Supply Oil Diesel Fuel Measuring Instrument, 4-20Ma RS485  Diesel Fuel Tank Level Sensor



Holykell Supply Oil Diesel Fuel Measuring Instrument,RS485 4-20Ma Diesel Fuel Tank Level Sensor .HPT604 made by building in high stable and reliable OEM piezo-resistive pressure sensor and high accurate circuit board into the stainless steel housing. Integrated construction and standard signal provide the user easy and convenient application in the local working place. The special cable connects with housing, can be immerged into the media for a long time.

For high temperature level application (up to 100 degree C), which is customized transmitters and manufacture with Germany sputtered film chips sensor, so the stability and quality very good.
