Abstract: A two-wire field-mounted process device (16) with multiple isolated channels includes a channel that can be an input channel or an output channel. The given input or output channel can be coupled to multiple sensors or actuators (32, 34), respectively. The process device (16) is wholly powered by the two-wire process control loop (14). The process device (16) includes a controller (40) adapted to measure one or more characteristics of sensors (20, 22, 24, 26, 28, 30) coupled to an input channel (42, 44, 46) and to control actuators coupled to an output channel (48). The controller can be further adapted to execute a user generated control algorithm relating process input information with process output commands. The process device also includes a loop communicator (36) that is adapted to communicate over the two-wire loop.

Abstract: FLUID FLOW STREAM SENSOR HEATER An improved heater for use in a fluid flow stream sensor is disclosed. The sensor has an external surface disposed in the flow stream, a probe supporting a sensing means therein for sensing at least one desired parameter and a support coupled to the probe for positioning the probe as desired relative to the flow stream. The improved heater is connected to an external power supply . The improvement comprises a first heater disposed in the probe for heating the probe and a second heater constructed of a PTC (Positive Temperature Coefficient) material and disposed in the sensor in a thermally conductive relationship with the external surface thereof and electrically coupled to the power supply and to the first heater to provide heat to the sensor and to control heating of the first heater.

Abstract: A temperature transmitter (10) in a process control system includes a temperature sensor (16, 18) which senses temperature and provides a sensor output related to sensed temperature. An analog-to-digital converter (28) coupled to the sensor output provides a digitized output related to the sensor output. A microprocessor (22) receives the digitized output, compensates the digitized output and provides a temperature output. Comparison circuitry (12) compares the sensor output to a first threshold VREF1 and provides an inhibit signal to the microprocessor (22) if the sensor is outside of the first threshold VREF1.
