Triaxial accelerometers are designed with three orthogonal sensing elements to enable simultaneous multi-axis measurements (x-, y-, and z-axis). Smaller units minimize mass loading effects and permit installation into confined areas. A unit with a tapped hole in its base may be secured with a screw passing through the object under test to aid in axis alignment, or may be stud-mounted to a separate adhesive mounting base.
These units typically feature a 4-pin electrical connector (for a single cable hook-up) or an integral 4-conductor cable. Types include High Temperature, Miniature, General Purpose, Modal Array, Shock, Seat Pad, or Filtered accelerometers. See accessories for additional mounting equipment or calibration notes for information on calibration. Contact us for detailed selection assistance, or for unique requirements not shown.
Lightweight ceramic shear design, titanium cased hermetically sealed units that minimize effects of mass loading. Some units available with TEDS (Transducer Electronic Data Sheet) and high temperature options.

Series 350 ICP® mechanically isolated, electrically filtered pyroshock accelerometers are designed to withstand and measure extreme high-level, short-duration transient accelerations. These units are ideal for measuring harsh pyroshock events such as found in metal-to-metal tests, impacts and armor testing, explosive studies, pile driver monitoring, and simulated pyroshock events. High-g shock calibration is included with rental of 350 Series units.

Case Isolated AccelerometersCase isolated accelerometers ensure measurement accuracy in the presence of electrical noise sources, such as EMI and ground loops. They utilize ceramic sensing elements in a shear arrangement, offering high output and low noise for excellent signal to noise ratio. Their case-isolated design with titanium housing provides ruggedness and much improved longevity over use of non-isolated accelerometers with insulated coatings or polyimide tape.

Calibration data is provided electronically (on CD or USB memory stick) or as printed copies, depending on quantity rented and end-user preference.
The Modal Shop has internal calibration intervals set for most test products at 1 year. ANSI/ISO/IEC 17025:2000 makes clear that it is the responsibility of the end-user organization (in this case, the renter) to determine the appropriate calibration interval under the requirements of its own quality system. Per this, calibration certificates of rented equipment have "calibrated on" dates, but blank "calibration due" dates. Rentals ship with a customer specific expected return date in mind – if equipment is expected out for 5 months, the last calibration date will be within the past 7 months. Calibration to additional standards (e.g. Z540 or specific FAA requirements) are possible, but there may be an additional charge.
The Modal Shop's Scope of Accreditation can be found here. An example of a calibration certificate can be found here. Please contact us with questions or if a different calibration will be needed for your rental sensors.
The TEDS option is available on several rental transducers. TEDS stands for Transducer Electronic Data Sheet and provides memory within a sensor with manufacturer name, sensor type, model number, serial number and calibration data. It is an approved IEEE standard (1451.4), and many data acquisition manufacturers include the ability to read TEDS sensors. Not sure if your DAQ has TEDS capability? No problem; TEDS sensors can be used alongside non-TEDS sensors with no issues; the TEDS memory is bypassed. Want more information? See our TEDS FAQ.
