7.30830.32.00 75
А А ADC printed circuit board, analog/digital converter (terminals 1, 2, 3, 20 and 30)
•
Signal processor protected against overload, for quick and precise processing of flow peaks up to and exceeding
20 m/s or 60 ft/s.
•
Digital signal processor, sequential control and test routines.
•
Patented high-resolution analog/digital converter, digitally controlled and monitored.
•
Input amplifier allowing control of potential of signal line shielding (bootstrap).
•
User parameter and internal calibration values are stored in separate EEPROMs (easily replaceable)
Б Б FSV printed circuit board, field current supply (terminals 7 and 8)
•
Large signal-to-noise ratio owing to low-loss field current supply with high frequencies and high currents.
•
Pulsed direct current which is precisely controlled electronically, for the magnetic coils of the primary head.
•
Operating and calibrating data are stored in an EEPROM so the PCB can be easily replaced without the need for
re-calibration.
В В BDE printed circuit board, motherboard
•
Large illuminated LC display.
•
15 keys for operator control of signal converter.
•
Can be retrofitted with optional operator control by bar magnet.
•
Distribution of general signals such as ImoCom bus, power supply.
Г Г I/O printed circuit board, inputs and outputs
•
Groups, input and outputs are galvanically isolated from each other and from all other circuits.
•
Power supply source for the inactive inputs and outputs.
•
Specific supply source for the inactive inputs and outputs.
•
Specific Krohne circuit KSA 04 for fine quantization of output pulses across a wide dynamic range.
•
Active current output I (e.g. 0/4 – 20 mA) with load control
•
Pulse output P for electronic totalizers, max. 10 Hz.
•
Pulse output A1 for electromechanical totalizers, max. 50 Hz, can also be used as status output A1.
•
Several status outputs A1, A2, D1, D2.
•
Control inputs C1 and C2.
Д Д ImoCom bus plug
Connecting external operating and testing devices, e.g. RS232 adapter and CONFIG software for operator control of
signal converter by MS-DOS PC or laptop.
Е Е Slots for plug-in modules, for upgrading or converting the signal converter
