HPT612-W is full sealed submersible level sensor. It is made by building in high stable and reliable piezo-resistive silicon 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. HPT612-W level sensor has smart structure, high accuracy and good stability; it can be used for water or liquid measure and control of medicine, metallurgy, electricity, mine, city water supply and drainage and hydrology, etc. HPT612-W level transmitters is based on Zigbee wireless protocol and max transfer distance up to 400 meters, if add a wireless signal router, distance up to 800 meters. Characters: Accuracy: �±0.25%F.S. Wide working temperature scope Double supply by battery&DC power User-defined data transfer interval time With English level monitor PC software Highly-efficient lighting absorption and strong RFI & EMI resistance Remote signal transfer by Zigbee. 1.5 times range standard overload. 3 times range burst pressure CE approving Applications: well depth measurement and control water tank level measurement river level measurement and control wireless level monitor system Industrial course testing and control Building water supply systems Oil and Fuel Tank level measuring Automatic detection system Saving water to irrigate Liquid pressure and level measurement And so on
