Application in Automobile and Motorcycle industry
Measurement of piston behavior
Measure piston behavior(piston slap) by setting GAP-SENSOR in piston skirt and measuring a gap from a cylinder bore.
If provide fitting hole for setting the sensor, we offer setting the sensor. Setting thermocouple near the sensor is useful for measuring temperature and correcting temperature drift.(We offer set temperature drift)
Measurement of a gap from connecting rod bearing
Measure a trajectory of the center of an axis by setting a sensor in bearing of connecting rod and measuring a gap from crank pin.
Consult with us to select size of the sensor by depending on the connecting rod. In case choosing PU-03A type and the size of a fitting hole is φ6, measuring range is 0 ~500μm.
Measurement of a gap from crankshaft ②
Measure behavior of crank journal by setting a thin sensor in the main bearing of the crank journal.
As a fitting hole depends on size of a main bearing, consult with us.
Measurement of valve lift ①
Measure valve lift without processing valve, so weight of the valve does not change.
However, firing operation can not be conducted because of setting sensor inside combustion chamber.
Measurement of valve lift ③
Measure several valve lift at the same time by setting sensors in several valve guide.
A small sensor can measure it by performing taper machining in a part of valve system when firing.
Displacement measurement of a gasket
Measure gaps or displacement between a gasket and cylinder head or cylinder block by setting a thin sensor in a cylinder gasket.
Consult with us to select size of the sensors depending on thickness of gasket.
*Thickness of gasket needs more than 1.2mm.
Measurement of wheel balance
Measure balance of wheel by setting sensor near targeted wheel.
Consult with us to select size of the sensor according to measuring points.
Vibration measurement of a pulley and belt
Measure vibration of a pulley and belt by setting a sensor near the pulley and belt of automatic CVT type.
Consult with us to select a sensor according to vibration amount.
Displacement measurement of a piston ring
Measure behavior of piston ring(up and down motion) by setting a sensor in piston land(piston ring side).
Consult with us to select size of the sensor according to size of the piston.
Gap measurement of a crank shaft①
Measure behavior of a crank journal by setting sensor in the main bearing of the crank journal.
Consult with us as a fitting hole is different according to the size of the crank journal.
Rotation measurement of a turbine and compressor
Measure rotation speed by setting a sensor against blades of turbine or compressor.
Moreover, the sensor can measure shaft vibration by setting it against the shaft.
We select a sensor according to a gap and size of a turbine. Consult with us as we have countermeasure products for operating temperature and frequency characteristics that is over the specification.
Measurement of valve lift ②
Measure several valve lift at the same time by setting sensor inside combustion chamber.
A target pin needs to be set on a target in this measurement method, but it allows a small sensor to measure long stroke that conventional sensors cannot measure.
Moreover, the sensors can be used even in oil.
Runout measurement of a brake disk rotor
Measure runout of rotation by setting a sensor against surface of the brake disk.
Consult with us as we have countermeasure products for higher operating temperature than the specification.
Measuring example by using a slip ring
Measure behavior(up and down motion) of a piston ring by setting a sensor in piston land(ring side).
Generally, extracting an output by using slip ring cause a noise problem, but this type resolve the noise problem.
