OptiMA Plug & Play System for 1-2 channel solutions

OptiMA – outstanding transmission distance up to 50 mm and protection class IP67

To simplify on-site measurement technology applications, MANNER Sensortelemetrie now also offers a module for automated adjustment of the rotor side and the stator side for all systems.

The inductively supplied measuring technology – sensor and measuring amplifier – are optimally matched to the stator system in several cycles. MANNER thus enables test engineers without extensive knowledge of sensor telemetry or training in this field to reliably and precisely record measurement signals on rotating shafts.

The new integrated automatic alignment enables optimum data and energy transfer between rotor and stator unit.

All inductive MANNER systems, including OptiMA, work without batteries or accumulators and are absolutely maintenance-free.

Annoying, heavy batteries with unbalance problems and their replacement are not necessary. This makes the rotor assembly a lightweight.

The OptiMA Kit at one glance

  • Sensor (DMS)
  • Sensor signal amplifier (in all common designs as well as a flexible substrate that can be wound around the shaft) with adjustment module
  • Rotor antenna kit (copper foil; ferrite; brass tape and cover tape)
  • Evaluation unit IP67
  • 1- and 2-channel operation (2 channel optional)

Application of an OptiMA Kit (rotor side)

Applied shaft with strain gauge sensor; 3c sensor signal amplifier and rotor loop

The system can be used directly and, if necessary, can be configured (sensor name; sample rate; information storage etc.) and calibrated (zero and gain settings) by the MANNER “RMC-Software”.

The adjustment module is miniaturized and therefore fits into all common MANNER amplifier housings. The module can be used individually or in conjunction with a Flex amplifier. In the latter case the adjustment module is directly integrated on the Flex sensor signal amplifier.

The module can be used both with our popular OptiMA sensor telemetry kit (evaluation unit with integrated receiving antenna and very long ranges (see Figure 1)) and with other antenna components such as the 8a Pick Up and the various evaluation units.

MANNER thus offers a plug & play system that can be configured in a consistent modular fashion.

The variants

OptiMArφ – on the shaft

Here the rotor antenna is laminated onto the shaft. The sensors are suitably placed and the measuring amplifier is applied to the shaft. You will receive all necessary components with the OptiMArφ Everything else is Plug&Play.

OptiMAxy – at the shaft end

For applications at the shaft end MANNER offers a rotor component which is screwed onto the shaft end. The sensors are placed and married to the rotor electronics. Everything else is Plug&Play.

Characteristic for all OptiMA systems is the large transmission and power supply distance of 50 mm between the rotating and the static component. This technology is purely inductive and therefore completely battery-free. As with all MANNER components, there are no signal drop-outs even in the event of strong electromagnetic interference. Thanks to the proven inductive transmission technology there are also no interference problems with radio frequencies. OptiMA is therefore the definition of robust sensor telemetry!

The system is ideal for, among other things:

  • wind power applications
  • propeller shafts on ships
  • Drive shafts in steelworks
  • for measurement technology for test benches
  • for diploma or student research projects in the field of mechanical engineering
