In addition to these calibration systems, TMS also provides traceable, quick turnaround calibration services!

The Accelerometer Calibration Workstation Model 9155C features accurate back-to-back comparison calibrations of ICP® (IEPE) and charge mode piezoelectric accelerometers in accordance with ISO 5347-3. Benefits of the Model 9155C form in two areas: conformance to existing standards and automation of the calibration task.

Produce NIST traceable vibration sensor calibration reports that comply with ISO 17025 / A2LA requirements using the TMS Model K9100C Portable Vibration Calibration System. The K9100C is designed to calibrate most vibration sensors in a bandwidth from 10 Hz to 10 kHz using an Agilent 34401A digital multimeter to measure the signal from the unit under test. The K9100C allows for automated calibration certificate generation by entering data into the supplied Visual Basic macro for Microsoft Excel.

In contrast to more elaborate laboratory style systems, the Model K9100C is portable, making it ideal for testing in the field or at a customer's site. The self-contained 9100C calibrator unit is equipped with it's own rechargeable power source, which makes the system an excellent choice for any fieldwork where power is not available. An external charger/power supply provides charging and operational current when used in the lab.

The Portable Vibration Calibration System allows the user maximum flexibility when adjusting frequency ranges (10 Hz - 10 kHz) and amplitude settings (Acceleration, Velocity, Displacement). The LCD readout of the shaker amplitude and frequency can either be displayed in English or Metric units. To ensure the accuracy and reliability of the test readings, an integrated NIST traceable reference accelerometer is included in the 9100C. Due to a unique suspension, the Model 9100C can support sensors that weigh up to 500 grams without the aid of an external support mechanism.

In addition to the Model 9100C, the K9100C includes an Agilent 34401A DMM, appropriate cabling, and the MS Excel Visual Basic macro for automated report generation. The only items required for calibration are user supplied signal conditioning and sensors.

• Generates ISO 17025 and A2LA compliant calibration certificates.
• Perform frequency and amplitude sweeps with adjustable settings.
• Acquire NIST traceable measurements with reliable instruments from TMS and Agilent.
• Displays information for acceleration, velocity, and displacement in either English or Metric   units.

Eight high-accuracy reference accelerometers define the rigid-body motion of the platform, allowing calculation of the acceleration at each test point. The system calibrates all the accelerometers at a single frequency (or across the 500 Hz bandwidth) in just minutes. This calibration system is ideal for modal or vibration test laboratories with large numbers of accelerometers. By operating through the complete measurement channel, the array calibrator also can serve as an end-to-end system check before large tests. The system can be incorporated into most commercial data acquisition systems (such as LMS CADA-X, HP 3566 or HP E1432A), or can operate as a stand alone system.

• Calibrates up to 64 accelerometers simultaneously.
• Provides both magnitude and phase information from 1 Hz to 500 Hz.
• Adapts to existing large channel data acquisition systems.
• Creates an efficient and cost saving calibration management system for large channel-count   testing.
• Uses eight high sensitivity reference accelerometers to calculate the global rigid body motion
  of the calibration platform.
• Available in 32 and 64 channel platforms.

The 996x Series Gravimetric Calibration System provides for calibration of accelerometers, force sensors, and impact hammers over the low to mid frequency range. For measuring a single value sensitivity, accelerometers and load cells may be "drop" calibrated without a reference sensor, using Earth's gravity instead. Impact hammers are ratio calibrated using a known pendulous mass, a calibrated accelerometer, and Newton's Second Law. The Gravimetric Calibrator is structured with an adjustable frame, vertical and pendulous suspensions, and calibrated test masses. The system is an economical, educational and versatile tool - an important accessory in any structural test laboratory.

• Saves time and improves efficiency by automating calibration routine.
• Calibrates both accelerometers and force transducers.
• Converts existing PC into desktop calibration acquisition system.
• Improves accuracy and consistency by implementing exponential curve fit to free-fall
  calibration data.
• Calibration data allows transducer trending for better instrumentation management.

The Precision Acoustic Calibration Workstation Model 9350C is an accurate, turnkey, automated PC-based system that features cost-effective calibration of ¼", ½" and 1" microphone cartridges (open-circuit sensitivity), microphone cartridges with preamplifiers (closed-circuit sensitivity) and microphone Frequency Response Function.

In addition, the system provides for conformance testing of microphone preamplifiers and acoustic calibrators: pistonphones as well as speaker phone based calibrators.

Under complete software control, the 9350C operates in four modes:

• Microphone Cartridge Calibration
• Microphone & Preamplifier Calibration
• Preamplifier Conformance Test
• Source Calibration

A calibration certificate may be generated, or the results may be saved in the database.
