Enclosures
exchanger and air-conditioner equations include the exposed surface area of the cabinet -- enclosure bottoms and sides resting against walls and floors are ignored. Intended use is important because some industries such as petroleum and food processing enforce rules. Enclosures | Machine Design. Skip

GapmanGen3 Electronic Gap Measurement System for Aircraft Applications
to an earth grounded or conductive target, the. sensor measures a capacitance proportional to the air gap. When the signal is. input to a specialized signal conditioner amplifier, the output range can be. linearly ratioed between 0 10.000 VDC. This resulting output has a ratio of. one part in ten

Use of Non-contact Thin Gap Sensors in Controlling Coater Gap Uniformity
positioned parallel to an earth grounded or conductive target, the sensor/ guard combination measures a capacitance proportional to the air gap. When the signal is input to a specialized signal conditioner amplifier, the output can be linearly spread between 0 – 10.000 Vdc as related to a gap
