Abstract: Circuitry including a resistance sensor is excited by an external power source. A reference voltage is established, the voltage developed across the sensor resistance is compared at an amplifier input with a reference voltage signal and the voltage across a feedback resistor, and the total current drawn through the circuitry adjusts as a function of the sensor resistance to give a balanced amplifier input. Total current may be made a linear function of sensor resistance or a non-linear function by proper selection of certain resistors.

Abstract: A differential pressure transducer of the capacitor type utilizing isolation diaphragms for sensing the differential pressure directly, and having a central chamber with a sensing diaphragm in the central chamber. The central chamber is filled with oil or a suitable liquid which transmits pressure from the isolation diaphragms to the sensing diaphragm. The sensing diaphragm forms a capacitor plate, and the walls of the chamber adjacent to the sensing diaphragm also form capacitor plates. The pressures are transmitted to the sensing diaphragm through the oil so that only differential pressure is sensed between the two isolation diaphragms. The sensing diaphragm and its chamber are made so that any excessive pressure causes the sensing diaphragm to bottom out against its mounting chamber surfaces. The unit is made extremely stable, by using a relatively massive metal housing with a glass center portion fused thereto, and depositing the metallic capacitor plate material right onto the glass surfaces which form the sensing chamber.

Abstract: A resistance temperature sensor adapted to be produced in a semiautomated manner and which is extremely rugged in construction. The basic lead and support element is made in long lengths and then trimmed to stock lengths and the resistance wire is then mounted and enclosed. The exact overall length of the resistance sensor can be altered to a particular customer''s requirements by trimming the lead and support assembly without substantially affecting the calibration of the resistance sensor. The sensor is constructed so that it is extremely rugged and insensitive to handling, and at the same time gives high accuracy.

Abstract: A pressure transmitter for sensing a pressure of a process fluid in an industrial process includes a pressure sensor body fluidically coupled to the process fluid configured to receive an applied pressure related to a pressure of the process fluid. The pressure sensor body has a high pressure region configured to deform in response to the applied pressure and a low pressure region configured to deform in response to the applied pressure. A high range resistor bridge circuit is mounted in the high pressure region having a powered node, a common node and an output node and has a resistance which changes in response to pressure applied to the high pressure region. A low range resistor bridge circuit is mounted in the low pressure region and has a powered node, a common node and an output node and having a resistance which changes in response to pressure applied to the low pressure region. A pressure output circuit couples to the output node of the high range resistor bridge and the output node of the low range resistor bridge and provides an output related to the applied pressure based upon a voltage difference between the output node of the high range resistor bridge and the output node of the low range resistor bridge.
