Gas detector DG-P4E/MR-Nstd ammonia, measurement range on request, electrochemical sensor DG-P4E/MR-NSTD

Gas detectors – reliable protection and control

The DG-P4E/MR-Nstd gas detector is an advanced device designed for continuous monitoring of ammonia presence in rooms. It utilizes an electrochemical sensor, providing a precise measurement of gas concentration in the range of 0-1000 ppm. The detector is a key element of gas detection systems, offering reliable warning in case of exceeding permissible norms. Its versatility makes it applicable in industrial plants, logistics centers, and public facilities.

Functionality and communication

The DG-P4E/MR-Nstd device is not only detection but also the possibility of integration with surveillance systems. Communication is via an RS-485 port with the MODBUS RTU protocol, enabling data transmission to a central control module. Two built-in relays with NO/NC contacts allow direct control of alarm devices or ventilation systems. Additionally, the detector has a built-in optical signaling system, informing about exceeding the alarm thresholds of ammonia concentration.

Construction and characteristics

The detector has been designed with ease of installation and maintenance in mind. A replaceable sensor module (MS-P4E/N) allows for quick replacement of a damaged sensor or adaptation of the device to other measurement needs. Compact dimensions (110 x 140 x 55 mm) and two cable glands facilitate mounting and connection to existing infrastructure. A built-in microprocessor ensures stable and reliable operation of the device, and a thermal compensation circuit minimizes the impact of temperature changes on measurement accuracy. The detector also has a history of alarm states, which facilitates analysis of events and identification of potential problems. 24V= power supply ensures compatibility with commonly used power sources.
