High Temperature Accelerometers

Charge Output Accelerometers

Charge output accelerometers directly output an electrostatic charge signal proportional to acceleration. These sensors do not contain built in signal conditioning electronics. External signal conditioning is required to interface their generated measurement signals to most readout or recording instruments. The sensors’ charge output signals can be conditioned with either a laboratory-style, adjustable charge amplifier or an in-line fixed charge converter, such as PCB's 422E series, rented seperately.

PCB Piezotronics manufactures several sensors with Inconel housings that are rated to higher temperatures: some to 1200°F / 649°C. Generally, cabling for these sensors are hardline and difficult to manage for short term testing. At this time, the TMS Rental Program only offers items listed on this page.

^*Resolution and low frequency response of charge mode accelerometers is dependent on noise floor and discharge time constant characteristics of the signal conditioning and readout devices used. 422E series in-line charge converters allow 357 Series sensors to be powered with ICP conditioning.

422E Series Low Noise In-Line Charge Amplifiers (Converters)

422E Series units are used with pC/g-output charge mode sensor to interface to ICP® power. Output voltage for the 422E0x or 422E1x converters is ±2.5 V pk.  Output voltage for the 422E5x converters is ±5 V pk. temperature range: -65 to +250°F. Use with low noise (003-style) cable to connect from sensor to 422E series 10-32 input. BNC output.

422E3x Series units are used with ultra high temperature pC/g-output charge mode sensor, such as the 357B61, to interface to ICP® power. Output voltage: ±2.5Vpk, temperature range: -65 to +250°F. Use with low noise (003-style) cable to connect from sensor to 422E series 10-32 input. BNC output.

Triaxial ICP® Extended Temperature Sensors

These sensors connect via standard ICP® power, from standalone or built in signal conditioners, to many current analyzers. Adjusted circuitry allows measurement generally to +325°F (163°C); can effect low frequency specification and broadband resolution.

Notes on Calibration
Back to Top

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 calibrations certificate can be found here. Please contact us with questions or if a different calibration will be needed for your rental sensors.
