Seitron Cool Guardian R407A: Fixed refrigerant gas transmitter with semiconductor sensor for R407A - SREN21B

The Cool Guardian Refrigerant Gas Transmitter from the SR series is an advanced solution designed to precisely monitor refrigerant gases in industrial applications, making installation, management, and maintenance operations even more efficient and safe. Thanks to its innovative technology and versatile features, the Cool Guardian is ideal for environments where monitoring the presence of refrigerant gases like R407C and ensuring system safety is essential. In this article, we will explore in detail the technical characteristics, benefits, and applications of this product, emphasizing how it can simplify refrigeration system management.

Main Features of the Cool Guardian Refrigerant Gas Transmitter

The Cool Guardian SR-Series transmitter is designed to monitor refrigerant gases such as R407C, a mixture primarily used in air conditioning and refrigeration systems. With an operating temperature range from -40°C to 50°C, this device is perfect for a wide range of operational environments, ensuring reliability even in harsh environmental conditions. The transmitter is designed with an IP65 protection rating, making it dust and water splash resistant, guaranteeing optimal performance even in industrial environments.

One of the most advanced features of the Cool Guardian is its ability to manage three configurable relay outputs, which allow for controlling external loads such as audible and visual alarms, ventilation systems, and other safety applications. The relay outputs offer unique flexibility, adapting to the specific needs of the system.

Furthermore, the transmitter is equipped with a configurable analog output in various modes: 4-20mA, 0-5V, 0-10V, 1-5V, and 2-10V. The ability to configure the analog output via a mobile app allows users to easily customize settings to suit specific monitoring needs, thereby improving the device's versatility and ease of use.

Advanced Connectivity: Modbus® and RS485

Another significant advantage of the Cool Guardian transmitter is its Modbus® output via RS485, which uses the Modbus® RTU protocol. This functionality allows connecting up to 32 devices in a centralized monitoring system, making the Cool Guardian ideal for large industrial applications. Modbus® communication offers simpler management and more effective remote diagnostics, enabling operators to monitor safety parameters in real time and detect any anomalies or gas leaks.
