Abstract
An electrical transducer connected to a computer-based system is temperature compensated by providing an assembly including the transducer, which assembly further includes a temperature transducer and a coding element providing a signal which is decoded by the computer to specify the zero shifts and sensitivity changes of the transducer at high and low temperature extremes.

A method of inputting to a microcomputer or the like input data which defines a value for each of a plurality of parameters so as to characterize an element, comprising the steps of:
- grouping the parameters such that there is provided a plurality of unique combinations each of which defines a combination of possible specific values for each of said parameters;
- assigning an electrical value corresponding to each of said unique combinations;
- providing for said element a voltage supply having an output coupled to said microcomputer;
- and
- adjusting said voltage supply so that the electrical value of said output equals the assigned electrical value corresponding to the combination of parameter values which characterizes said element.
In combination with an element which is characterized by a set of values for a plurality of defined parameters, an arrangement for providing a signature signal for said element to specify said set of values, said arrangement comprising:
- a voltage supply;
- and
- coding means coupled to said voltage supply for providing said signature signal, said signature signal having a value which directly corresponds to said set of values for said element.
A temperature compensated pressure transducer assembly adapted for connection to a computer-based system comprising:
- a pressure transducer;
- a temperature transducer;
- and
- means for providing a voltage having a coded value which can be decoded by the computer to characterize the zero shift of said pressure transducer at a first temperature and at a second temperature and the sensitivity change of said presure transducer at said first temperature and at said second temperature.
