Appl. No.:

29/151043

Inventors:

David Harris - Blaine MN
Bradley Slye - Plymouth MN

Assignee:

Electro-Sensors, Inc. - Minneapolis MN

International Classification:

0808

US Classification:

D 8349

US Patent:

6809531, Oct 26, 2004

Filed:

Feb 24, 2003

Appl. No.:

10/373424

Inventors:

Bradley D. Slye - Plymouth MN 55442
Daniel E. Bisila - Blaine MN 55434

International Classification:

G01R 2708

US Classification:

324714, 318663

Abstract:

A digital potentiometer device has a potentiometer, coupled to a reference voltage, that generates a voltage that can be varied. A programmable scaling function scales the reference voltage and the potentiometers wiper voltage depending on stored user variables. An analog-to-digital converter converts the scaled potentiometer voltage to a digital value readable by a controller circuit. The controller circuit controls the scaling function and display of the potentiometer position with the user variables.

Assignee:

Electro-Sensors, Inc. - Minnetonka MN

International Classification:

G01B 5/02
G01B 7/02
G01B 11/02

US Classification:

33 1PT, 33700

Abstract:

The linear distance measurement apparatus comprises a non-driven arm that is mounted such that an arc movement of the arm describes a linear distance. A rotary sensor mechanism is coupled to the non-driven arm. The sensor measures the arc movement of the arm and translates the arc movement to the linear distance.

Abstract:

The linear distance measurement apparatus comprises a non-driven, extendable/retractable arm mechanism that is mounted such that an arc movement of the arm describes a linear distance. A rotary sensor mechanism is coupled to the non-driven arm. The sensor measures the arc movement of the arm and translates the arc movement to the linear distance.

Appl. No.:

12/426380

Inventors:

Kris Paxton - Bloomington MN, US
Bradley D. Slye - Plymouth MN, US

Assignee:

Electro-Sensors, Inc. - Minneapolis MN

International Classification:

G01P 3/54

US Classification:

324173, 324166

Abstract:

A 2-wire, loop-powered shaft rotational speed sensor device that outputs a 4-20 mA current in response to the shaft rotational speed. The device is comprised of a sensor (e. g. , magnetic, optical) that senses an output from a sensor disk (e. g. , magnetic, optical) and outputs a series of voltage pulses whose frequency varies with the shaft rotational speed. A microcontroller measures this pulse frequency and generates a digital code representative of that frequency. A digital-to-analog converter generates an analog waveform in response to the digital code. A loop-powered, voltage-to-current circuit generates the output current in response to the analog waveform.

International Classification:

G01D 21/00

US Classification:

738665

Abstract:

A probe adaptor assembly includes a probe opening into which a probe can be inserted. The probe is held in place by a compression fitting such that the probe depth, with respect to a longitudinal axis of the assembly, can be adjusted prior to the compression fitting being tightened to secure the probe. A conduit adaptor port is provided. A lubrication fitting provides an opening for a lubricant to be injected into the assembly. The lubrication fitting is coupled to the probe opening so that the lubricant injected into the fitting can exit the probe opening in order to lubricate the system into which the probe is inserted. In one embodiment, the probe adaptor assembly is configured to replace a lubrication fitting for a bearing so that a temperature of the bearing can be monitored while also providing lubrication.

Inventors:

Bradley Slye - Plymouth MN, US

International Classification:

G11B 5/596

US Classification:

360078130

Abstract:

A sensor equipment guard is designed to fit over both the sensing mechanism and the sensor disk/switch while being coupled only to the sensing mechanism. The guard has a back section from which walls extend outward substantially perpendicular from the back and remains open behind the disk/switch. A connection mechanism couples the guard to the sensing mechanism. In one embodiment, the connection mechanism is integral to the guard.

International Classification:

B65G 21/20
E06B 7/00

US Classification:

1988361, 49 70

Abstract:

A sensor door with sliding rub block includes a pair of slots in the door through which mounting hardware is inserted to couple a rub block to the door. The slots enable the rub block to move relative to the door. A central slot between the pair of slots enables a sensor to be coupled to the rub block and move with the rub block.
