Endevco® Model 7264D is a very low mass piezoresistive accelerometer weighing only 1 gram. This accelerometer is designed for crash testing, flutter testing, rough road testing and similar applications that require minimal mass loading and broad frequency response. This accelerometer meets SAEJ211 specifications for impact testing and the SAEJ2570 specification for anthromorphic testing. It is a direct replacement for Endevco Model 7264-2000 and 7264C, in that the location of the center of seismic mass is the same.
Model 7264D utilizes an advanced micromachined sensor which includes integral mechanical stops. This model has a high resonant frequency (>40 000 Hz) and frequency response, which captures more data and avoids spurious noise. The Model 7264D has minimum damping, thereby producing no phase shift over the useful frequency range. With a frequency response extending down to DC (steady state acceleration) this accelerometer is ideal for measuring long duration transient shocks.
This accelerometer has a full bridge circuit with fixed resistors for shunt calibration. Full scale output is 400 mV with 10Vdc excitation. Each unit performs with < 1% transverse sensitivity and ZMO of < ± 25 mV.

The 330400 accelerometer is designed for general-purpose casing acceleration measurements and meets all requirements of API 670. The 330425 is identical except it provides a broader amplitude range (75 g peak) and a sensitivity of 25 mV/g peak. Neither transducer requires an external interface module.
The 330450 HTAS segregates the sensing element from the signal conditioning electronics, with the two permanently connected via a hard-line cable. This allows the sensing head to be mounted on surfaces with temperatures as high as +400°C ( 752°F), while the signal conditioning electronics can be installed in a cooler location.
The 200150 Accelerometer is intended for use only with a compatible Transducer Interface Module (TIM) as part of our Trendmaster® Pro quasi-continuous online condition monitoring system. The accelerometer features a frequency response suitable only for general purpose applications. When machinery with slow rotative speeds will be monitored, use the 200155 and an appropriately configured proTIM instead. For acceleration enveloping applications, use the 200157 and an appropriately configured proTIM.

Wilcoxon Research offers three options for applications in which temperatures are above the normal operating range of industrial accelerometers, greater than 250ºF (120ºC). The FireFET™ series, models 793-6 and 797-6, is designed for continuous operation up to 302ºF (150ºC). These sensors are typically used where extra temperature protection is needed, such as the dryer section of a paper machine.
If an installation is greater than 302ºF, a special type of accelerometer system is necessary. The 376/CC701HT system consists of three parts: sensing accelerometer (376), charge converter (CC701HT) and connecting cable. Using this arrangement, the temperature-sensitive amplifier (charge converter) is removed from the sensor and placed within a separate component outside the intense heat. One end of the charge converter will be connected to the sensor via the supplied cable and the other will be available to connect to analysis or acquisition equipment. As with all "charge mode" sensors, care must be taken to secure the connecting cable when taking data. Movement of this cable may induce false signals (triboloectric effect).

Endevco® Model 7290A Microtron® accelerometer family utilizes unique variable capacitance microsensors. Accelerometers are designed for measurement of relatively low level acceleration in aerospace and automotive environments. Typical applications require measurement of whole body motion immediately after the accelerometer is subjected to a shock motion, and in the presence of severe vibrational inputs.
Gas damping and internal overrange stops enable the anisotropically-etched silicon microsensors to withstand high shock and acceleration loads.
Model 7290A can operate from 9.5 V to 18.0 V and provide a high level, low impedance output. The ±2 volt differential output is dc coupled at a dc bias of approximately 3.6 V. Frequency response is controlled by the near-critically damped sensors. The use of gas damping results in very small thermally-induced changes of frequency response.
