Product Name: Intrinsically Safe Externally Powered Pulse Input Rate Totaliser

Product Description

The BA344D is an external powered, intrinsically safe, rate totaliser with separate rate and total displays which will operate from a switch contact, pulse, magnetic pick-off or a proximity detector input. Main application of the BA344D is to process the pulse output from a hazardous area flowmeter, and to display the rate of flow and the total flow in the same or different engineering units. The instrument may be used with any flowmeter having a pulse output proportional to flow rate, such as a turbine flowmeter. When fitted with optional alarms, the instrument can perform simple flow batching applications, and an optional pulse output allows a remote counter to be operated. Rotational speed of machinery may also be measured and displayed by the BA334D. The instrument will operate from most intrinsically safe 2-wire proximity detectors and, when fitted with alarms, over and under speed warnings can be generated. Control and programming of the BA334D is performed via four push buttons which are protected from damage and tampering behind a sealed cover. For applications requiring frequent adjustment, the instrument can be supplied with a robust external membrane keypad. All the programme functions are contained in easy to understand menus, which may be protected by a user definable security code. To simplify calibration the rate and total scaling factors employ floating decimal points.
