More Info About pin on disc tribometer actually pin on disc tribometer which allows the friction coefficients of different lubricants to be accurately assessed and compared. Users in the field of automotive engine oils are not necessarily interested only in the lifetime of a particular lubricant but also in a quantitative method of determining the service frictional properties. This means that a service temperature of 100-140°C must be maintained during the test and that a load arm capable of compensating for thermal drift must be used in order to reduce discrepancies in the frictional signal. The standard pin-on-disk Tribometer uses a simple load arm with a tangential force sensor mounted close to the contact point so as to reduce errors due to arm compliance. However, for elevated temperature use, a different configuration is needed to avoid local heating and dilation within the sensor. For this reason a load arm from a CSM High Temperature Tribometer was adapted and fitted to a standard Tribometer. This arm uses two LVDT (Linear Voltage Differential Transformer) sensors which measure the tangential force independently after which an average value is computed and plotted as either a straight or an integrated signal. The sample is clamped in an oil bath (see Fig. 1) and an external heating element is located around the sample so as to give homogeneous heating. A thermocouple is placed in the bath in order to accurately monitor the sample temperature. A separate regulator controls both heater and thermocouple. The oil bath shown below can be supplied on request together with the necessary fixture for securely clamping the sample. refered by http://www.csm-instrumentsModified-Pin-on-Disc-Tribometer-for-controlled-lubricant-studies
