HR8003 water level transmitter is one kind of pressure water level gauge which is used for measuring water level and temperature. With mixed signal processing technology it overcomes the shortage of the traditional analog circuit modules realizes F S digital linearity correction full temperature digital temperature compensation compensation data stored in nonvolatile memory multiple safety protection system to avoid the products cannot be used due to correction data lost; Circuit part with power and watchdog monitor which improve the reliability of the transmitter.
Rich product line it is widely used in water level and temperature measurement of industrial processesmining hydrology water conservancy geological exploration and other industries.
High quality and stability sensing elements
Anti-surge electromagnetic interference
Integral measurement of level and temperature
Reverse power protection over voltage protection
