Puristusmittarit

Puristusmittarit are instruments used to measure the pressure or compressive force exerted within a system, such as engines, hydraulic circuits, or structural components. The term is Finnish for “compression meters” or “compression gauges.” These devices convert a mechanical resistance into a readable quantity, often expressed in kilopascals (kPa) or bar. Typical puristusmittarit consist of a sensing element—such as a bourdon tube, diaphragm, or strain gauge—connected to a mechanical output or a digital display. Some models include integrated pressure sensors that output electrical signals for remote monitoring or data logging.

In automotive applications, puristusmittarit are most commonly employed to measure cylinder compression in internal combustion engines. The gauge is connected to a compression test head and a fitting on the engine’s cylinder head, allowing technicians to assess engine wear, valve integrity, and piston ring performance. In hydraulic and pneumatic systems, puristusmittarit monitor system pressure to ensure safe and efficient operation, supporting maintenance schedules and failure diagnosis.

Industrial puristusmittarit are available in a range of configurations, from simple analog gauges with dial indicators to advanced electronic meters with digital displays and communication interfaces (CAN, Modbus, Ethernet). The choice of meter depends on required accuracy, environmental conditions, and integration with control systems. Maintenance of puristusmittarit involves regular calibration, leak checking, and ensuring proper installation to avoid measurement errors.
