A condition sensor for a fabric treating apparatus, such as a clothes dryer. A condition sensor is connected to a base wherein the condition sensor is operative to sense a condition such as moisture content for a multi-layered load placed within the dryer. The condition sensor comprises at least one support connected to the base wherein the at least one support has at least one extension attached thereto. A pair of capacitance sensors are attached to the at least one extension with the pair of capacitance sensors being arranged to build up charge through the condition sensor based on the moisture of the load content positioned in the dryer. A circuit is arranged to receive, read and generate signals in response to the charge of the capacitance sensors.

A dual-axes position sensor,having an outer housing,, an actuator,, a linear Hall effect sensor assembly,for detecting position changes along a first (y) axis, and a linear Hall effect sensor assembly,for detecting position changes along a second (x) axis is disclosed. The housing,is preferably made out of a non-magnetic material such as plastic. Actuator,is rod shaped and coupled to a movable device or shaft (not shown) that is to have its position sensed. The linear Hall effect sensor assembly,is unattachably positioned to set on lip,of the housing,, and includes a magnetically conducting pole piece,, a magnet assembly,comprising an upper magnet,and a lower magnet,that are separated by an air gap,. Magnet assembly,and pole piece,are positioned around a Hall sensor device support,in a&ldquo;U&rdquo; shaped configuration or form. Hall sensor device support,is fixedly attached to housing,via attachment area,. Linear Hall effect sensor assembly,also includes a positionally fixed Hall effect sensor element,attached to Hall sensor device support,on surface,. Linear Hall effect sensor assembly,is positioned approximately 90 degrees from and to linear Hall effect sensor assembly

A dual positional hall effect sensor 10 having an outer housing 12, an actuator 14, a linear movement sensor 20, and a rotational movement sensor device 22. The housing 12 includes a lower chamber 24 and an upper chamber 26, with a barrier wall 28 separating therebetween. The actuator 14 is made up of a coupling 32 for coupling to a movable device (not shown) that is to have its position sensed, a rod 34 that extends from the lower to the upper chamber, a collar 36 for retaining the actuator 14 within the lower chamber, and a key 38. The linear motion sensor 20 is unattachably positioned to set on collar 36, and includes a magnetically conducting pole piece 42 and a left and right magnets 44. The magnets 44 and pole piece 42 are positioned around the rod 34 in a 'U' shaped configuration. The lower chamber 24 also includes a positionally fixed hall effect sensor 46 and a spring 48 positioned between the barrier wall 28 and the collar 36. The rotational movement sensor 22, located in the upper chamber 26, includes a sensor housing structure 52 that has a groove or slide 54 for insertion and sliding of the key 38. The sensor 22 further includes a magnetically conducting pole piece 56 and a top and bottom magnet 58. A hall sensor 60 is positioned between the two parts of the magnet 58 and fixed in position relative to any rotational movement of the rotational sensor 22.

An instrument probe has two sensing elements; one is a self heated thermistor that serves as the air velocity sensor, and a second sensing element in the form of a chip thermistor, that are separately but simultaneously exposed, in the use of the instrument probe, to the air flow, with the self heated thermistor and the thermistor chip are incorporated in a self regulating bridge circuit, that, when the unit is powered, generates a non-linear signal that is applied to signal processing circuitry within the unit housing to adjust same for gain and off set with the resulting signal being applied to a linearizer circuit also within the unit housing wherein the signal is electronically processed to supply the unit output signal in the familiar 4-20 milliamp range. The transmitter device is arranged to be powered by either an alternating current or direct current supply that is in the range of about 22 volts to about 28 volts.
