Inquiry (采购产品): Looking for info/quote on pressure switch... Need info/quote on adjustable-actuation point pressure switch(es), capable of good repeatability. Switch must be adjustable to within the following parameters: air pressure generated in a vertical tube (top end sealed) from water ranging from 1"min to 24"max above open bottom of tube (i.e. pressure = displacement of tube + air). Switch must also have a Deadband of approximately 0.25". Switches are for aquarium water level/property control for system in development stage.... So far, pressure switches have been too costly and/or unreliable... Essentially, I am looking for a pressure switch to be used in the role of air column pressure switch(sensor). Initial quantities would unfortunately be limited, but there is a great need for a reliable, cost-effective system such as the one I am working on. I am looking for a single supplier whose price is reasonable... Can you help? **** Hidden Message ***** Paul Littizzio 81 Glenwood Rd Rutland, MA 01543 USA Company: Aqua-Tarium Title: owner/operator Phone: (508) 886-2440 E-mail: plittizzio@charter.net **** Hidden Message ***** plittizzio@charter.net
