An attachment element for a static mixer and an attachment system with such an attachment element, the static mixer, and a pressure sensor. The attachment element has a flow channel with an inlet opening and an outlet opening arranged opposite the inlet opening in a longitudinal direction of the flow channel and designed as an injection nozzle. The attachment element is designed to be fastened at an inlet side having the inlet opening by a fastening unit of the attachment element on top of an injection tip of the static mixer. Furthermore, the attachment element has a receiving opening for the pressure sensor. The receiving opening extends from an exterior side of the attachment element to an opening in a subsection of a channel wall of the flow channel.

A manually-operated paint spray gun includes a body having a nozzle for atomizing paint to be sprayed and a handle forming a handgrip and provided with a connector for the inflow of compressed air to be supplied to the nozzle, wherein the handle of the gun has a compressed air regulator operatively associated to which is a pressure sensor at least part of which is arranged in a removable portion of the handle forming a substantial part of the dorsal area of the handgrip and is separated from the inflow connector.

A programmable networked variable atomizer (PNVA) assembly is provided. In one embodiment, the PNVA assembly includes an atomizing portion. The atomizing portion includes multiple miniature fluid control valves and an air assisted atomizing outlet. The PNVA assembly also includes a PNVA electronic module. The PNVA electronic module includes a microcontroller, at least one pulse width modulation driver, a wireless radio, a differential pressure sensor, and a laser targeting LED.

An error detection and flow rate monitoring system of a liquid fertilizer distribution system of an agricultural implement that can provide feedback to identify compromised flow states in the system and corresponding locations of potential blockage or component failure. The system may include pressure sensors that may be evaluated in pairs or otherwise analyzed comparatively to determine flow rate or other characteristics through nozzle assemblies. The pressure sensors may be mounted in the wet boom between the rows. A control system compares the pressure values before and after each row to determine the pressure drop across its nozzle assembly and may further use the pressure drop values to determine flow or application rates and corresponding errors in the pressure drop, flow rate, and application rate compared to their acceptable values and may provide feedback to identify a specific location(s) of potential blockage or flow-control component failure.

A system for indicating degraded operation of a robotic paint station is provided. The system includes a paint nozzle operable to spray paint upon a work piece, a paint supply tube system including a plurality of paint supply tubes operable to supply a flow of paint to the paint nozzle, a vacuum system connected to the paint supply tube system and operable to remove air pockets from the paint supply tube system, a pressure sensor connected to the vacuum system, and a computerized robot control module. The computerized robot control module is programmed to monitor data from the pressure sensor, compare the data to a threshold pressure value, and generate a maintenance warning indicating degraded vacuum system operation based upon the comparing.

A liquid spray boom for supporting a plurality of spray nozzle assemblies each having a compact design that enables transfer and storage of the spray boom with lesser tendency for damage. The spray nozzle assemblies each include a liquid inlet section and a pair of spray nozzle liquid supply and support legs extending from the liquid inlet section in forward transverse relation to the spray boom and at an acute angle to each other. A spray nozzle is removably mounted on each nozzle body liquid supply leg with a respective check valve disposed in rearward relation to the spray nozzle.
