Description

The Endevco® model 65HTLPF is a miniature IEPE high

temperature (up to 175°C) triaxial accelerometer with 2-pole low-

pass filter. The sensor is designed for use in test and measurement

applications requiring both high temperature operation and

effective attenuation of high-frequency, high-g signals that can

obscure the required low-frequency information and also can cause

saturation of electronics. Additionally, the low-pass filter provides

resonance suppression. The model 65HTLPF is packaged in a 10

mm cube of welded titanium construction. Interface to the model

65HTLPF triaxial accelerometer is made via a side connector

Microtech style 4--pin receptacle. Power to the sensor, in the form

of a constant current, travels through the same pins as the low

impedance output signals.

The model 65HTLPF-10 features a sensitivity of 10 mV/g. The

model number's second suffix indicates the low-pass filter corner

frequency at level - 3dB. Two options are currently available, the

model 65HTLPF-10-02 featuring a corner frequency of 2 kHz and

the 65HTLPF-10-10 featuring a corner frequency of 10 kHz. Other

corner frequencies are available upon request.

This product is fully compliant to the European Union's Low Voltage

Directive, 2006/95/EC and EMC Directive 2004/108/EC and is eligible
