  • Linear Amplifiers

    LA Series - Motion Control Systems, Inc.

    Motion Control Systems'' linear amplifiers are high performance servo controllers that produce very smooth sinusoidal motor currents using a linear amplifier output stage. In combination with a sinusoidally wound MCS brushless motor, the linear amplifier can achieve extremely precise rotational control with less than 1% torque ripple, no acoustic noise and almost undetectable levels of electromagnetic interference. Standard programmable features allow greater design flexibility, easy installation and start-up.

  • PD Monitoring Systems

    Power Diagnostix Systems GmbH

    The ICMmonitor is an instrument for continuous on-line monitoring of partial discharge activity in high voltage equipment. The instrument tracks changes in key discharge quantities for storage in trending diagrams and for triggering user-settable alarms. TCP/IP, Modem, fiber optic or direct serial links enable remote access and full remote control. The latest version of the ICMmonitor comes with spectrum analysis function (formerly know as SPECmonitor), acoustic signal detection, and a conventional partial discharge measurement circuit.

  • Decibel Meters

    PCE Instruments

    A decibel meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the device and acoustic measurement values are displayed. Here at PCE Instruments, we offer two types or classes assigned to decibel meters: type 1 / class 1 or type 2 / class 2. For assessing noise in basic industrial, commercial, educational, recreational or residential applications, a type 2 / class 2 decibel meter usually will suffice. For precision-grade assessments often made in a laboratory, a type 1 / class 1 sound level meter primarily is used.

  • Hydrophone

    TC4047 - Teledyne Marine RESON B.V.

    The TC4047 miniature hydrophone offers a useable frequency range from 1kHz to 170kHz. The hydrophone incorporates a high quality 20dB low-noise pre-amplifi er which provides optimal conditions for signal transmission. The high sensitivity provides excellent signal to noise ratio and immunity against induced cable noise. The hydrophone is omnidirectional up-to 100kHz and has uniform receiving characteristic from 1kHz to 100kHz. An insert calibration circuit enables remote testing of the hydrophone condition. The hydrophone comes with a SEACON connector. The sensor element is permanently encapsulated in Special formulated NBR to ensure long term reliability. The rubber has been specially compounded to ensure acoustic impedance close to that of water. The strainrelief and outer jacket of the cable is made of high density polyurethane. TC4047 can be used in sea or fresh water.
