—— Product Information ——

The CA306 144-306-000-321 series of high temperature accelerometers has been designed specifically for gas turbine applications.
The accelerometers feature a rugged design with hermetically sealed connectors.An integral mineral insulated (MI) cable with stainless steel overbraid ensures signal integrity even in the most hostile environments.The differential output signal minimizes noise pick-up due to electrical ground potentials.A version with side connector is available when an integral cable is not required.
