A switch will always have somedeadband, which is the difference between the two operating points (opening and closing points). Deadband is required, because if a switch would open and close at the same point, it could start oscillating when the pressure is on that limit. Also, it could con...

The specific pressure level at which the snap-action switch activates, either opening or closing the circuit in response to the pressure change. Actuation Value/Deadband The difference between the actuation point and the re-actuation point in a pressure-actuated switch, defining the range between s...
(4) does not provide this information. The fitting therefore matches the expected mechanosensitive switch function, because it shows that the N1/N2 equilibrium is exactly poised in the middle, and is therefore in exactly the right place to be affected by external factors such as binding partners...
These can be used to switch an electric signal when a preset pressure is reached. They can be used to detect an overpressure situation, such as regulator failure, or they can detect an underpressure condition, such as a gas cylinder being depleted of contents. Many switches are very similar...
I followed cslynch's advice and changed the nib and sure enough, photoshop recognized the pen pressure (without even closing and re-opening PS). It's worth noting that I didn't actually change the nib. I simply opened the pen, pulled out the nib,...

This type of pressure detector is suitable for opening, closing, and switching the circuit when the actual pressure value changes to the adjusted switching point (rated value). The switch point can be adjusted on the dial for convenience a...
At present, testing of the switches requires removal of a cover plate so that an ohmmeter can be connected across the switch terminals to sense whether or not the switch is opening and closing properly. Also, the fitting for the air line leading to the switch must be disconnected and ...
The present invention relates to pneumatic valves and more particularly to intermittent opening and closing of pneumatic valves for operating wells in the oil and gas industry using a pressure switch. BACKGROUND Oil field pumpers (“Pumper”) are individuals that operate and maintain oil and gas pr...
