Sensors
Accelerometers & Cables
Accelerometers should be calibrated on a yearly bases by a calibration lab.
Accelerometers do need replacement when worn. We recommend keeping one to two
spars available at all times. We recommend a 3030B5 made by Dytran. You may also
use any standard 10 mv/g Accelerometer please make sure it has proper specs for the
environment you are going to be putting it into.
The accelerometer cable also needs to be checked regularly for abnormal ware. These
should be replaced yearly to provide best readings. Keeping one to two spars available
at all times is recommended. The stock ones are 10-32 to BNC using a teflon or high
temp jacket.
Thermocouples
Thermocouples (T/C) do breakdown over time. It is recommended to check the
accuracy of your Thermocouple against known T/C. Also make sure to check the
insulation of the T/C for abnormal ware. Any ware that the two separate wires that
make up a T/C touch create a new measurement point. Replacement of the T/C is
advised. Our standard T/C is a 70XTSUC120A made by Watlow. This T/C is a Type T
with non-grounding tip.
