Extensometer meets EN15000 and EN280 safety applications

The Model 182 extensometer is a specialty high-performance strain gauge-based force sensor from the VPG Transducers brand of Vishay Precision Group. It is designed for industrial, EN15000 and EN280 compliant off-highway vehicle and equipment safety applications.

The extensometer accurately measures deformation, or changes in the length of a solid structural body, with a 500μƐ full-scale sensing range and necessary redundancy for EN15000 and EN280 compliance in safety applications.

A robust design consists of a high-quality strain gauge sensing element, housed in a highly corrosion resistant coated alloy steel, with mounting via two bolt holes (M10 12.9 required).

Units are IP67 rated for dust and moisture protection, ensuring their continued reliability and repeatability in demanding environments.

Multiple output choices, including mV/V, 4-20 mA and 0-10V, are available as standard, along with alternate connection options.

For vehicle safety applications, customers can select from either a CAN Open or SAE J1939 protocol, with further choice of a DT or M12 connector.

Typical applications for the Model 182 include off-highway vehicle, telescopic handler and lifting machinery measurements.

The extensometer is especially well-suited for applications where safety and device stability are of critical importance for operator injury risk mitigation and prevention, including where stringent vehicle compliance with EN15000 and EN280 standards may be required.

It may be further specified for the accurate onboard vehicle machinery and chassis safety monitoring of construction equipment, scissor lifts, boom lifts, forklifts, and materials handling equipment.

Here, the extensometer effectively supports various lifting and loading scenarios, including overload measurements.
