signaling (two LEDs) informs about exceeding the measurement range or a failure. Additionally, the detector has a working time counter function and a history of failure states, which facilitates diagnostics and maintenance. Thermal compensation circuit ensures measurement accuracy even under changing environmental conditions.

The device finds application in a wide range of industrial facilities, such as:

• Production halls
• Laboratories
• Boiler rooms
• Warehouses
• Ventilation and air conditioning systems
• Medical installations (where control of oxygen concentration is critical)

Construction and characteristic features

The DG-PV9E5 detector is characterized by a solid construction and easy installation. Replaceable gas sensor allows for quick and economical replacement of the measuring element after its service life (5 years). Splash-proof housing (IP44) protects the device from moisture and dust. Additionally, the possibility of equipping the detector with a mechanical guard AR-1d increases its resistance to mechanical damage, which is particularly important in places exposed to vandalism or accidental impacts. Removable terminals facilitate connection of single- and multi-core wires without the need for ferrules. The detector has been calibrated in its own GAZEX Calibration Laboratory operating in accordance with the PN-EN ISO/IEC 17025 standard (PCA accreditation No. AP150), which guarantees high accuracy and reliability of measurements. Supply voltage is 24V=.
