This pressure/depth sensor has built-in TE #39;s M10 size MS5837 series sensor. A protective cover is added to the fragile sensor membrane while ensuring fluid flow (complete drying is recommended once a day to prevent reading drift). Internal insulation design prevents galvanic corrosion. The sensor measures depths of 300 meters and is calibrated with a temperature sensor accurate to ±1°C. Model ELEC1-DS1-3026 offers the advantages of high chemical durability and metal shielding. - Protect cover for gel-filled sensor - Minimization of Electrochemical corrosion - Specification of package welding process - Locknut amp; scratch-proof flang
