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.

Ultrasonic vehicle detection sensor for drive-thru lanes, gates, and parking garages. 5 m maximum range, 1 cm resolution, and ~250 ms between readings (~4 Hz), plus a preset 1.5 m proximity zone.

Near-field handling is built in: objects closer than 50 cm are reported as 50 cm for predictable behavior.

Interface is selected at purchase: Micro USB, TTL, or RS232. 

MB7900 Sensor to 4-20mA Signal Converter

The MB7900 is an optional add-on for most WR and TankSensor models, enabling seamless integration with systems that require a 4-20mA output. This converter provides a 4-20mA signal through an M12 (8-pin) connection, available in both male and female connector versions, or via flying leads.

With the MB7900, there’s no need for third-party adapters, daughter boards, or additional workarounds to achieve 4-20mA compatibility—everything is built into the solution.

Note: This is not a standalone product. It must be selected as a configurable option for compatible sensors. Selecting "4-20mA" under output will automatically add the MB7900 Sensor to 4-20mA Signal Converter to the sensor's build.

The MB7940 EZ Mounting Hardware Kit is for use with our EZ sensors without housing options. The included hardware gives customers easy access for through-hole mounting.

The kit consists of:

4qty M3 x 6 Screws
4qty M3 Nuts
2qty M3 x 6 + 6 Male/Female Standoffs
2qty M3 x 8 + 6 Male/Female Standoffs
2qty M3 x 10 + 6 Male/Female Standoffs
2qty M3 x 8 Male/Female Standoffs
2qty M3 x 10 Male/Female Standoffs
