            H igh output, industrial grade accelerometer
            with integral hardline cable, and available
            in two temperature ratings. Hermetic
            construction is proof against degradation under
            severe operating conditions including high
            pressure fluid immersion. /F version is suitable
            for milli g monitoring with appropriate
            instrumentation.
            High temperature vibration measurement may
            be subject to increased noise level caused by
            insulation resistance drop and high level of pyroelectric
            charge generation, necessitating
            bandwidth limitation. Low level measurement
            threshold is determinated by wide band noise,
            series and common mode electrical interference.
            These can be minimised by choice of
            instrumentation and transducer cabling.
            Construction comprises electrically isolated
            KONIC sensing element and all welded case and
            case/cable seal for maximum measurement
            integrity and reliability. Proof pressure testing
            and elevated temperature burn in is
            recommended where appropriate.
