There are some pressure transmitters available but I think they are 4-20ma, 0-5volts or 0-10V. Can get 1-5v by placing a 250R resistor across the 4-20ma. There can be a loading issue with multiple devices. I don't how accurate they would be close to 0 Pa. Do a Google on pressure transducer, tons available. i.e. http://www.kamstrup-process.com/datashet/3601-1gb.pdf {slewrate} ----- Original Message ----- From: "Mauricio Jancic" To: Sent: Tuesday, November 12, 2002 3:31 PM Subject: [EE] 100Pa low cost presure sensor > Hi, anybody knows a suplier for a 0 to 100-200 Pa range presure sensor, with 0-20mA, 0-5V or anything like that as an output? -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
