Cheese Cheese making is essentially a dehydration process in which milk casein, fat and minerals are concentrated 6 to 12-fold, depending on the variety. The basic steps common to most varieties are acidification, coagulation, dehydration, and salting. Acid production is the major function of the starter bacteria.
A current transducer is a device that coverts alternating or direct electrical current signals into analog instrumentation signals so that they can be used and readily interpreted by certain industrial control systems.
What is a transducer and what are the differences between an active and passive transducer? Solution: A transducer is a device that converts input energy into output energy. Typically the output energy is differing in kind but related to the input. Active transducers generate electric current or voltage directly in response to environmental stimulation. Examples of active transducers are thermocouples and piezoelectric accelerometers. Thermocouples produce voltage difference on its terminals that is proportional to the temperature of the environment. Passive transducers produce a change in some passive electrical quantity, such as capacitance, resistance, or inductance, as a result of stimulation.
