があった。In such a conventional measuring device, a calibration operation must be performed to convert the output of the load cell into a viscosity value, usually using a reference weight. As shown in a plan view in FIG.
A wire 15 is fastened to the support plate 10 in contact with the load cell 12 at a distance D from the rotation axis, and a reference weight is transferred to a weight receiver 17 via a pulley 14 rotatably engaged with the load cell fixing stand 13. Span calibration of viscosity measurement is performed by adding and subtracting by manual operation. Since this calibration work is performed manually, a shock or vibration is applied to the load cell 12 when adding or removing the reference weight, and the calibration work requires skill and is one of the error factors. A weight is used as a means for calibrating the anti-torque measurement span, and a 2 kg weight equivalent to 40 Mooney units (hereinafter, Mooney unit is represented by M) 2
The 100 M calibration is performed by manually adding and removing the weight and one 1 kg weight equivalent to 20 M to the weight receiver 17, or the 200 M calibration is performed using four 2 kg weights and two 1 kg weights. For this reason, when adding and removing a plurality of weights, there is a problem that a measurement error is caused by applying vibration or impact to the detection means 12 and the contact mechanism, and physical skill to be applied to a measurer at the time of calibration of the apparatus which requires skill in weight adding and removing operation. And there was a problem that psychological burden was large.
