        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What signal conditioner is recommended to process the raw output of the Vibro-Meter TQ402 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10 sensor?
        The Vibro-Meter TQ402 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10 is highly optimized to work with the modern IQS900 signal conditioner. It can also be integrated into legacy loops running older IQS450 conditioners, provided the electronic calibration curves are selected to match a 10-meter total system length.
        Can we cut the 1.0m integral cable of the Vibro-Meter TQ402 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10 if it is too long for our junction box connection?
        No, you must never cut or shorten the cable of the Vibro-Meter TQ402 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10. The electrical capacitance and impedance of the 1.0m integral cable plus the 9.0m EA402 extension cable form an exactly matched 10m tuned circuit; trimming the cable shifts the calibration frequency and ruins measurement linearity.
        How does the Vibro-Meter TQ402 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10 interface with a third-party PLC or DCS if a VM600 rack is not present?
        The Vibro-Meter TQ402 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10 outputs a raw high-frequency signal to the IQS900 conditioner. The IQS900 then converts this into a standard voltage output (e.g., -1V to -9V) or a 4–20 mA current loop proportional to vibration/gap, which connects directly to standard analog input cards on any Allen-Bradley, Siemens, or Honeywell DCS.
        What target material must be used to ensure the certified accuracy of the Vibro-Meter TQ402 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10?
        The Vibro-Meter TQ402 111-402-000-013 S3960 A1-B1-C042-D000-E010-F0-G000-H10 is factory-calibrated against standard VCL 140 steel (equivalent to European 42CrMo4). If your turbine shaft uses a significantly different alloy material, you must execute a manual target material re-calibration curve to adjust the signal conditioner's output scaling.
