Regular transducer calibration is an essential requirement for maintaining the accuracy, reliability and repeatability of the results obtained from a measurement system. m+p international’s m+p SensCal program provides a quick and simple process for calibrating accelerometers (piezo-electric with charge output or IEPE, piezo-resistive, capacitive) in your laboratory, as well as velocity or displacement transducers.

Quick Calibration in Your Lab

We offer the m+p SensCal program as an add-on to a wider m+p vibration test system for checking its transducers without any additional acquisition hardware; or it can be utilized as a standalone calibration system.

m+p SensCal uses a reference accelerometer and shaker system to measure the sensitivity of the sensor-under-test (SUT). The following calibration methods are supported:

  • Calibration with fixed sine frequencies: You specify a set of discrete sine frequencies. These are driven step by step and the transducer will be calibrated for exactly the frequencies required.
  • Calibration using random signals: The transducer will be calibrated over a specific frequency range using a random excitation signal. As the entire frequency range is excited at once, the procedure is very effective.
  • Test run via a sine sweep over standard or user-defined frequency and acceleration ranges.

A complete m+p SensCal system consists of:

  • shaker
  • reference accelerometer
  • m+p international measurement front-end (m+p VibPilot, m+p VibRunner, m+p VibMobile)
  • m+p VibControl (ver. 2.13+) vibration control software with sine and/or random excitation and m+p SensCal

Simply mount the SUT on your shaker and start the short calibration procedure. m+p SensCal is easy to operate within m+p VibControl. On-screen set-up enables you to select a stored profile which defines the frequency range and acceleration amplitude for the test.

Detailed Calibration Certificate for Later Reference

Calibration certificate with your company logo

At the conclusion of the test, comprehensive calibration data can be displayed including graphs showing the deviation of amplitude and phase response of the SUT from that of the reference accelerometer. m+p SensCal creates a detailed calibration certificate with company logo as PDF. It shows, among other things, the sensitivity and the transmissibility with phase information.
