Submersible Level Transmitter Series BQA200
BQA200 submersible level transmitter is made by building in high stable and reliable piezo-restive 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 immersed into the media for a long time. It has compact size, light weight 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.

--Signal wire can use the double strand. We recommend the shielded wire in the situation with serious electromagnetic interference and please properly connect the wire to the ground. Don’t put the signal cables into a metal tube with other power cables or put them in the same slot, and decorate the wire far away from strong electric facilities.
--Signal lines can be floating or grounding at any point in the signal circuit, the transmitter housings can also be earthed or grounded.
--As the transmitter's ground through capacitive coupling, when checking insulation resistance, above 100V magnetometer can't be used, when checking circuit please under its max voltage,45V.
