Specifications for Pulse Radar Water Level Sensor

Non-contact radar water level sensors, with standard range up to ** 70 METERS (230 FEET) ** and accuracy of ± 3 milli-meters. Required data output is to be SDI-12 and RS-232 protocol utilizing a M12 pluggable connector, with power requirements of 10 to 16 volts (DC). Operation of unit is vital to be electromagnetic compatible (EN 61326, Class B) and is to propagate at a frequency around 26 GHz out of a 4-inch horn antenna. Environmental capacity for the sensor is to operate between -40 Celsius and +80 Celsius, with a NEMA 4X, aluminum coated IP65 housing. Each instrument must possess an internal LCD display for real-time readings, and must be visible with a windowed screw cap. The horn antenna is to be composed of 316L stainless steel, with an 8 degree beam angle for signal transmission. Maximum pulse energy is required at 1 milli-watt, average at 1 micro-watt.
