BEKA ba328c Externally Powered Rate Totaliser

The BEKA BA338C-BL-P externally powered rate totaliser is a panel‑mount instrument that simultaneously displays rate and total from pulse inputs, designed for use with flow meters in hazardous environments. It accepts a broad range of pulse sources—magnetic pickup, switch contact, proximity detector, open‑collector or voltage pulses—and can be configured to show either the sum or the difference of two inputs on separate rate and total displays. The device is intrinsically safe, with BEKA offering variants certified for Ex e, Ex n, Ex p or Ex t panel enclosures and, for certain configurations, Ex nA/Ex tc for Zone 2 or 22 without barriers. The BA338C family provides a lineariser for maximum accuracy, a synchronous retransmitted isolated pulse output, and optional isolated alarms or a 4–20 mA output to integrate with automation systems. The model is packaged in a robust 144 × 72 DIN enclosure with an IP65 front panel, and the suffix BL-P denotes a backlit version for easier reading in challenging lighting. BEKA backs these externally powered rate totalisers with a three‑year guarantee, reflecting confidence in long‑term reliability for industrial process monitoring and control applications.
