【DPM-911B/912B】

Strain Amplifier with high stability and accuracy, also with high frequency response from DC to 10kHz(913B)

【DPM-913B】

Frequency response from DC to 10kHz
Disconnection can be checked through the entire input system, including cables and connectors.

 

Features

【DPM-911B/912B】

  • Simple operation vastly reduce the working hours
  • Digital switch makes setting easy and the setting value is easy to be seen even during power is off.
  • Sensitivity (measuring range) is set in combination of strain level and output voltage settings.
  • High voltage output of ±10V and high SN ratio are ensured
  • Vertical bar meter is easy to see
  • The high-pass filter cancels the effect of slow changes, such as temperature drift of gages or sensors
  • Sensitivity of TEDS-installed transducer is automatically registered
  • Stable monitor indication saves time in setup and measurement.
  • Sensitivity is automatically set with the actual load calibration function.
  • Checking function on bridge circuit is available
