    • A service gauge for determining refrigerant pressure and the saturated vapor equivalent temperature, or other parameters, for a refrigerant in an HVAC system. In one embodiment, the service gauge employs a bourdon tube with at least one attached strain gauge to sense the refrigerant pressure and produce an electronic pressure signal. In another embodiment, a magnet and rotary position sensor produces an electronic signal proportional to the refrigerant pressure. The electronic pressure signal from the output of the strain gauge or the rotary position sensor is connected to a microprocessor, which calculates and displays the refrigerant pressure, the saturated vapor equivalent temperature for a variety of refrigerants, produces instantaneous and time lapsed representations of those parameters, and other parameters of the refrigerant.

    • A condensate pump for an HVAC system includes a reservoir for collecting condensate water, a pump motor connected to an impeller pump and a floatless pump control module. The floatless pump's microcontroller detects the water level in the reservoir and, based on the water level in the reservoir, controls the operation of the pump motor, and if necessary, sounds an alarm and shuts down the HVAC system. The floatless pump microcontroller may employ an ultrasonic transducer or capacitance sensors to detect the level of condensate water in the reservoir. The microcontroller implements a variable water lift feature. The microcontroller implements a self-cleaning feature to pump stagnant water out of the reservoir and to pulse water in the drain line and the agitation of the water in the reservoir and implements an anti-clog feature to clear a clogged drain line when an overflow condition is detected.

    • A multi-value capacitor with a safety disconnect mechanism has a capacitive element with six capacitive sections, a common wire, and six section wires enclosed in a cylindrical metal can with a metal lid that normally has a concave configuration. The wires are soldered to contacts extending through the concave metal lid. The safety disconnect mechanism includes an external insulator disk with terminals. The terminals in the insulator disk align with the contacts in the metal lid. The center common terminal of the insulator disk is fixedly riveted to the center common contact of the metal lid. Spring elements form the electrical connection between the section terminals of the insulator disk and the section contacts in the metal lid. If an overload condition occurs, pressure inside the sealed metal can causes the metal lid to spring from its concave configuration to a convex configuration, which causes the whole insulator disk to pop up and thereby simultaneously break the connection between all of the section contacts in the metal lid and the section terminals of the insulator disk.
    • 具有安全断开机构的多值电容器具有电容元件,其具有六个电容部分,公共电线,以及包围在通常具有凹形配置的金属盖的圆柱形金属罐中的六个部分电线。 电线焊接到延伸穿过凹金属盖的触点。 安全断开机构包括具有端子的外部绝缘体盘。 绝缘体盘中的端子与金属盖中的触点对准。 绝缘体盘的中心公共端子固定地铆接到金属盖的中心公共接触点上。 弹簧元件形成绝缘盘的部分端子和金属盖中的部分接触之间的电连接。 如果发生过载状况,密封金属内部的压力会导致金属盖从其凹形构造弹簧到凸出的构型,这导致整个绝缘体盘弹出,从而同时破坏了所有的截面接触件之间的连接 金属盖和绝缘子盘的端子。
