Any system can come up against adverse dynamic conditions like:
Lightning transients
Utility-line fault clearance transients
Sensor response characteristics
Differences of ground potential
Power supply regulation
Signal/noise ratio, white or black noise
Radio frequency interference (RFI)
System reverberation
Thermal gradients
AC and DC actuator switching
Logic ambiguities
The AGM Signal Conditioners go "beyond the basic" criteria.
Our engineering design was made to augment the basics, and reduce
the degree and frequency of system problems due to uncertain conditions.
They provide a comprehensive signal conversion and processing tool
for the instrumentation engineer's use. Yet, in the field, it is a
simple device for use by the process control operator.
AGM's Signal Conditioning
design considerations include:
System Noise and Interference:
Wide deadband to rectify equipment operation
causing system "bumps".
Time delay to rectify pneumatic or hydraulic
reverberation.
Response time to rectify ambient noise and erratic
sensor signals.
Condensation and Humidity:
Circuitry is potted in high vacuum, degassed,
chemically inert RTV rubber that precludes chemical and bacterial
degeneration causing circuit failure.
Ground Loops:
Optical isolation of module I/O/Power to virtually
eliminate ground loop problems.
Loss of Signal:
Automatic switching in all devices to accommodate
lost of live-zero inputs signals.
Frequency Data:
Digital filters for narrow frequency band signals
in a electrically noisy environment.
Unusual Interface Requirements:
The AGM Lab calibrates extremely narrow analog
spans with high offsets at no charge. Calibration standards are
traceable to the National Institute of Standards and Technology.
