Abstract: A unit which combines a remotely programmable controller with an integral temperature and level sensor for controlling the temperature and level of a given liquid. The device comprises one temperature sensor, to measure a liquid's temperature and to provide an electrical output; one level sensor, to measure a liquid's level and provide an electrical output; a programmable scaling and control module, for receiving the electrical outputs of the temperature sensor and level sensor as input signals, for scaling the temperature signal as a function of temperature and a scale-selection input, and for implementing a control logic to process the sensor signals into two respective control signals; two electronic switching devices, to electrically interface one of the two control signals to an external heater or cooling unit and the other one of the two control signals to an auxiliary device, such as a pump or alarm.

Abstract: A remotely programmable integrated sensor transmitter device for measuring and reporting a physical quantity of a given medium comprises a sensor for measuring a physical quantity of a medium and providing an electrical output as a function of the property measured, a scaler module for receiving the electrical output and for producing a scaled analog signal as a function of the physical quantity and a scale selection input, and a data interface for receiving programming data from an external computer and for providing the scale selection output to the scaler module.
