The 44423A is a Data Logger from HP. Data loggers, or data recorders, collect information over time for a variety of purposes. A data logger uses internal memory and sensors to gather and document information on a 24-hour basis. Receive an accurate and comprehensive picture of the environmental conditions you’re monitoring as the device logs this information around the clock. Use data logging to measure temperature, humidity, wind speed, solar radiation, soil moisture levels, road traffic, tank levels, and a number of other elements.
- 20 Channel FET Multiplexer Assembly
- Provides high speed, low level multiplexing
- Maximum signal levels are 12 volts peak between any high, low or guard input and any other guard input, guard common or chassis ground
- The 44423A is Option 030 of the HP 3497A Data Acquisition/Control Unit
The HP 44423A (option 030) assembly is used to multiplex input signals to a DVM in a manner similar to option 010. The 44423A assembly provides high speed, low level multiplexing. Maximum signal levels are 12 volts peak between any high, low or guard input and any other guard input, guard common or chassis ground.
Maximum sequential scanning rate: 4800 readings/s (at 60 Hz) using an HP 3437A Voltmeter and HP Series 200 computer (4000 readings/sat 50 Hz power).
