34970A Agilent Data Logger

Used
$795.00

The 34970A is a Data Logger from Agilent. 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.

Additional Features:

  • 3-slot mainframe with built-in GPIB and RS232 interfaces
  • 6 1/2-digit (22-bit) internal DMM, scanning up to 250 channels per second
  • 8 switch and control plug-in modules to choose from
  • Built-in signal conditioning measures thermocouples, RTDs and thermistors, AC/DC volts and current; resistance; frequency and period
  • 50k readings of non-volatile memory holds data when power is removed
  • Hi/LO alarm limits on each channel, plus 4 TTL alarm outputs
  • Free BenchLink data logger software to create tests without programming

The Agilent 34970A is easy to use for a-multitude of data logging and monitoring applications, either stand-alone or with a computer. Its-flexible, modular design makes it-scalable from 20 to 120 channels, and lets you add actuator, digital I/O, and analog output channels for simple control. Its small size and ruggedized features make it perfect for portable applications, and its small footprint makes it ideal for cramped benchtop testing. Standard GPIB (IEEE 488) and RS-232 interfaces let you program the instrument if you wish to automate tests.

What’s more, each channel is independently configurable. This means you can configure channel 1 for dcV, channel 2 for a K-type thermocouple, and channels 3 and 13 for a 4-wire RTD measurement, all on the same module, all in a single scan. For custom linear conversions, use the Mx+B scaling function on any channel. You can even display a custom 3-character engineering label like RPM or PSI to identify your measurement units.

Alarms are available on a per-channel basis as well. Enter a high limit, a low limit, or both. The unit compares each reading to its limits and flags any out-of-range measurements. You can assign one of four TTL alarm outputs to any input
channel to trigger external alarm lights, sirens, or send a TTL pulse to your control system, all without a PC connected.

This unit automatically builds-a scan list that includes all configured inputs (even digital inputs from the Agilent 34907A multifunction module) in ascending order by channel number. You can pace scans by setting the unit’s internal timer for automatic scanning at a specific interval, by manually pressing a front-panel button, or by sending a software command or external TTL trigger pulse.
