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.

System Noise and Interference:

	Wide dead band 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.

"Wireless TransCeiver (WTC)"

"Telephone Lines are for the Birds"

As leased dedicated phone lines are becoming more difficult to acquire, AGM customers are switching to wireless data communications using AGM's Data Handlers (DH) and Spread Spectrum Radios (SSR).

"Beep Alert"

The Data Handler, when combined with your existing  pager system, provides a convenient, low cost way to detect and broadcast remote site alarms such as a pump failure or unauthorized intrusion.

"AWT"

Erratic flow signals can result in unnecessary wear and tear on chemical feed equipment.

Use the Data Handler application, "Average with Time", to smooth the signal.
