Advanced Installations
This chapter contains information on various advanced installation topics
that may apply to your system. Kinemetrics’ Service Group can provide
additional information on these topics.
CE Compliant Installations
The EpiSensor has not yet been CE certified.
Using EpiSensors with Altus
Instruments
The Altus K2, Mt. Whitney and Etna can all power the EpiSensor in its low-
power configuration. (Low-power amplifier, +/-2.5V single-ended output,
any range.) The K2 and the Mt. Whitney can also power multiple
EpiSensors in the low-power configuration.
The Makalu (formerly known as the Everest) recorder can power
EpiSensors in any configurations and can accept the +/-20V differential
input.
Generally there is no reason to use the low-noise amplifier with standard
Altus instruments, as the noise floor of the sensor in the low-power
configuration is below the digitizer noise floor. There are two exceptions to
this rule:
!
You have an Altus instrument with a gain board and plan to use
either a dual-gain configuration or a high-gain channel. This is
explained below.
!
You have a long cable run, or a high noise environment, and would
like to benefit from the improved common mode rejection of a
differential output.
In these situations you must be sure that the Altus instrument can supply
sufficient power to the EpiSensors.
