| Wilcoxon Research adds a displacement sensor to its popular PC420 Series of 4-20 mA vibration sensors. The PC420D is the first IEPE displacement detector and 4-20 mA vibration industrial transmitter packaged as a single sensor. The PC420D sensor outputs a 4-20 mA signal based on the displacement level of the machine vibration. The 4-20 mA output is determined by first measuring the peak to peak vibration, then converting that level to a 4-20 mA signal. Because balance components tend to dominate the vibration spectrum when viewed in displacement units, the PC420D sensor is able to track the balance component of machines, one of the most sought after parameters. Integrating this signal into an existing PLC SUPPLIER, DCS or SCADA system simplifies real time health monitoring because vibration, formerly considered too complex, can now be trended in easily understood units of mils or millimeters of displacement. Measuring displacement can unmask hidden problems and provide data in easy to understand measurement units. Instead of converting to displacement after the measurement is taken, a common practice in diagnostic vibration monitoring systems which can introduce errors known as “ski slopes”, the PC420D sensor integrates at the measurement point for the cleanest vibration data. The PC420D is ideal for condition based monitoring and predictive maintenance of motors in the speed (frequency) range of 300 rpm to 60,000 rpm (5 Hz to 1,000 Hz). The PC420D can be widely used to monitor balance of plant industrial instrumentation such as pump motors, blowers, fan motors, compressor specification motors, and a wide variety of machine tool drive motors to significantly reduce failure rates in the field. |

With our new Laser-Distance Sensors DLS-B you measure absolute distances up to 500 meters. Thanks to state of the art laser technology the DLS-B device measures with a precision of 1.5 millimeters. It represents a cost efficient solution even at extreme environment temperatures as low as -40° C.
The DLS-B is an optical measuring device. You can measure, maintenance-free, distances on natural and reflective surfaces. You determine positions on objects difficult to access or with very high surface temperatures. Just as well you can measure distances in an aggressive environment in an easy and accurate way.
Serial, analog and digital interfaces are standard features for the complete DLS-B product line. This enables you to easily connect the DLS-B to a control system (SPS, IPC or PC)
The DLS-B device runs in a “Stand-alone-mode” and independently executes all programmed functions. Thanks to the flexible range of functions an external display can be connected directly to the DLS-B device via interface RS232 or RS422. Via a digital input, measurements can also be activated from an external button or switch.
For easy configuration of the DLS-B devices, the necessary software is at your disposal |

Magnetostriction - A Milestone in Measurement Technology
The heart of MTS sensors is the ferromagnetic measuring element, also known as the waveguide, and a movable position magnet that generates a
direct-axis magnetic field in the waveguide. When a current or interrogation pulse passes through the waveguide, a second magnetic field is created radially around the waveguide. The interaction between the magnetic field in the waveguide and the magnetic field produced by the position magnet generates a strain pulse which travels at a constant ultrasonic speed from its point of generation, the measurement point, to the end of the waveguide where it is transformed into an electric pulse in the sensor element. The resulting signal is processed by the specialized electronics of the Temposonics sensor. With our extensive know-how of ferromagnetic materials, magnetic effects and ultrasonic processes, MTS remains unrivalled in performance standards for non-contacting position measurement of the highest precision. |

The sensor outputs a signal proportional to the cable displacement through a hybrid potentiometer suppliers or an encoder fixed to the drum shaft.
The signal is then an analogue signal (voltage or current) or a pulse signal. |
