MM Displacement Transducer

The MM displacement transducer uses strain gauge technology to provide a linearly proportional voltage output
in relation to movement. Its compact size and rugged construction make it ideal for a wide range of applications
such as geotechnical testing, R&D, aerospace, civil engineering, and automotive.

The strain gauge displacement transducer offers excellent accuracy — better than 0.1% on ranges of 0–25 mm
and 0.2% on the 0–50 mm and 0–100 mm versions — with infinite resolution and long-term stability.

The design incorporates a 4-arm active Wheatstone bridge with a nominal impedance of 350 Ω.
This design ensures excellent linearity, good temperature stability, and low current consumption,
making it ideal for battery-powered systems and equipment.

As a strain-gauge-based device, it is compatible with a wide range of standard analogue and digital instrumentation,
such as those used for load cells, pressure transducers, and torque sensors.

Operational Notes:

The outer case must not be distorted when clamping the sensor. A full-diameter clamp is advised.
The sensor is not recommended for use in hostile environments without additional protection.
Special tools are required to remove the plunger tip (anvil) to avoid damage to the spindle.
With the plunger tip (anvil) attached this forms a positive overload protection stop.
If the anvil is removed, the threaded end of the plunger must not be allowed to enter the case.
