The TDM2500 is a very high quality, highly accurate 4-20mA output transducer, 0-2500 PSI, (2 FT)(2 wire) cable, and has a 10-30 VDC input voltage. The transducer pressure cavity is machined from a solid piece of 17-4PH stainless steel. The standard version has a 1/4NPT pipe thread allowing a leak-proof all metal sealed system. (Possible future availability oa 1/8 NPT.) There are no O-rings, welds or organics exposed to the pressure media. The durability is excellent. Derived from aerospace applications... this OEM commercial and industrial grade transducer made specifically for ADI is a superior choice for the electro-hydraulic retractable gear systems in todays high performance homebuilts. HY-TDM2500 specifications: 10-30 VDC input voltage... 4-20mA output current.. 0-2500 PSI range... 17-4PH stainless steel construction.... <1% accuracy, (when combining linearity,hysteresis, and repeatability) burst rating: 5X (12,500 PSI)
