Ultrasonic snow depth sensor for weather stations and environmental monitoring. 5 m maximum range, 1 mm resolution, and internal temperature compensation.

Standard (~6 Hz Update Rate) or condensation self-cleaning (~0.5 Hz Update Rate) variants. RS232 or TTL serial plus analog voltage and pulse-width outputs. 

Near-field handling is built in: targets closer than 500 mm report as 500 mm for predictable readings.

MB7851 is a weather-resistant ultrasonic tank-level sensor with 1 mm resolution, 5 m max range, and ~2 Hz read rate. Output is selectable by wiring—RS232 or TTL serial, scaled analog voltage, or analog envelope; supply 3.0–5.5 VDC

Near-field handling is built in: targets closer than 50 mm are reported as 50 mm for predictable readings.

(Optional at purchase: 4–20 mA; requires 9–36 VDC and replaces standard outputs). 

MB7955 HR‑MaxTemp PCB and Heat Shrink

MB7956 MaxTemp cable sold per foot i.e. 1 ft = qty 1 (Purchased with the MB7955)

MB7957 HR-MaxTemp PCB, heat Shrink, and 3 feet of cable

MB7958 Assembled HR‑MaxTemp with 3 feet of cable

MB7959 Assembled HR‑MaxTemp with 6 feet of cable

MB7972 Assembled HR‑MaxTemp with 20 feet of cable

The HR-MaxTemp is designed to be used alongside the HR-MaxSonar sensors. The HR-MaxSonar sensor upon power-up will automatically detect an attached temperature sensor and begin to apply temperature compensation for the speed of sound changes to all range outputs.

The Flood Level Ultrasonic Sensor provides highly accurate non-contact measurement for flood detection and water level monitoring. With 1 mm resolution and models available in 5 m and 10 m max ranges, this sensor is designed for reliable operation in stormwater, municipal, and environmental monitoring applications.

Near-field handling is built in: targets closer than minimum range are reported as minimum range for predictable readings (300mm on 5m models and 500mm on 10m models.)

(Optional at purchase: 4–20 mA; requires 9–36 VDC and replaces standard outputs).
