Accessories for MID 2014/32/EU Calibratable Length Measurement Systems tactile / non-contact

Sensor Cable

Shielded Cables

µSPEED-C10, C25, C50

Sensor cables for connecting the µSPEED sensors with the MID-COUNTER with lengths between 10 and 50 m (longer lengths on demand)

Display and Control Units

Serial Large Display

µSPEED-DIS

μSPEED-DIS is used to read μSPEED measurement values from a distance. The large display is equipped with 6 digits as standard, but can optionally be set up as 4 or 8-digit 7-segment display. Character height: 57 mm  

Label Printer

Printer for connecting to the MID-COUNTER

µSPEED-PRT

In some applications there is a need to provide the product measured in length directly with a label which contains the essential measurement data. This is done by the printer μSPEED-PRT.

Optical Adjustment Monitoring

Optical Adjustment Aid

µSPEED-OAJ-3-N

μSPEED-OAJ-3-N allows a fast and safe adjustment of μSPEED systems without the aid of meter sticks, spirit level or protractor. The adjustment aid OAJ3 is, among other things, for portable measurement applications, for measurements on rotating cylinders or in tight spaces and in applications with constantly varying material spacing.

Protection Casing

Casing for air cooling

µSPEED-HSEe

The casing μSPEED-HSEe made of stainless steel is used to protect the sensor head from contamination and from unsuitable ambient temperatures. The HSEe must be supplied with suitable purging air.
Casing for air cooling and water cooling

µSPEED-HSEw

The casing μSPEED-HSEw is used to protect the sensor head from contamination and from unsuitable ambient temperatures. The HSEw must be supplied with suitable purging air. It is designed for higher ambient temperatures due to the additional connection for water cooling. The HSEw contains two heat exchanger plates.
Heat Exchanger Plates

µSPEED-HE

Heat exchanger plates with 2 cooling water flange connections can be mounted on one or both sides of the sensor head. The water-rinsed heat exchanger plates allow the use of the sensor in a warm measuring environment.
Quick Cange Protective Glass

µSPEED-QCW

The μSPEED-QCW Quick Change Protective Glass is designed for use in harsh environments with heavily polluted ambient air. The QCW allows the replacement of the protective glass in seconds and allows the actual cleaning of the glass can be operated detached from the sensor.

Sensor Mounting Plate

Mounting Plate with Swivel/Slot Hole Element

µSPEED-MP

μSPEED-MP is set up via rotary element, which allows an angular adjustment of the sensor in the material movement direction by +/- 80 °. Slotted holes on the rotary element allow a distance adjustment of the sensor head.

Height Adjustment Unit

Adjustment unit for precise distance adjustment of the sensor head

µSPEED-HA

The height adjustment unit allows the sensor adjustment to be carried out with the diameter and thickness variations of the material being measured at the correct measurement distance.

Cable Guidance with Stand

Cable Guidance and Sensor Tripod with Laser Protection Casing

µSPEED-CGS

The cable guidance with tripod for the μSPEED sensor (μSPEED-CGS) always ensures the correct distance between the cable and the sensor as well as the correct routing of the cables. When the laser protection casing is opened, the laser switches off automatically.  

Laser Protection Equipment

Laser Protection Tube

µSPEED-TUBE

The sensor head TUBE for the μSPEED sensor reduces the risk of direct exposure of the laser beam. The TUBE can be combined with the laser shutter LSH.
Laser Shutter

µSPEED-LSH

The laser shutter μSPEED-LSH is used for the mechanical blocking of the laser beam. The shutter is manually activated by means of a sliding mechanism and is mounted on the front of the μSPEED system with four screws.
Optics

µSPEED-AO

The angle optics AO is used when the existing mounting space is very limited. The 90° angle optics makes it possible to manage with minimal space.
Laser Protection and Safety Monitoring

µSPEED-LSSC

The laser protection safety monitoring links various monitoring sensors to avoid any danger from the μSPEED laser. Laser class 1 may be achieved in conjunction with other protective measures.

Length Counter with Measuring Wheel Encoder and Parts Certificate acc. to MID 2014/32/EU

MID 2014/32/EU Tactile Calibratable Length Measurement

A measuring wheel runs along the medium to be measured. The measuring wheel is driven by the measurement object itself. The measuring wheel is mechanically connected to the machine and is held by a spring arm via the spring preload on the material to be measured. The encoder flanged to the measuring wheel sends a quadrature signal to the MID-COUNTER, which processes the signal and determines length values.

The basis for a good function and accuracy is a slip-free contact between the friction wheel and the measurement surface. Not all measurement surfaces are suitable for tactile measuring wheel scanning. In these cases, we recommend the use of non-contact laser encoders type μSPEED, which are also used in connection with the MID-COUNTER acc. European Measuring Instruments Directive MID 2014/32 / EU.
