MSI-F Series Linear Position Sensor with Analog Output

Flexible, high-accuracy absolute non-contact magnetostrictive position sensor for stroke lengths from 900 up to 20 000 mm.

Position measurement is performed using ring-type position magnets moving along the waveguide without mechanical contact, ensuring wear-free operation and long service life.

The sensor flange is made of high-grade stainless steel, providing excellent durability and suitability for harsh industrial environments.

The MSI-F supports sensor lengths of up to 20 meters. Thanks to the flexible waveguide design, the sensor can be supplied in compact packaging (900 × 900 × 100 mm), allowing safe transportation regardless of the measuring length.

Mounting recommendations

Flexible Waveguide
A sensor with a flexible waveguide is used in vertically installed hydraulic cylinders, as well as in applications that require non-standard measurements, both in terms of length and motion. The Teflon coating of the waveguide allows the sensor to be used in harsh environments with high levels of contamination.

Position measurements are performed using ring-shaped magnets that move along the sensing rod without physical contact. The sensor with a flexible waveguide can be mounted either inside the hydraulic cylinder or on the equipment using special clamping brackets.

INSTALLATION WITHOUT AUXILIARY TUBE

The minimum bend radius is 250 mm. Exceeding this limit may cause irreversible damage to the sensor waveguide due to stretching and deformation.

INSTALLATION WITH AUXILIARY TUBE

The sensor flange accommodates the installation of an auxiliary tube with the following dimensions:

- Outer Ø 10 mm, inner Ø 8 mm, maximum length 8 meters

- Outer Ø 12.7 mm, inner Ø 8.5 mm, maximum length 20 meters

The auxiliary tube must be made of non-magnetic material. For horizontal installation, clamping brackets must be installed every 500 mm.

For ordering the auxiliary tube:

Ø 10 mm: order code 100HFXXXXX, where XXXXX = stroke length in mm + 150 mm

Ø 12.7 mm: order code 127HFXXXXX, where XXXXX = stroke length in mm + 230 mm

Example:

For a sensor with a 900 mm stroke length, order code: 100HF01050

For a sensor with an 8500 mm stroke length, order code: 127HF08730

Interface

The analog sensor connects directly to the control system or indicator. The integrated microelectronics provide normalized output signals proportional to the position.

VOLTAGE OUTPUT:

CURRENT OUTPUT:

Multi-position measurement

A sensor with an analog interface can process the signal from two position magnets located on the same waveguide. To obtain position information for each magnet, two conditions must be met:

  • Measurements must be taken with a spacing of at least 76 mm
  • The sensor configuration (specified at the time of order) must support multi-position measurement

OPERATING MODES

Application options

• Single-position sensor (standard) for position or velocity measurement.

• Dual-position sensor for simultaneous measurement of two positions.

Connection example

CONNECTION DIAGRAM FOR DEVICE WITH PASSIVE SENSING CHANNEL

Setting

The main difference between an analog signal and a digital signal is that the analog signal has a reference point. When replacing a failed sensor, equipment recalibration is required in most cases. This can be performed in two ways:

  • If the customer’s machine includes a calibration function, new end positions are assigned in the control system after sensor replacement by moving the mechanism manually.

  • Alternatively, using the MSI-253 124 handheld programmer, new end position values can be programmed directly into the sensor. The procedure is similar to the first method; however, in this case the values are stored in the sensor rather than in the customer’s control system.

MSI-253 124 HANDHELD PROGRAMMER

Description:

Handheld programmer for analog sensors of the following series:

MSI-H,

MSI-P,

MSI-D,

MSI-F.

Functions:

Programming of the measuring range, output signal inversion.
