Gas detector DG-PV6R7-Nstd Refrigerants, measurement range on request, IR sensor DG-PV6R7-NSTD

Refrigerant Detection – Reliable Protection and Precise Measurement

The DG-PV6R7-Nstd gas detector is an advanced device designed for continuous monitoring of refrigerant concentration in the air. It utilizes proven infrared (IR) measurement technology, ensuring high accuracy and reliable detection. The device is ideal for industrial applications, ventilation and air conditioning systems, where controlling the concentration of refrigerants is crucial for safety and energy efficiency.

Versatility and Easy Integration

The DG-PV6R7-Nstd detector stands out for its versatility thanks to two signal outputs – current 4-20 mA and voltage 2-10 V. This allows for easy integration with various control and monitoring systems, regardless of the manufacturer. Built-in optical signaling (two LEDs) informs about exceeding the permissible gas concentration limits, as well as the technical condition of the device.

Design and Functionality for Professionals

The device is characterized by a solid construction and splash-proof housing (IP44), which ensures its reliable operation even in harsh industrial conditions. A replaceable sensor module allows for quick and easy calibration and replacement in case of failure or the need to change the measurement range. Detachable terminals facilitate the connection of single- and multi-strand wires without the need for ferrules. Additionally, the detector has a built-in operating time counter and a history of alarm states, which facilitates diagnostics and maintenance. The thermal compensation system minimizes the impact of ambient temperature changes on the measurement result, ensuring accurate readings even in variable conditions. The possibility of mounting an additional mechanical protection AR-1d increases resistance to damage in places exposed to vandalism or accidental impacts.

Specification and Application

The DG-PV6R7-Nstd detector is designed to measure refrigerants R32 or R410A in the range of 0 ÷ 2000 ppm. The device is powered by 24 V DC. Its compact dimensions (110 x 140 x 55 mm) allow for easy mounting in various locations. The device is factory calibrated in accordance with the PN-EN ISO/IEC 17025 standard by the accredited laboratory GAZEX (PCA No. AP150), which guarantees its accuracy and measurement reliability. It should be remembered that DG/PV detectors are not intended for use in areas hazardous due to the explosion of gases, vapors or dusts and are not compatible with MDP, MDA or MDD modules.
