Abstract: A vibrating fork liquid level switch includes a vibrating fork assembly arranged to vibrate at a first frequency when in contact with a process fluid and at a second frequency when in contact with air. A drive circuit connected to the vibrating fork assembly is configured to drive the vibrating fork assembly into oscillation. Sense circuitry senses an oscillation frequency of the vibrating fork assembly. Output circuitry provides a first output when the sensed oscillation is at the first frequency and a second output when the sensed oscillation is at the second frequency. Control circuitry controls power applied to the vibrating fork assembly by the drive circuit between a first and a second power level. Verification circuitry verifies the oscillation frequency of the vibrating fork assembly when power applied to the vibrating fork assembly by the drive circuitry is changed.

Abstract: A process fluid temperature calculation system includes a first temperature sensor disposed to measure an external temperature of a process fluid conduit. The process fluid temperature calculation system has a stem portion having a known thermal impedance. A second temperature sensor is spaced from the first temperature sensor by the stem portion. Measurement circuitry is coupled to the first and second temperature sensors. A microprocessor is coupled to the measurement circuitry to receive temperature information from the measurement circuitry and to provide an estimate of temperature of process fluid within the process fluid conduit using a heat flux calculation.

Abstract: A heat flux temperature sensor probe includes a first mineral-insulated cable portion and a second mineral-insulated cable portion. The first mineral-insulated cable portion has a first metallic sheath, a first plurality of thermocouple conductors extending therein, and an inorganic insulative material insulating the first plurality of thermocouple conductors from one another and from the first metallic sheath. The second mineral-insulated cable portion has a second metallic sheath, a second plurality of thermocouple conductors extending therein, and an inorganic insulative material insulating the second plurality of thermocouple conductors from one another and from the second metallic sheath. A first thermocouple is formed between at least one of the first plurality of thermocouple conductors and one of the second plurality of thermocouple conductors proximate a first end of the second mineral-insulated cable portion. A second thermocouple is formed between at least two of the second plurality of thermocouple conductors proximate a second end of the second mineral-insulated cable. A sheath is operably couped to and connects the first and second mineral insulated cable portions, a portion of an interior of the sheath is filled with a non-conductive material.
