NOTES
1. Low-end response of the transducer is a function of its
associated electronics.
2. Short duration shock pulses, such as those generated by metal-
to-metal impacts, may excite transducer resonance and cause
linearity errors. Send for TP290 for more details.
3. Maintain high levels of precision and accuracy using Endevco's
factory calibration services. Call Endevco’s inside sales force at
800-982-6732 for recommended intervals, pricing and turn-
around time for these services as well as for quotations on our
standard products.
Continued product improvement necessitates that Endevco reserve the right to modify these specifications without notice. Endevco maintains a program of
constant surveillance over all products to ensure a high level of reliability. This program includes attention to reliability factors during product design, the support of
stringent Quality Control requirements, and compulsory corrective action procedures. These measures, together with conservative specifications have made the
name Endevco synonymous with reliability.
