Abstract: A mass flow meter is provided for measuring the mass flow rate of a material moving along a flow path. The mass flow meter generates a field of electromagnetic energy through which a material moving along the flow path passes. The mass flow meter includes a receiver that detects an amount of electromagnetic energy reflected from the material which is proportional to the concentration of material moving along the flow path. The amount of electromagnetic energy reflected and an assumed velocity are used to generate a response related to the mass flow rate of the material moving along the flow path.

Abstract: An apparatus and method are provided for calibrating a measuring transmitter which provides an output signal proportional to a parameter of interest measured by a sensor in the measuring transmitter without removing the measuring transmitter from its normal operating position. The apparatus includes a housing, a calibration sensor element located in the housing for sensing said parameter of interest, and a tube for coupling the housing to the measuring transmitter, thereby exposing the calibration sensor to the same parameter of interest as the measuring sensor in the measuring transmitter.

Abstract: An impact flowmeter includes a housing having an inlet end, an outlet end, and an interior region. The flowmeter also includes an inlet chute coupled to the inlet end of the housing. The inlet chute has an open end for discharging material into the interior region of the housing. The flowmeter further includes a load cell coupled to the housing for generating an output signal, and an impact plate coupled to the load cell. The impact plate is aligned with the inlet chute so that material entering the housing strikes the impact plate. The impact plate deflects the load cell in a measurement direction to change the output signal from the load cell based on the flow rate of material. The flowmeter still further includes a stop for biasing the load cell in the measurement direction to establish a preload condition on the load cell, thereby reducing the affect of vibration on the output signal from the load cell.

Abstract: A scale apparatus is provided for weighing material moving on a conveyor belt supported by an idler assembly. The apparatus includes a load cell support and a load cell having a base and a contact portion extending upwardly away from the base. The base of the load cell is configured to bend in response to a vertical force being applied to the contact portion to generate an output signal proportional to the force. The load cell is non-responsive to horizontal forces. The load cell is coupled to the load cell support, and the load cell support is coupled to a conveyor frame to suspend the load cell below the conveyor belt. The apparatus further includes an idler support for supporting the idler assembly. The idler support is coupled to the contact portion of the load cell.

Abstract: A scale apparatus is provided for weighing material moving in a downstream direction on a conveyor belt supported by a conveyor frame. The apparatus includes an upstream idler station, a downstream idler station, and a measuring idler station situated between the upstream idler station and the downstream idler station. The apparatus also includes a mechanism for measuring the weight of material moving on the conveyor belt. The measuring mechanism is coupled to the measuring idler station. The upstream idler station, the measuring idler station, and the downstream idler station are coupled together to form a scale unit. The scale unit is coupled to the conveyor frame so that the conveyor belt passes over the upstream idler station, the measuring idler station, and the downstream idler station.

Abstract: An enclosure for electrical components and the like is disclosed which protects the components in hazardous environments. The enclosure includes a unitary body having a generally cylindrical cavity and a closure securable to the body for closing the top of the cavity. A land within the cavity supports a first electrical component substantially normal to the axis of the cavity. Two pairs of longitudinal slots are provided for receiving second and third electrical components normal to the first component. A first internally and externally threaded outlet is situated at the bottom of the body substantially axially aligned with the cavity and second and third internally threaded outlets are located on opposite sides of the body generally above the land supporting the first component.

Abstract: A capacitive system for sensing the level of material includes a conductive member electrically connected to ground potential, a probe including a sensing element arranged to establish a capacitance between the sensing element and conductive member which is determined by the level of the material and a shielding element interposed between the conductive member and the sensing element to form an electrically neutral zone therebetween to thereby reduce the effect of a conductive buildup of the material on the probe on the capacitance between the conductive member and the sensing element, and a first circuit electrically connected to the sensing and shielding elements for applying generally the same electrical potential to both the sensing and shielding elements, the first circuit having an output which varies in response to a change in the capacitance between the conductive member and the sensing element.
