This fourth-generation intrinsically safe 4/20mA loop powered indicator has high-contrast 4-digit, 34mm-high displays with a very wide viewing angle. Operating over an extended temperature range, it contains many standard features previously only available as options. Extensive thermal and vibration testing provides maximum reliability.
No additional charge is made for factory calibration or for scale and tag marking; however, the indicators can easily be recalibrated on-site.
Supported by a three-year guarantee.
We are an authorized BEKA distributor shipping to locations in the United States.
What Is a Loop Powered Indicator?
A loop powered indicator is an instrument used in industrial settings to display vital process parameters, such as temperature, pressure, or flow rate, directly from a sensor. These devices are called “loop powered” because they derive their operating power from the current in a 4-20mA control loop, essentially eliminating the need for an external power source. This feature simplifies installation and enhances reliability, especially in remote or hard-to-access locations.
In environments where the presence of flammable gas, vapor, or dust creates a risk of explosion, loop powered indicators must be intrinsically safe. Being “intrinsically safe” means the device is designed to not store enough energy to cause an explosion, making it safe for use in hazardous areas. This is crucial for applications like storage tank indication in chemical processing, fueling stations, or any place where a normal electrical spark could become a source of ignition.
The BEKA BA304G-SS
The BEKA BA304G-SS Intrinsically Safe Loop Powered Digital Indicator is a superior choice for various industrial environments, including those that are potentially hazardous. It’s specifically designed to operate safely within hazardous locations by preventing any risk of ignition in explosive atmospheres.
One of the key features of the BEKA BA304G-SS is its wide temperature range, which ensures reliable operation in abnormal conditions, from freezing temperatures to the heat of industrial processes. This makes it highly versatile, as it is suitable even for outdoor installations or environments with significant temperature variations.
The device’s intrinsic safety is another important feature, allowing it to be used in areas where traditional equipment might pose a risk. As intrinsically safe equipment, the BA304G-SS is engineered to prevent causing a spark or reaching temperatures that could easily ignite combustible dust or gas in the area. This is especially important in sectors such as chemical processing, where the accurate and safe measurement of process variables is critical.
Furthermore, the BA304G-SS’s reliability makes it an ideal choice for a wide range of applications, from monitoring the temperature of chemicals in process tanks to indicating water levels in treatment plants, while ensuring safety in these kinds of potentially explosive environments. Its ability to operate without external power reduces installation costs and complexity. This very useful device is certified to multiple international standards, including IEC 60079.
