Embodiments of a solenoid valve are provided. The solenoid valve includes a solenoid portion having a housing. The housing has a first bore and a second bore with the first bore adapted to receive a first end of an armature assembly and the first bore being surrounded by a magnetic coil. The solenoid valve also includes a valve body. The valve body is adapted to receive a second end of the armature assembly. The solenoid valve further includes a detection device located in the second bore and a detection plate interposed between the solenoid portion and the valve body. The detection device interacts with the detection plate to produce a signal indicating whether the solenoid portion is installed on the valve body.

In order to shift a rotation angle of a rotor to a region of a normal mode (for example, a region c) from a region of a heater cut mode (for example, a region e), the rotation angle needs to pass through a region where a flow rate of a refrigerant which is caused to flow through all branch channels becomes zero (a region d). When the refrigerant has a high temperature, there is a possibility of the refrigerant being not cooled, and boiling. Therefore, when a request to switch a normal mode and a heater cut mode is issued, permission/non-permission of switch of the mode is determined by comparison of a temperature of the refrigerant detected by the temperature sensor 26 and an upper limit temperature of the refrigerant.

A valve checker system includes a valve having a valve housing with an inlet side, an outlet side, and a valve element therebetween. The valve element is selectively and repeatably rotatable between a first closed position, wherein a seal is formed between the valve element and the valve housing, thereby substantially preventing fluid flow between the inlet and outlet sides, and an open position, wherein the seal is broken such that fluid flow is permissible between the inlet and outlet sides. The valve element is also selectively and repeatably rotatable within a discrete angle in a direction toward the open position, from the first closed position into a second closed position in which the seal is maintained between the valve element and the valve housing. A controller is operatively coupled to the valve element and configured to rotate the valve element between the first and second closed positions.

A housing of a solenoid valve unit for controlling a central clutch actuator of a utility vehicle is configured for installation in a transmission housing, preferably in a clutch case, and for accommodating at least one solenoid valve. The housing has an elongate housing shape that is curved along its longitudinal direction to enable installation in tight spaces.

Provided is a temperature sensor attachment structure capable of reliably fixing a temperature sensor and being retrofitted to a standard component. Provided is an attachment structure of a temperature sensor to be attached to flow path blocks or a fluid control device of a fluid control apparatus including the plurality of flow path blocks each of which includes a fluid flow path therein and on at least one surface of which has an opening portion of the fluid flow path, and the fluid control device placed on the flow path blocks. The attachment structure includes a rectangular temperature sensor attachment piece, and a pair of clamping pieces extending from opposite sides of the attachment piece facing each other.

In one embodiment, a multi-purpose sensor may couple to a machine operating in an industrial environment and include numerous sensors disposed within the multi-purpose sensor to acquire sets of data associated with the machine or an environment surrounding the machine. A first portion of the sets of data may include historical sensor measurements over time for each of the sensors, and a second portion of the sets of data may include sensor measurements subsequent to when the first portion is acquired for each of the sensors. A processor of the multi-purpose sensor may determine a baseline collective signature based on the first portion, determine a subsequent collective signature based on the second portion, determine whether the collective signatures vary, and generate signals when a variance exists. The signals may cause a computing device, a cloud-based computing system, and/or a control/monitoring device to perform various actions.

An electronic controller includes a housing. The housing has an opening configured such that a radio module is removably insertable into the housing, and a cover and plug are also insertable into the housing.

A system for delivering a fluid to a fluid consuming asset having a fluid tank is disclosed. An inlet of a manifold is fluidically coupled to a storage tank that contains the fluid to be delivered. A first distal end of a fluid transporting mechanism is fluidically coupled to an outlet of the manifold. A second distal end of the fluid transporting mechanism is fluidically coupled to the fluid tank. A primary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a first fluid level threshold. A secondary valve is fluidically coupled to the fluid transporting mechanism and restricts fluid flow to the fluid tank when fluid level in the fluid tank reaches a second fluid level threshold. The first fluid level threshold is lower than the second fluid level threshold.

A system for igniting a grill can include a solenoid valve, a flame rectification sensor, an igniter, and a control circuit connected to the solenoid valve and the flame rectification sensor. The solenoid valve controls flow of gas to the grill's burner and includes a switch that closes when a handle connected to the switch opens the solenoid valve. The control circuit sends current to the solenoid valve when the switch is closed to hold the solenoid valve open. After the switch closes, the igniter is ignited. After ignition, the control circuit monitors the presence of a flame with a flame rectification sensor. If no flame is detected after a certain amount of time, the control circuit stops sending current to the solenoid valve to close the solenoid valve.

Disclosed is a vacuum valve with a sensor arrangement having at least one inertial sensor, where the sensor arrangement is designed in such a way it detects a measuring signal with respect to an acceleration impacting on the valve.
