Calibration bath with stir motor closed-loop control and stirring viscosity detection and adjustment
A calibration device includes a tank, a propeller disposed within the tank, a motor coupled to the propeller, a processor coupled to the motor, and a memory. The memory stores instructions that, when executed by the processor, cause the motor to rotate at a specified speed based on input an indication of an actual speed of the motor. The memory may store instructions that cause the device to dynamically change the speed of the motor based on the viscosity of a fluid in the tank, which changes as the temperature of the fluid changes. In addition, the memory may store instructions that cause the device to determine whether the fluid in the tank is deteriorated, and to provide an operator alert in response to determining that the fluid is deteriorated.
