Time History Recording to Throughput Disc
For the most critical tests time history data can be recorded in parallel with vibration control with no reduction in control performance. The real-time throughput data capture function of the m+p VibControl system allows you to record all selected channels continuously in the time domain on the embedded data server (“throughput to disc”) irrespective of the channel count and the frequency range utilized. This means that you can always access all the original data for analysis purposes.

Measurement
Vibration Meter
The input signal of the Vibration meter software, which is the output signal of the accelerometer, i.e. the vibrational acceleration signal, is filtered by means of one of four possible digital band filters. Then, based on this signal, vibrational velocity and displacement signals are calculated by means of integrating filters. Thus, the software generates three signals which are transferred to the ZETLAB data server virtual channels created by the program and having the word “Acceleration”, “Speed” or “Displacement” in their names, respectively.Signals are averaged for a selected time interval (0.1 s, 1 s, or 10 s), after which the obtained values are displayed in the dialog box elements of the Vibration meter program. It is possible to display a root-mean-square (RMS), average amplitude or peak value.

Cryocoolers
DS Mini
The DS Mini cryocooler brings gas bearing technology to the mini-cryocooler market. The DS (Dual Split) features dual-opposed pressure wave generator pistons and a split cold head to reduce exported vibration and acoustic noise. The optional passive balancer will further reduce cold head vibration for sensitive applications. Both the cold head and wave generator can be mounted in any orientation. Using gas bearings in the pistons as well as the displacer, the DS maintains the core technologies of the well-established integral CryoTel MT, CT and GT cryocoolers. The DS Mini represents an advantage over flexure bearings due to its higher power density, while still offering a longer lifetime compared to rotary compressors and contact seals.

Electrostatic Capacitance-Type Gap Detectors
VE series
VE series are non-contact type of vibration/small displacement detector with high accuracy which can measure the distance between conductor such as metal and sensor’s surface in micron/submicron resolution. It demonstrates its best performance when used for the measurement and control of the axial and surface vibration of rotational shafts such as main shaft of turbines, electric motors, compressors, and of the thickness and width of moving objects. In addition to the measurement of the amount of displacement, a gap detector can also be used for a wide range of other measurement and control applications such as the measurement of the amount of slack or warping. The non-contact measurement process enables to apply no load to rotational or vibration body, and does not affect the material under measurement.

Distance Sensors - Functionality & How They Work
Distance sensors do not only measure the interval between the sensor and an object: A distance measurement sensor can determine fill levels, measure the dimensions of objects, check the positions of vehicles or objects and avoid collisions by detecting obstacles. In the industrial sector, more and more companies are using radar sensors for distance measurement. The reason: In comparison to an ultrasonic or laser distance sensor, radar sensors are able to measure reliably even in the presence of steam, smoke, dust, dirt, vibrations or extreme temperatures.

Loop-Powered Transmitters and Drivers
4-20mA
Loop-Powered Transmitters convert the output from proximity probes, seismic sensors, into a 4-20mA DC current, which is proportional to the input being measured. The transmitter converts the displacement or vibration signal to DC voltage and/or current for a DCS or PLC system. They control a 4-20mA current loop for a specified vibration range (ex. 0-5 mils peak-to-peak). The transmitters have a two-wire hook-up, powered solely by the loop current and have a power supply range of 15 to 36 volts.
