    Introduction 1. Introduction First of all we would like to thank you for trusting Kistler and using one of our sensors for your measurements. Please take the time to thoroughly read this instruction manual. It will help you with the installation, maintenance and use of this product.
  • Page 6: General Functional Description

    At the core of a piezoelectric pressure sensor there’s a synthetic crystal, with quartz being the most used materi- al by sensor manufacturers. Kistler additionally grows own high performance crystals called PiezoStar. Sensors based on PiezoStar crystals show several advantages over quartz based sensors as for example higher operat- ing temperatures, higher sensitivities, etc.

    However a special high impedance cable supplied by Kistler is es- sential to transport the incredibly small charges. Kistler offers dual-mode (PE and IEPE) multi-channel...
  • Page 8: Characteristics Of Pe Sensors And Measuring Chains

    The charge signal of the PE sensor needs to be transmitted through a special high insulation re- sistance cable that can be purchased at Kistler. The use of cheaper standard cables leads to drift and is therefore not recommended. Also, high impedance cables should be protected against humidity.
  • Page 9: Iepe Pressure Sensors

    IEPE sensors and decouples the subsequent voltage signal. So you just see the pressure signal. Kistler offers dual-mode (PE and IEPE) multi-channel charge amplifiers with integrated IEPE-Coupler and DAQ (digital and analog outputs) which can be connected di- rectly away to a PC through an Ethernet cable or through its analog outputs to an external DAQ system.
  • Page 10: Characteristics Of Iepe Sensors And Measuring Chains

    Piezoelectric Pressure Sensor Type 601C/603C 2.2.2 Characteristics of IEPE sensors and measuring chains  Only dynamic pressure measurements Whilst quasi-static measurements are possible with PE sensors, this is not the case for IEPE due to the fixed time constant in the built-in charge amp. Never- theless IEPE sensors are well suited to measure dy- namic pressures and pressure pulsations.
  • Page 11: Equipment

    The sensor version with short housing was primarily de- veloped for customers that want to replace their current Kistler PE pressure sensor (e.g. 601A, 6001, 6031, etc.) but still keep using the older accessories (e.g. connecting nipples, adapters).

    Five replaceable copper seals of Kistler Type 1131 are part of each sensor delivery. Replacement seals as well as nickel seals of Kistler type 1131A can be ordered sep- arately. It’s recommended to replace the sensor seal each time the sensor get demounted and mounted again.
  • Page 13: Adapter

    Adapters include one tube of lubrication grease Type 1063. It’s strongly recommended to apply a thin film of lubricating grease of Kistler Type 1063 to the external thread of the adapter before mounting. The lubrication prevents seizing of the threads and surfaces when de- mounting the adapter as well as sealing against high pressures.

    Nominally, the suggested passage diameter would be equal or greater than 20% of the passage length. For more information on this please contact Kistler. 60xC_002-741e-08.18 Page 13...
  • Page 16: Adapter Mounting

    Piezoelectric Pressure Sensor Type 601C/603C 4.1.3 Adapter mounting Fitting sensors into a mounting adapter greatly simplifies the installation process (when space and wall thickness are not a premium). Use of a mounting adapter will elimi- nate the need to provide a precise mounting configura- tion and allow the installer to provide only a threaded hole of the size and depth required for the adapter se- lected.
  • Page 17: Installation

    It’s strongly recommended to apply a thin film of lubricat- ing grease of Kistler Type 1063 to the external thread of the adapter before mounting. The lubrication prevents seizing of the threads and surfaces when demounting the adapter as well sealing against high pressures.

    Long time constant mode. Kistler pro- vides special insulation testers, such as Type 5493, to measure insulation resistance of high impedance cables.
  • Page 24 However never use air-blast to clean the connectors; it will unavoidably deposit a film of water vapour. Instead Kistler strongly recommends the use of cleaning spray Type 1003. Please contact your local sales centre should, after cleaning all connectors, drift or measure- ment of low insulation persist after cleaning all connect- ors.
  • Page 25: Calibration

    (sensor, cable, charge amplifier and data acquisition unit) should be considered. Re-calibration can be done in one of Kistler’s local tech offices or centres or by the customer itself if the appropri- ate calibration equipment has previously been bought.
