3. CIMS MK IV: FUNCTION, CHARACTERISTICS AND SCOPE OF DELIVERY
3.1. FUNCTION
The Cylinder Integrated Measuring System (CIMS) is an integrated displacement measuring
system for use on hydraulic cylinders with an Enduroq 2000 series piston rod coating or the
previous CEC coatings. Grooves underneath the piston rod coating cause a variation in the
magnetic field from the permanent magnet inside the CIMS. The CIMS Hall-effect sensor elements
measure the magnetic field and its variations. Their signals are fed into a micro controller which
calculates the position inside the groove and generates the incremental RS422 output signal. The
sensor and electronics are protected by a robust stainless steel housing, which can be installed
into the head of the cylinder.
Although CIMS Mk IV has a completely new housing, sensor and electronics, which provide
several new features compared to the previous CIMS Mk II / III, it is mechanically and electrically
compatible with CIMS Mk II / III, except for the standard connector that changed from a 6-pin
connector to a 9-pin connector.
3.2. CHARACTERISTICS
CIMS Mk IV features:
High accuracy combined with unlimited stroke lengths.
Sensor integrated in sealing flange, out of the pressure zone of the cylinder.
Easy installation or replacement possible without infringement of the hydraulic integrity of
the cylinder.
Very robust stainless steel housing, protecting the electronics from almost any
environment.
Waterproof, IP68 up to 10bar (depending on output connection type).
Upon request available for potentially explosive atmospheres, ATEX zone 1 certified.
Reliable redundancy possible with multiple CIMS sensors per cylinder.
Contactless operation, no contact between sensor and cylinder rod, no slide pad.
No (manual) calibration necessary, CIMS Mk IV will automatically compensate for mounting
tolerances, magnetic disturbances and temperature effects.
Diagnostic output, gives the possibility to (continuously) retrieve information about sensor
status, sensor identification, current position (since last power on), error codes, etc..
