Pressure sensor for hydraulic pump application
2015-03-23

I have a pressure sensor as attached below which reads 5VDC and 9mA with and without pressure. The threaded male is 13.8mm diameter. This fits on a hydraulic pump Daikin, It has a number 07B17. The unit is Daikin ECH RICH EHU25 LO7 inverter controller motor pump, running oil at 45 bar for MIYANO cnc machine. The temperature is normal not more than 30 deg celcius
